McIntosh MC302

McIntosh MC302: used price, how it differs from the MC312, and what to check before you buy

By HiFi Registry Staff · Published November 1, 2026

In short: The MC302 is the 300 watt per channel solid-state stereo amplifier McIntosh built from 2010 to 2018, with an output autoformer on each channel so the full rating holds into 2, 4 or 8 ohms. It launched at $5,500, listed at $7,000 by the end of its run, and was replaced by the MC312 in October 2018. Dealer-certified used examples have sold at $4,299 and private asking prices in late 2025 ran from $3,500 to about $4,500, roughly $1,000 to $1,500 under a used MC312. Every MC302 is now outside McIntosh's three year warranty. HiFi Registry's recorded sales for this model are in the table further down the page. Prices checked November 1, 2026.

Lineage: MC352 to MC302 to MC312

There is one version of the MC302. The decision on the used market is between it and the amps on either side of it in McIntosh's 300 watt class.

Source: McIntosh's legacy pages, the MC312 product page, the 2010 and 2018 launch announcements and the MC302 owner's manual. Autoformers, Power Guard, Sentry Monitor and Power Control carry across every model in the table.

Specs that matter

• 300 watts per channel into 2, 4 or 8 ohms, 20 Hz to 20 kHz, 0.005 percent THD from 250 milliwatts to rated power
• Dynamic headroom 1.8 dB; wideband damping factor above 40; signal to noise 95 dB balanced and 93 dB unbalanced, A-weighted (120 dB and 118 dB below rated output)
• Push-pull solid-state output stage with ThermalTrak transistors, which carry a temperature sensor in the package so bias tracks heat directly. Not Quad Balanced: McIntosh used that term for the MC452 in the same 2010 announcement, and the MC312 that replaced the MC302 is specified as push-pull complementary
• One output autoformer per channel in potted aluminum enclosures; speaker taps for 2, 4 and 8 ohms
• Power Guard clipping protection, Sentry Monitor fuseless short-circuit protection, thermal protection
• Inputs: one balanced XLR and one unbalanced RCA per channel, selected by a rear panel switch. Input impedance 22 kohm either way. No signal outputs of any kind
• Mono bridge: no. Mono parallel: no. The manual has no mono mode
• Power supply: a 28 lb potted transformer and two main filter capacitors storing more than 140 joules. Convection cooled, no fans
• Front panel lit by LEDs through fiber optic diffusers; meter lights can be switched off; Power Control in and two outs; auto off after about 30 minutes without signal
• 98 lb (44.5 kg) net, 131 lb shipping; 17.5 x 9.44 x 22 inches including feet, knobs and cables
• US list: $5,500 at launch in October 2010, $7,000 by the end of production per dealer listings
• Warranty: 3 years from purchase, original owner only, terminates on transfer, valid only on units bought from an authorized McIntosh dealer in the US or Canada

The one bench test we found is the Italian magazine Suono's September 2012 review, hosted on McIntosh's MC302 legacy page. Suono measured 385 watts into 8 ohms at 0.3 percent THD+N before Power Guard stepped in, and found the frequency response almost unaffected by load on any of the three taps. Owner reports on Audiogon split on character: one listener found it too warm next to a Krell, another heard no warmth at all through a McIntosh tube preamp.

Used prices

HiFi Registry's recorded sales for the MC302 are in the table below this guide. What the wider market shows, as of this writing:

• Dealer certified pre-owned, US: TMR Audio has sold two cosmetic 8 examples with factory packaging at $4,299, both quoting a $7,000 MSRP, and a cosmetic 7 example at an unshown price. Its current listing, a one-owner amp 15 years or older with marks on the top and discolored speaker terminals, is asking $5,099 plus $399 freight. SkyFi Audio has sold several but does not show prices on closed listings.
• Private asking, US: US Audio Mart listings between October and December 2025 asked $3,500, $3,750, $3,900 and $4,533, the last for a one-owner example described as mint.
• Overseas asking prices: EUR 5,300 in Italy, DKK 39,000 to 44,000 in Denmark. European list was far higher than US (Suono quoted EUR 8,400 in 2012), so do not read these across.

Expect a private US sale to land between $3,500 and $4,500 for a clean, complete example with packaging, and dealer certified stock around $4,300 to $5,000. That is 60 to 70 percent of the $7,000 final list. Against the MC312, where TMR has sold at $4,999 and is asking around $6,100, the MC302 saves roughly $1,000 to $1,500 for the same rated power.

