Every category of high-end audio has three prices worth knowing: what the manufacturer set at launch, what it sold for last week, and what it's worth right now given both. HiFi Registry Listing Comps track the market side — real asking prices from real listings across the used-audio market, and, going forward, real HFR sold prices. For anyone. For free.
For sellers, it's a pricing anchor that isn't a coin flip. For buyers, it's a way to know if the ask is fair before you send a DM. For the market itself, it's a shared reference — grounded in real listings and completed sales, not in what any single seller wishes their piece were worth.
Here's how it's built, where the data comes from, and why it's free — permanently.
Two sources, handled differently.
Listing prices are aggregated from real listings across hundreds of datasources going back years — high-end audio marketplaces, specialist dealer sites, classified sections of audio publications, and enthusiast venues. Both current listings and closed-but-recent listings feed the record.
The compilation runs through a combination of multiple advanced frontier-model AI search methodologies across those sources, then normalizes what it finds through AI-assisted parsing that disambiguates brand names, unifies model variants (integrated vs. separates, standard vs. anniversary, regional voltage variants), preserves condition and currency context, and filters out non-audio noise.
Sold prices are recorded from completed transactions on HiFi Registry itself.
Both feed the same brand+model rows. Listing data tells you what the market is asking. Sold data tells you what the market has paid.
The Registry opened for business on July 1, 2026. Before that date, HFR had no completed transactions of its own to record.
Rather than back-fill with unverified sold-price data from other platforms — which the Registry cannot audit for accuracy, completeness, or whether the sale actually closed — anything dated before July 1, 2026 is presented as listing data only, and is explicitly labeled as such.
Listing data reflects what sellers were asking. It does not claim to be what pieces actually sold for.
As of July 1, 2026 and going forward, sold prices come only from completed transactions on HiFi Registry. Every one is verified, dated, condition-noted, and attributable to a real closed sale.
Over time, the balance shifts. Every completed sale on the Registry adds a data point. The pre-July-2026 listing-only band becomes historical context. The sold-price record becomes the ground truth.
It means every price you see was pulled from a real listing on a real marketplace, posted by a real seller offering a real piece of gear. Not:
If Listing Comps show a range for a piece of gear, that range came from listings the Registry can point to. If the coverage is thin — a rare piece, a niche brand — the record shows that thinness rather than manufacturing a confident-looking number from nothing.
Two things.
Access. Other companies' bluebook services paywall their data behind subscription tiers — some at consumer subscription rates, some at professional-appraiser pricing. Access to a piece of gear's history costs money, regardless of whether you're buying, selling, or just curious about a piece you own.
HiFi Registry Listing Comps are free. Anyone can look up any brand and model. Now, and permanently — this is not a launch promotion or a limited feature.
Provenance. Legacy bluebooks collect data from a mix of dealer surveys, historical transaction records, and their own opinions. The methodology is closed. HiFi Registry Listing Comps are explicit about what the numbers are built from: real listings compiled from hundreds of active datasources across the high-end audio market, and — for sold prices — completed HFR transactions.
A transparent record is worth more than a comprehensive one that won't explain itself.
Yes. Listing Comps are free forever. That's a commitment, not a marketing line.
The Registry's revenue model is flat listing fees: $25 for equipment and dealer listings, $5 for music media. Wanted ads and the forum are free.
Paywalling Listing Comps would be self-defeating. The Registry's value proposition is that both buyers and sellers can make informed decisions. Charging for the reference data that lets them do that would reintroduce exactly the friction the platform is designed to remove.
Paid bluebook services in this space treat market data as a commodity to be sold. HFR treats it as infrastructure the community needs to function honestly.
Listing data refreshes as new listings appear across the source datasources and old ones close.
Sold data is added shortly after a Registry transaction completes.
The current release covers most major high-end audio manufacturers across categories: separates (amplifiers, preamps, phono stages), DACs, transports, turntables, tonearms, cartridges, speakers, headphones, cables, and select vintage gear.
The catalog grows on two axes: new brands are added as they surface in listing data, and new models within existing brands are added as they appear.
If your gear isn't in Listing Comps when you search, email support@hifiregistry.com — additions typically appear within a day.
Tell us. Common valid reports: brand or model incorrectly identified, condition tier mismatched, unit variant not distinguished from another (100V vs 240V, standard vs signature vs anniversary), regional pricing collapsed inaccurately, or a listing captured that clearly doesn't reflect the market.
Email support@hifiregistry.com with what's wrong. Reports go to a human. Verified corrections update the record. Chronic bad-faith reporting is deprioritized on discovery.
Listing Comps are not an oracle — they're a summary of what the market has paid and what the market is asking. When they're wrong, we want to know.
Listing data: real listings from hundreds of high-end audio marketplaces, dealer sites, and specialist publications, going back years.
