A Chapter of HFR’s Buyer’s Guide to High-End Audio
CH Precision occupies a specific position in the high-end audio landscape. Since its founding in 2009, the Swiss company has been an independent, engineer-led manufacturer of reference-tier electronics that share a distinctive design philosophy: modular card-cage architecture, adjustable global-versus-local feedback ratios, fully discrete signal paths, and a commitment to keeping products in service through multi-generational upgrade paths. Products CH introduced in its early years remain in the current lineup today as evolved versions, and the same modular slots that an early-2010s owner could specify are still available to a 2026 owner considering the same product.
The founder and CEO, Florian Cossy, is an EPF Lausanne–trained electronic engineer who spent four years at Goldmund, working his way up to amplifier designer. His co-founder, Thierry Heeb, was a digital and software specialist who designed the digital filtering technology that appears in every current CH digital product. The two left Goldmund to found the OEM company Anagram Technologies, and in 2009, with the encouragement of a group of distributors, they founded CH Precision. Thierry Heeb passed away on July 22, 2024; Florian Cossy continues to lead the company’s engineering team, which has grown to twenty employees including six engineers.
For a buyer approaching CH Precision for the first time, three things are worth knowing up front. First, CH is a genuine reference-tier brand — the current lineup spans from the I1 integrated amplifier up to complete 10 Series systems that can exceed $250,000. Second, the modularity and upgrade philosophy is central to what CH is — buying a CH means buying into a platform that evolves rather than an object that depreciates. Third, CH Precision has remained fully independent under founding ownership since 2009, with no corporate transitions or acquisitions to date — a rare position among high-end brands in 2026.

The CH Precision story begins not in 2009 but roughly two decades earlier, in the Swiss high-end audio scene of the 1990s. Florian Cossy graduated from EPF Lausanne and was hired by Goldmund upon graduation, spending four years there working his way up to amplifier designer. Goldmund’s original design philosophy had been established by engineers contracted from a company called Swiss Physics — an emphasis on wide bandwidth and high slew rates that shaped Goldmund’s amplifier voicing.
Cossy was, by his own account, content to follow Goldmund’s blueprint for a time, but he had ideas for changes he believed would produce greater stability and more consistent performance. When Goldmund’s leadership was unwilling to pursue those changes, Cossy began looking for other options. In parallel, Cossy’s longtime friend Thierry Heeb was encountering his own frustrations in Goldmund’s digital division. The two left to found the OEM company Anagram Technologies in the early 2000s, focused on digital audio — specifically DAC and signal-processing modules that other manufacturers could license and integrate into their own products. The two also founded a company called Orpheus during this period, before going on to start CH Precision together.
In 2009, with the encouragement of a group of distributors, Cossy and Heeb founded CH Precision — the name drawn from their initials, and, coincidentally, matching the ISO country code for Switzerland (Confoederatio Helvetica). The first CH Precision product, the D1 CD/SACD transport, landed in 2010. It was joined over the following years by the C1 D/A controller, the L1 dual-mono line-stage preamplifier, the P1 phono stage, the A1 stereo power amplifier, the M1 monoblock power amplifier, and the I1 integrated amplifier. Each product was engineered with modular card-cage architecture from the outset — an unusual design commitment for a small independent that meant significantly higher engineering overhead in exchange for products that could evolve over their service life.
The A1 was extensively redesigned to become the A1.5, and the M1 was upgraded to become the M1.1. The D1 became the D1.5; the C1 became the C1.2. All are still on CH Precision’s current order books. The A1 is the only original product no longer in production — an unusually strong long-term commitment for a small Swiss high-end company. Over more than fifteen years of continuous production, CH’s approach has established a distinctive market position: buyers commit to a platform, not a moment-in-time product.
CH later announced the 10 Series — a reference tier positioned above the 1 Series, using the same modular architecture but with reworked PCB layouts, elevated component selection, and dual-chassis topology where the power supply is housed in a separate enclosure. The L10 line-stage preamplifier and M10 monoblock power amplifier were the first 10 Series products to ship. The C10 D/A processor followed, receiving Stereophile review coverage from Jim Austin. The P10 phono preamplifier was announced at Munich High End 2025 and is now in production.
