The worlds largest online retailer of pre-owned audio Product DescriptionWho we areWhat we doOur ProcessOur Policies Audio Research Reference 160M Mono Tube Power Amplifier; Monoblock Pair; REF160M Product SKU: 54758 Age: 2 years Tobacco Exposure: No MSRP: $30000 Voltage: 120V # of Owners: 1 Service History: None Cosmetic Description: Very good condition with minimal visible cosmetic wear including very minor scuffing on the top surface of both amplifiers. What is Included: Pair of amplifiers, Four Tung Sol KT150 tubes, Four Sovtek 6H30Pi tubes, Manuals, Two Power cables, Factory packaging Other Notes: Tubes test very well. Tube hours unknown. 160M offers things I’ve never heard before from an ARC amp: a newfound control that makes for “higher definition” from top to bottom; a standard-settingly low noise floor; a naturally richer and more neutral tonal palette; a naturally fuller power range; somewhat better focused and less midrange-forward imaging; and an even-handed presentation of the dynamic/harmonic envelope that no other amplifier I’m familiar with can better. -Jonathan Valin, The Absolute Sound Functional Notes: Operational condition of this item is excellent, fully tested and no issues found.

Up for sale is a properly working and clean Audio Research Classic 60 tube power amp. It came to us in working shape and we played music on it for several hours without any problems. Tube Complement: (8) 6550 outputs 7) Philips/ECG and 1) Sovtek (4) 6CG7 drivers All Philips/ECG Only issues, both of which we consider small: >One of the two fans is slightly noisy. >On our fancy test equipment it puts out just over 40 watts per channel, not the 60 its supposed to. A friend loaned us some new Sovteks and it easily put out 60 watts/channel on our Sound Technology Test Panel. So to get it to spec it needs 8 new output tubes but it works just fine as it is. Serial number 99046002 If prepaid we will offer curbside pick-up in Central Berkeley or well deliver it within 50 miles (each way) from us in Berkeley. If shipped it will be very well packed and we promise it will arrive working and exactly as described. No long term guarantee beyond that. Shipping to the USA only unless youre using eBay Global Shipping program. The Sound Well has been selling Vintage Home Stereo Components in Berkeley since 1974 under mostly same ownership. Local pick up in Berkeley is fine if prepaid. Since were now operating without a storefront we are unable to offer audition of the piece. Note that eBay is now collecting sales tax for the state of the buyer where applicable. FedEx only if shipped. Thanks very much for looking.