What to check before buying

1. Shipping is the first risk. The MC302 ships at 131 lb. Insist on the original factory carton and a freight carrier, or buy local. TMR has charged $135 to $399 to ship one within the lower 48.
2. Front glass and faceplate. Look for chips at the corners and scratches around the handles. McIntosh excludes glass from warranty even when it applies, and no MC302 is under warranty now.
3. Fiber optic lighting. The MC302 lights its glass with LEDs through fiber optic diffusers, not incandescent bulbs, so the panel should not have dimmed with age. Uneven brightness or one meter darker than the other is a fault, not wear.
4. Meters. Confirm both meters track together on a mono signal and that Hold mode locks and slowly releases. The meter light switch should kill the illumination completely.
5. All three speaker taps. Check output on the 2, 4 and 8 ohm taps on both channels. The posts lock with a quarter turn and the manual warns against over-tightening. Discolored terminals, noted on TMR's current listing, are cosmetic.
6. Heatsink fins and top cover. The side-mounted heatsinks and the chassis top are where every dealer listing we found reports scuffs. Harmless, but price them in.
7. Protection circuits. Power Guard should light only on hard clipping. An amp that trips Sentry Monitor at normal levels has a fault, and the ThermalTrak bias is not a user adjustment.
8. Capacitors and service. The newest MC302 is eight years old and the oldest sixteen. We found no pattern of failures in owner forums, but ask whether the amp has been serviced and by whom. Work on an autoformer McIntosh belongs with McIntosh or an authorized service agency.
9. Auto off. The amp shuts itself off about 30 minutes after the signal stops when no Power Control cable is connected. A seller who says it "turns itself off" is describing a feature.
10. Do not plan on bridging or pass-through. There is no mono mode and no line-level output. If you need to feed a subwoofer or a second amp, you want the MC312.

Who it is for, and what else to consider

The MC302 is for someone who wants a full-size McIntosh stereo amp with the blue meters and autoformers and has decided that 0.5 dB of headroom and a pair of pass-through outputs are not worth the MC312 premium. On moderately demanding floorstanders in a normal room it is the same 300 watt autoformer amplifier, and Suono's bench numbers show it clearing its rating before Power Guard intervenes.

If you need more than 300 watts, the MC452 (450 watts, Quad Balanced) shares the MC302's chassis and era, and the older MC402 is the 400 watt Double Balanced design it succeeded. If you need less, the MC152 at 150 watts is the smallest amp in the family. McIntosh's brochure named the C48 preamp as the MC302's companion, and HiFi Review tested it with the C47 in 2016. Buyers who want a tube front end usually pair it with a C2500 or C2600.

Frequently asked questions

What is a used McIntosh MC302 worth? Dealer-certified examples in the US have sold at $4,299, and private listings in late 2025 asked $3,500 to $4,533. Expect $3,500 to $4,500 for a clean private sale with packaging; see the recorded sales table for what has actually changed hands on HiFi Registry.

When was the MC302 made and what did it cost? McIntosh lists production as 2010 to 2018. It was announced October 6, 2010 at $5,500 and shipped that month. Dealer listings for late production units quote a $7,000 list, the same figure the MC312 launched at when it replaced the MC302 in October 2018.

What is the difference between the MC302 and MC312? Same 300 watt rating and autoformer output. The MC312 doubled the filter capacitance, which lifts dynamic headroom from 1.8 dB to 2.3 dB, and added direct LED backlighting in place of the MC302's fiber optic system, upgraded wiring and components, new autoformer enclosures, Monogrammed Heatsinks, eco power management and balanced and unbalanced pass-through outputs.

Can the MC302 be bridged to mono? No. The owner's manual has no mono mode, and McIntosh lists mono bridge and mono parallel as unsupported on the MC312 as well. The MC352 of 1998 to 2004 was the last amp in this class with a 700 watt single-channel mode.

Is the MC302 Quad Balanced? No. McIntosh applied that term to the MC452 announced alongside it. Suono's 2012 test lists the MC302 output stage as push-pull, and the MC312 that replaced it is specified as push-pull complementary.

How heavy is the MC302? 98 lb (44.5 kg) out of the box, 131 lb in the shipping carton. It is a two-person lift.

Is a used MC302 still under warranty? No. McIntosh's three year warranty covers the original purchaser only and ends on transfer, and production stopped in 2018, so every MC302 on the used market is out of coverage regardless of condition.