CH Precision has also expanded through a related-brand acquisition: the company now owns Wattson Audio, a smaller Swiss streaming brand whose Madison streamer uses variants of Heeb’s spline-filter technology. Kevin Wolff, CH Precision’s Director of Global Sales, also handles US distribution for Wattson.
CH Precision remains independently owned. Florian Cossy continues as CEO, and the company’s engineering team — now twenty employees, including six engineers — carries forward the design philosophy Cossy and Heeb established together. Thierry Heeb, who specialized in digital filtering and processing, passed away on July 22, 2024. The Préverenges facility west of Lausanne remains the manufacturing home. No corporate transitions, no external investment, no acquisitions of CH itself. The company that shipped its first product in 2010 is structurally the same independent company shipping the 10 Series in 2026.
CH Precision offers two product families: the 1 Series classic components and the 10 Series reference tier. Both share the same modular card-cage architecture and adjustable-feedback philosophy; the 10 Series adds dual-chassis topology with dedicated power supplies, reworked PCB layouts, and elevated component selection. All products are manufactured in Préverenges, Switzerland, with chassis boards built by a third-party Swiss manufacturer and final assembly, tuning, and testing at CH’s own facility.
The 10 Series represents CH Precision’s cost-no-object statement, built on the same modular platform as the 1 Series but with every assumption reconsidered from first principles. Each 10 Series component uses dual-chassis topology — the main electronics in one enclosure, the dedicated power supply in a separate enclosure, connected by an umbilical — to maximize isolation and preserve signal integrity.
The L10 is the 10 Series line-stage preamplifier. The two-box version is priced at $80,500, or $85,500 for premium finishes. The L10 operates in the current domain rather than voltage domain, achieving a signal-to-noise ratio of approximately 141dB that remains independent of volume level. It received a Stereophile review in early 2026 by Jason Victor Serinus, who described it among the reference line-stage preamplifiers currently in production.
The M10 is the 10 Series monoblock power amplifier — a two-chassis-per-side design (amplifier plus separate power supply). The M10 uses CH’s adjustable global-versus-local feedback and adjustable channel gain, along with circuitry designed to maintain constant bias regardless of room temperature.
The C10 is the 10 Series D/A processor — a twin-chassis DAC supporting DSD, MQA, and high-resolution PCM via CH’s proprietary CH-Link HD interface, plus modular digital and Ethernet control inputs. Reviewed by Jim Austin in Stereophile.
The P10 is the newest 10 Series component — a reference phono preamplifier that expands the 10 Series lineup, announced at Munich High End 2025.
The 1 Series is the foundation of the CH Precision line and remains in active production alongside the 10 Series. Products are entry points to the CH platform and share the same modular philosophy — most models offer multiple optional cards that add functionality without requiring a chassis replacement.
The I1 Universal Integrated Amplifier is CH’s most accessible entry point. The base configuration is priced around $38,000, with a fully-optioned unit — adding USB streaming, Ethernet streaming, an MC phono stage, and external clock synchronization — running toward the mid-$50,000s. Because the modular slots are designed to remain compatible across future generations, an I1 owner can specify the base unit initially and add modules over the ownership period as needs evolve, and, per CH’s own Raphael Pasche, a card such as the I1’s digital input board can later be transferred into a C1 rather than being discarded.
The A1.5 stereo power amplifier and M1.1 monoblock power amplifier sit above the I1 as separates-based amplification; a pair of M1.1s configured as monoblocks runs in the neighborhood of $100,000. Both feature adjustable global-versus-local feedback ratio — a signature CH design element that allows the owner to adjust the amplifier’s damping factor to better match specific loudspeakers and rooms. The A1.5 and M1.1 both support bi-amping configurations and can be operated with external power supplies for improved performance.
The L1 dual-mono line-stage preamplifier is the 1 Series preamp. Like the L10 above it, the L1 operates in the current domain rather than voltage domain. Multi-box configurations are supported: an L1 can be paired with a dedicated X1 external power supply for improved performance, or two L1s can be operated in dual-monaural configuration.
The P1 phono stage features CH’s current-sensing MC phono inputs — a design that eliminates the impedance-matching considerations of voltage-input phono stages and delivers superior signal-to-noise ratio for moving-coil cartridges. Multiple EQ curves are supported, including standard RIAA and various historical mono LP curves.
The C1.2 DAC/controller is the 1 Series digital hub. Supports CH-Link HD, S/PDIF, AES/EBU, TosLink, and modular inputs. Can be paired with the D1.5 CD/SACD transport for a complete CD/SACD source system, or used standalone with external streamers.
The D1.5 CD/SACD transport remains in production despite the general industry shift away from physical media — reflecting CH’s commitment to serving buyers who continue to build their systems around SACD and CD collections.
The X1 external power supply and T1 external clock generator are shared accessories that can be added to multiple 1 Series products for further performance improvements.
All CH Precision products use the CH-Link HD proprietary digital interface for connections between CH components. This is a within-brand feature; CH products also support standard AES/EBU, S/PDIF, TosLink, and asynchronous USB inputs for third-party connections.
This is the section that matters most for a buyer’s decision. CH Precision’s modularity is not a marketing category — it is a design commitment that shapes every product in the lineup and defines the ownership experience over the multi-year timeframe that most CH buyers are considering.
Every CH Precision product is designed around an internal card slot system. Functional blocks — digital inputs, USB inputs, streaming inputs, phono stages, clock synchronization circuits, additional analog inputs — are implemented as modular cards that fit into standardized slots in the main chassis. When a buyer orders a CH product, they specify which cards to include based on current system needs. The I1 illustrates the range of options: a factory-fitted digital input board is included in the base price, with USB, Ethernet streaming, MC phono, and clock-synchronization boards all available as add-ons. A base I1 can be expanded over time to add USB streaming, Ethernet streaming, phono, and external clock — all within the same chassis, all without requiring any chassis replacement.
More significantly, CH’s card slots are designed to remain compatible across product generations. When CH updates a product — the A1 became the A1.5, the M1 became the M1.1, the D1 became the D1.5, the C1 became the C1.2 — the card slots and their supported functionality are preserved where possible. This means the modularity is genuine rather than performative — the platform evolves without stranding existing owners.
CH also supports card transfers between products. In an I1 review, CH’s Raphael Pasche explained: “If you want to upgrade by adding CH’s C1 D/A controller, the I1’s digital input card can be transferred to the C1. You can evolve your system by adding other CH components without having to throw something away or trade it in.” This is a deliberate design choice that reflects CH’s view of ownership: the goal is a system that grows, not a series of trade-in cycles.
Related to but distinct from the modularity is CH’s adjustable feedback philosophy in the amplifier line. CH power amplifiers allow the owner to adjust the ratio of global to local feedback via the front-panel display. This changes the amplifier’s damping factor, which affects how the amplifier interacts with specific loudspeaker loads. Jason Victor Serinus described in his L10 review how a visitor inadvertently changed his feedback setting while fumbling with the front-panel controls, and the change was audible enough that Serinus knew something was different — but he couldn’t pinpoint what until Kevin Wolff visited to set up his M10 monoblocks and noticed the display indicator.
Adjustable feedback is an owner-facing feature, not a factory-only calibration. It means the amplifier’s character can be tuned to different systems, and it means an owner who changes speakers or moves rooms can adapt the amplifier’s behavior without requiring service or replacement.
CH maintains detailed build files for every product it has ever shipped, accessed via serial number. Each product’s serial number links to a factory record of its original configuration, its module history, any factory service events, and any upgrades performed. When a unit returns to Préverenges — whether for service, for CPO recertification, or for an upgrade to current specifications — the CH engineering team can access the full history. This is an unusually detailed level of production traceability for a small independent, and it is what makes the multi-generational upgrade path administratively workable.
A CH Precision product is not the sort of purchase that ages toward obsolescence. It is a purchase that ages toward configuration — as owners’ systems evolve, as their music sources shift, as new modules become available, as new displays and firmware are released. The buying decision is less “which specific product do I want in 2026” and more “which platform do I want to be on for the next fifteen years.” That reframing is genuinely different from how most high-end audio purchases work, and it is the single most important thing to understand about CH Precision before committing to the brand.
Beyond the modularity discussed in Section 4, CH Precision has established a distinct engineering signature across analog and digital domains. The design vocabulary reflects Cossy’s amplifier and analog background at Goldmund and Heeb’s digital software specialization at Anagram, combined and refined over more than fifteen years of collaborative product development.
CH’s L1 and L10 line-stage preamplifiers operate in the current domain rather than the voltage domain. In conventional line stages, volume control is implemented as an attenuator ahead of a fixed gain stage, which means turning the volume down pushes the signal closer to the noise floor. CH’s approach places gain after the volume control, so that the signal-to-noise ratio remains constant regardless of the volume setting. The L10 achieves approximately 141dB S/N ratio, independent of volume level — a specification that only makes sense in the context of current-mode operation.
The P1 phono stage uses current-sensing moving-coil inputs rather than voltage inputs. This eliminates the impedance-matching considerations that typically dominate MC cartridge system planning. The P1 also supports multiple historical EQ curves accessible via the front-panel display.
As discussed in Section 4, CH power amplifiers allow the owner to adjust the ratio of global to local feedback via a front-panel setting. Cossy has described the tradeoff directly: local feedback is usually more natural sounding because the feedback loop is shorter, while global feedback measures somewhat better. It is a signature CH design element that no other reference-tier amplifier offers in quite the same owner-adjustable form.
CH’s power amplifiers use patent-pending circuitry that monitors the operating temperature of each output transistor individually, keeping output-stage bias as constant as possible independent of ambient temperature or musical demand. Conventional amplifiers must either accept bias drift with temperature or use compensation circuits that themselves introduce artifacts.
Digital filtering technology designed by Thierry Heeb appears in every current CH digital product, and is also licensed to Wattson Audio (which CH owns) for use in Wattson’s Madison streamer.
CH uses discrete transistor circuits throughout the signal path — no op-amps in any critical audio position. Signal paths are fully differential (balanced) end-to-end. Cossy has stated that this “design from scratch” philosophy is applied selectively rather than dogmatically: “We use off-the-shelf products whenever we can. There is no point designing a new op-amp if there is a perfectly good op-amp already in production.”
CH’s circuit boards are built by a third-party Swiss manufacturer, while testing, additional processes, tuning, and final assembly are all performed in-house. Products are built in batches of up to six units at a time — the same “atelier tradition” that supports Swiss watchmaking. This distributed Swiss manufacturing model gives CH access to specialist capabilities without requiring the capital investment of vertical integration.
CH products use extensive software control for configuration, calibration, and operational parameters. An Ethernet Control board enables remote configuration and status monitoring via the CH Control app. Firmware is updated over the field to add functionality and refine behavior. This software-defined approach is central to the modular upgrade path — new module functionality can be enabled and integrated without hardware modifications to existing chassis.
CH Precision is one of the few high-end audio manufacturers whose product line is deliberately designed to work as an integrated system — while remaining fully compatible with third-party components at every interface.
Full-CH systems. At the entry tier, an I1 integrated amplifier with the appropriate modular options constitutes a complete CH front-end plus power amplifier in a single chassis. At the mid tier, a 1 Series separates system might combine an L1 preamplifier, a P1 phono stage, a C1.2 DAC/controller with a D1.5 transport, and an A1.5 or M1.1 power amplifier. At the reference tier, the 10 Series L10 preamplifier, C10 DAC, P10 phono stage, and M10 monoblocks form a complete reference system. Because all CH components use the CH-Link HD interface and share modular card compatibility, integration is straightforward.
Mixing CH with third-party components. CH products fully support standard interfaces: XLR balanced inputs and outputs, RCA single-ended, AES/EBU digital, S/PDIF, TosLink, and asynchronous USB. A CH preamplifier can drive a third-party power amplifier; a CH DAC can feed a third-party preamplifier. The proprietary CH-Link HD interface is a bonus for within-brand connections but never a required interface.
System evolution over time. The modular upgrade path applies not just within products but across the CH lineup. An owner starting with an I1 integrated amplifier can later add a C1.2 DAC as an external source, transferring the I1’s digital input card into the C1.2 rather than duplicating functionality. Owners upgrading from 1 Series to 10 Series can retain their existing 1 Series components as secondary systems or trade them in through CH’s Certified Pre-Owned program.
Loudspeaker matching. CH power amplifiers are designed to drive a wide range of loudspeakers. The adjustable global-versus-local feedback allows owners to tune the amplifier’s damping factor for their specific speakers — a feature particularly useful for owners who use unconventional loads (electrostatic panels, low-impedance dynamic speakers, high-impedance vintage designs). Specific pairing recommendations are best developed with an authorized CH dealer who can demonstrate multiple combinations in a controlled listening environment.
CH Precision’s warranty and support structure reflects both the reference-tier positioning and the modular upgrade philosophy that defines the brand.
Factory warranty. Standard factory warranty on new CH Precision products is two years, based on multiple current-market dealer listings. Specific transferability provisions for the factory warranty are not explicitly documented in any publicly available CH source located during our research. Prospective buyers — particularly used-market buyers — should verify current warranty terms and transferability with an authorized CH dealer or with CH Precision directly before purchase.
Certified Pre-Owned program. CH Precision operates a factory-backed Certified Pre-Owned program. CPO units are returned to the Préverenges factory in Switzerland for full inspection, bring-up to current production specifications, and recertification by the CH engineering team, with new displays installed where applicable. The serial number links to the product’s full factory build history, so every unit’s original configuration and service record is known.
How the CPO pipeline works. Sunny Components, a California CH authorized dealer, describes the process: units come from clients upgrading to the 10 Series, are shipped back to Switzerland through the dealer channel, spend time at the CH factory undergoing inspection and updates to current specifications, and return to the dealer for sale. Dealer-provided post-sale support is included in the CPO purchase. This is a middle path between private-party used purchase and new-product purchase.
Factory service. CH Precision handles all significant service at the Préverenges factory. Because CH maintains detailed build files linked by serial number, any product returning to the factory is diagnosed and repaired with full historical context. Dealer commentary notes that CH’s dealer support is unusually responsive — technical questions typically answered within 24-48 hours, and replacement boards for known issues shipped within a week where possible.
Distribution and dealer structure. CH Precision handles global distribution directly rather than through regional distributors. Kevin Wolff, CH’s Director of Global Sales, is based in the Seattle area and serves as the effective US point of contact for the CH dealer network and for reviewers. The US authorized dealer network is small and reflects CH’s positioning:
Additional authorized dealers exist across other US metros; CH Precision’s sales network page maintains the current authorized dealer list.
Support expectations. Because CH’s US dealer network is small, buyers outside major metros may find their nearest authorized CH dealer is a significant distance away. CH’s centralized factory service through Préverenges (with Wolff coordinating US-side logistics) means after-sale support does not require dealer proximity, but initial setup, extended demonstrations, and system-integration consulting benefit substantially from working with a dealer whose team is fully trained on the CH platform.
CH Precision electronics are designed for careful setup in system contexts where their capabilities can be fully realized. The reference-tier positioning implies a level of care in speaker matching, room acoustics, and system integration that matches the electronics’ capabilities.
Loudspeaker requirements. CH power amplifiers support a wide range of loudspeaker loads. The adjustable global-versus-local feedback allows owners to tune damping factor for specific speaker loads — useful for owners with electrostatic speakers, low-impedance dynamic speakers, or high-impedance vintage designs. Detailed speaker-amplifier matching recommendations are best developed with the authorized dealer during system setup.
Room considerations. CH products are used across a wide range of room sizes and acoustic contexts. Dedicated listening rooms with attention to acoustics represent the ideal context for realizing the electronics’ full capabilities.
System integration. CH’s modular platform means integration decisions are made not once at purchase time but continuously across the ownership period. New digital sources, streaming services, phono cartridges, or clock generators can be accommodated through card additions or module upgrades rather than component replacements. Owners should discuss anticipated system evolution with their dealer during initial planning so that appropriate module slots are specified up front.
Break-in and initial listening. CH products, like most reference-tier electronics, benefit from a break-in period of extended play before fully settling into their final voicing. Dealers typically deliver the equipment with meaningful hours already on it, but the first several weeks of ownership will reveal continued evolution of the sound.
Factory visits. CH Precision welcomes prospective and existing customers to visit the Préverenges facility. This is a legitimate and welcomed part of the CH customer experience for buyers at the reference tier. Contact CH directly or work with an authorized dealer to arrange.
CH Precision holds value on the used market relatively well, and the CPO program creates a genuine middle path for buyers looking for a factory-backed used purchase.
New purchase advantages. Full factory warranty, ability to specify exact module configuration at order time, dealer setup and delivery support, the latest hardware revision level with current displays and firmware, and direct dealer relationship for post-sale support.
CPO advantages. Factory-inspected, factory-recertified, brought up to current production specifications including new displays where applicable. CPO pricing is typically substantially below new pricing while retaining most of the value guarantees of a new purchase. CPO units are limited in supply — they come from clients upgrading to the 10 Series, so availability depends on trade-in flow.
Private-party used purchase. Efficient and cost-effective for buyers comfortable with pre-purchase inspection. Key items to verify before purchase: the original invoice from an authorized CH dealer, the serial number matching the invoice, complete module inventory including any factory-installed cards, verification of firmware and display revision level, and any factory service history. CH’s serial-number-linked build file system means this verification is administratively straightforward.
Modular status considerations. For CH products specifically, a key used-market consideration is the module configuration of the specific unit. A base I1 is a different product from a fully-optioned I1 with streaming, phono, and clock-sync modules installed. Verify with the seller which modules are installed and factor the module value into pricing comparisons.
Firmware and display revision. CH products have received firmware updates and hardware revisions over their production life. A used unit at an earlier revision level may be eligible for factory bring-up to current specifications through the CPO pipeline, potentially through the buyer’s authorized dealer.
Shipping considerations. CH Precision electronics are heavy and delicate. 10 Series dual-chassis products in particular are substantial. Private-party purchases at any significant distance require freight shipping through a specialist carrier or personal transport.
How CH holds value. CH Precision products retain value on the used market relatively well by high-end audio standards, reflecting the brand’s boutique positioning, the modular upgrade philosophy that keeps older units serviceable and current-spec-updatable, and the factory CPO program that provides an alternative distribution pathway for trade-in units. Used-market comparisons through platforms with Sold Comps data (including HiFi Registry) are the most direct way to establish current market value for a specific configuration.
CH Precision occupies a specific position within the high-end audio landscape. Understanding its neighbors helps clarify which buyers should be looking at CH Precision versus alternatives.
Vs. dCS. Both CH Precision and dCS are reference-tier digital-focused brands with significant analog expertise. dCS is primarily digital (DAC, streamer, upsampler); CH Precision offers a fuller lineup covering both digital and analog. Buyers who want a single-brand system covering both digital sources and amplification will find CH’s fuller lineup more accommodating.
Vs. Boulder Amplifiers. Boulder is the closest US analog to CH Precision — an independent high-end brand with reference-tier amplification and preamplification, deep engineering focus, and a modular platform philosophy. Direct comparison at authorized dealers of both brands is the correct evaluation path.
Vs. Soulution. Also Swiss, also reference-tier, also engineering-focused, and founded by other Goldmund alumni. Both use Swiss precision manufacturing and target very demanding buyers. Different sonic signatures and different design philosophies; direct listening comparison is essential.
Vs. Goldmund. Given that Cossy and Heeb both came from Goldmund, the comparison is direct and personal. Goldmund continues to operate under its own leadership and produces its own reference-tier products. Buyers considering both should audition both — the design vocabulary shares roots but has diverged substantially over the intervening decades.
Vs. FM Acoustics. Another Swiss independent, also reference-tier, also with a strong engineering focus. FM Acoustics represents a different corner of Swiss high-end audio and is worth including in the audition list for buyers seeking specifically Swiss-designed electronics.
Vs. MSB Technology, Wadax, Aurender, Esoteric. These brands share reference-tier positioning in various source and system contexts. Direct comparison at dealers with capable listening environments is the appropriate evaluation path for buyers considering the reference tier broadly rather than committing to CH specifically.
CH Precision products are engineered for multi-decade ownership. The modular platform, the detailed build-file continuity, the factory service pathway, and the ongoing hardware and firmware updates all point in the same direction: CH’s design philosophy assumes owners will keep their products for many years.
Module upgrades over ownership period. New modules for existing products are periodically released by CH. Owners can add modules as their systems evolve — new streaming standards, new digital source technologies, new phono equalization needs. The card slot compatibility means these additions do not require chassis replacement.
Firmware updates. CH Precision products receive firmware updates over their production life. These updates refine behavior, add features to existing modules, improve stability, and occasionally add new functionality. Firmware updates are typically field-installable via the Ethernet Control interface.
Hardware revisions and factory bring-up. CH periodically updates hardware components — new displays, updated internal boards — that improve product behavior. Owners can send products to the factory (through their authorized dealer) for bring-up to current hardware specifications.
Long-term parts and service commitment. Because CH has produced a small and stable product family since 2010, the parts inventory and service documentation remain manageable. The retirement of the A1 (replaced by A1.5) is the only significant end-of-life event across CH’s history. Owners of current-lineup products can reasonably expect long-term serviceability.
Resale. CH Precision products retain value on the used market well, as discussed in Section 9. The CPO program provides an active resale pathway for owners upgrading within the CH lineup.
CH Precision is the correct choice for buyers who:
CH Precision may not be the right choice for buyers who:
The final evaluation is best done at an authorized CH Precision dealer with the buyer’s own music and, if possible, with the buyer’s own amplifier or other electronics for direct A/B comparison. CH’s presentation is distinctive enough that a short audition at a busy audio show or in a mismatched system produces misleading impressions in either direction.
For pre-owned CH Precision purchases through HiFi Registry or comparable marketplaces, the guidance is straightforward: verify the unit’s serial number and complete module configuration with CH Precision or an authorized dealer before purchase, understand whether the unit is at current firmware and hardware revision, factor freight shipping into total-cost calculations for reference-tier products, and consider whether the CPO pipeline offers a better value proposition than private-party purchase for the specific product you’re targeting. CH’s modular platform and detailed build-file continuity make used-market purchases substantially more transparent than most reference-tier brands.
CH Precision was founded in 2009 by Florian Cossy and Thierry Heeb and remains independently owned. Florian Cossy continues as CEO. Thierry Heeb, who specialized in digital filtering and processing, passed away on July 22, 2024; the company has continued under Cossy and its engineering team. CH Precision has undergone no corporate transitions or acquisitions since its founding.
All CH Precision products are designed, tested, tuned, and finally assembled at the company's facility in Préverenges, Switzerland, just west of Lausanne. Chassis boards are built by a third-party Swiss manufacturer, but testing, tuning, and final assembly are performed in-house, with products built in batches of up to six at a time.
Standard factory warranty on new CH Precision products is two years per current dealer listings. Specific transferability provisions are not publicly documented; verify current warranty terms with an authorized dealer or CH Precision directly, particularly for used-market purchases.
Yes. CH Precision operates a factory CPO program in which units are returned to Switzerland, inspected, brought up to current production specifications, and recertified. CPO inventory comes from clients upgrading to the 10 Series. CH's dealer network reports technical support response times of 24-48 hours and replacement boards typically shipped within a week.
CH Precision handles global distribution directly. Kevin Wolff, Director of Global Sales, is based in the Seattle area and serves as the primary US point of contact. The US authorized dealer network is small and includes dealers such as Liquid HiFi (Charlotte, NC / Indian Land, SC), Definitive Audio (Seattle), Sunny Components (Covina, CA), and Audio Ultra.
The 1 Series is CH Precision's foundation lineup (I1, A1.5, M1.1, L1, P1, C1.2, D1.5, T1, X1). The 10 Series is the reference tier (L10, M10, C10, P10), using the same modular architecture but with dual-chassis topology, reworked PCB layouts, and elevated component selection.
Yes. CH Precision's modular card-cage architecture allows most products to receive new optional modules over their ownership period. Hardware bring-up to current production specifications is also available through the factory via authorized dealers, and cards can often be transferred between products as a system evolves.
CH power amplifiers feature owner-adjustable global-versus-local feedback ratio via the front-panel display, which changes the amplifier’s damping factor and allows tuning for specific loudspeaker loads. The M10 additionally uses patented circuitry designed to maintain constant output-stage bias independent of ambient temperature.
CH Precision distributes through a small, boutique network of authorized specialist retailers coordinated directly by CH’s Director of Global Sales. Authorized-dealer status matters with CH because factory warranty coverage and CPO service coordination go through that same dealer channel.
