  • Description

    The Classic 60 Hybrid Stereo Power Amplifier resembles the long-popular D115 in Audio Researchs family of High Definition® power amplifiers. But its lineage is strictly Classic 150. Which means nothing less than state-of-the-art in design, construction, musicality, and operational convenience...at an affordable price. Like the Classic 150, the Classic 60 proceeds from the notion that power ratings dont always describe a power amplifiers real capabilities. Far more important are such qualities as dynamic stability. lucidity, subtlety. And to achieve those, Audio Research has used its traditional partial cathode coupling along with triode operation of the Classic 60s eight 6550 power output tubes. Additional circuit improvements, as well as the usual rigorous parts selection and manufacturing Audio Research, are noted for, also contributing sonically. Translated into the language of listening, this signifies stunning bandwidth, a noise floor virtually beneath audibility, and musically fulfilling SPLs at dramatically lower gain settings. Dynamics, timbres of individual instruments, soundstage, and musical emotion all surge out from a black velvet of silence. Simply put the Classic 60 resolves far more of a musical program than amplifiers rated at two, three, or four times its seemingly modest 60 WPC. But the Classic 60 is easily up to the task of driving all but the most demanding loudspeakers, even in spacious listening rooms. And while it shows modest preamplifiers in their best light, it also shines when coupled with premiere designs, such as Audio Researchs SP14 or SP15. Convenience figures are high on the Classic 60s list of attributes, as well. For example, the DC balance of the output tubes is maintained automatically, while tube biasing continuously adjusts to changes in incoming line voltage. Performance stays razor-sharp without bothersome tweaking or adjustments. And quiet fan cooling, along with triode operation, means significantly longer tube life. A Classic 60 owner can look forward to years of low-maintenance performance POWER OUTPUT60 watts minimum continuous at 16 ohms from 15Hz to 20kHz with less than 1.0% total harmonic distortion. Typically below .005% at 1 watt. The approximate actual power available at clipping: 62 watts.

    For your consideration is one of my audio treasures: the classic and strikingly awesome Audio Research SP-10 (Revision 6 - sometimes called MK II but not designated). I want to say that I will regret selling this but circumstances beyond my control dictate otherwise. The units are in mint condition. I have had these for years and always have babied it. (I own two pairs). This one hardly has been played. All tubes test strong and are Russian tubes as tested by Audio Research. You will be buying a legend for less than the money when new. In todays inflationary economy this preamp from Audio Research would cost $10,400.00 The condition is as you would expect from a one owner very limited use component. Not a scratch or blemish anywhere, entirely without issues. You do not see SP-10s in this kind of condition every day. I have packing appropriate for these units and all will be done correctly. Tubes will be packed separately in the right ARC containers. International bidders welcome. Shipping will be done via eBay International Shipping.

    ATTENTION! This auction is for AUDIO RESEARCH PREAMPLIFIER SP 14 ONLY!!!!! If you want to by extra AUDIO RESEARCH CLASSIC 60 - See My other auctions. The SP14s musicality comes surprisingly close to the state of the art, with soundstage of remarkable depth and breadth; imaging of uncanny solidity: palpable dynamic authority; timbral accuracy that virtually recreates live music; an exceptionally low noise floor; and a special ease with frequency extremes. But unlike many high-performance preamplifiers, the SP14 doesnt scrimp on control features. It has separate Gain and Attenuation for wide-ranging-yet-subtle level management. Separate Input and Record Output selectors (with a common menu) permit exceptional flexibility in playing and recording: owners can listen to one source while recording from another. The Bypass switch allows owners to remove the Balance and Mode controls from the signal path, for greater sonic purity. There are two separate sets of outputs, and three power outlets. And, of course, the SP14 features its own version of the hybrid technology that has made Audio Research electronics world-famous. As with every Audio Research product, SP14 parts quality, construction and factory support are the finest in the audio industry, with a two-decade track record to prove it. And all this comes at only half the cost of the celebrated SP15. FREQUENCY RESPONSEHigh-level section: ±.5dB, 5Hz to 50kHz, -3db points below 1Hz and above 200 kHz.

Translated into the language of listening, this signifies stunning bandwidth, a noise floor virtually beneath audibility, and musically fulfilling SPLs at dramatically lower gain settings. Dynamics, timbres of individual instruments, soundstage, and musical emotion all surge out from a black velvet of silence. Simply put the Classic 60 resolves far more of a musical program than amplifiers rated at two, three, or four times its seemingly modest 60 WPC. But the Classic 60 is easily up to the task of driving all but the most demanding loudspeakers, even in spacious listening rooms. And while it shows modest preamplifiers in their best light, it also shines when coupled with premiere designs, such as Audio Researchs SP14 or SP15. Convenience figures are high on the Classic 60s list of attributes, as well. For example, the DC balance of the output tubes is maintained automatically, while tube biasing continuously adjusts to changes in incoming line voltage. Performance stays razor-sharp without bothersome tweaking or adjustments. And quiet fan cooling, along with triode operation, means significantly longer tube life. A Classic 60 owner can look forward to years of low-maintenance performance POWER OUTPUT60 watts minimum continuous at 16 ohms from 15Hz to 20kHz with less than 1.0% total harmonic distortion.

    Audio Research SP9 Tube preamplifier Super Clean mint condition, Working perfectly, including phono input MADE IN USA The SP9 Hybrid Stereo Preamplifier represents a further evolution of the innovative electronic design first embodied in the widely acclaimed Audio Research SP11 Stereo Preamplifier. The SP9 is not a stripped-down version of the SP11, but rather represents an adaptation of some of the SP11s patented hybrid technology to a simpler, more economical single-chassis format.Using just two 6DJ8 vacuum tubes (one in the phono section and one in the high-level stage) in intermediary gain stages, the SP9 expresses the musicality and natural rightness vacuum-tube preamplifiers have been noted for, yet it does so with the quickness and dynamic vigor of the best solid-state designs.Because its two vacuum tubes are used so conservatively, the SP9 will undoubtedly prove to be one of the most reliable and lowmaintenance Audio Research preamps ever up to 10,000 hours of service life are possible before replacement of these tubes might be necessary. And, replacement tubes are not required to be select, low-noise (and expensive) types. Audio Research brand vacuum tubes obtained from your authorized dealer will provide the best performance and reliability.Although the SP9 contains an on-board power supply (as opposed to the SP11s isolated supply), it is a highly advanced, tightly regulated design employing a shielded toroidal power transformer to minimize any potential problems of mechanical noise or hum. Location of this transformer in relation to special low-hum input circuitry has been optimized within the SP9 chassis layout to virtually eliminate transformer-related noise. (Note that while outboard power supplies have become a popular design trend among high-end audio manufacturers, simply isolating the power supply from the main chassis has little benefit if the basic design of the supply itself is second-rate. In such cases, outboard isolation may be little more than a cosmetic cure for more serious deficiencies.)While the SP9 is designed to provide superb playback from phono records, its high-level circuits have also been optimized for other popular input sources, including compact discs. In this respect, the SP9 is virtually overloadproof, insuring maximum enjoyment of todays most dynamic program material. And, with two tape monitor loops, the SP9 offers the tapedubbing flexibility so many listeners want but seldom find in an audiophile-grade preamplifier.Of course, all controls and switches used in the SP9 have been carefully specified and selected to insure minimal sonic degradation - as have the other active and passive components used in the construction of the SP9. While the SP9 is more affordable than some other Audio Research preamplifiers, its more modest price was not achieved at the sacrifice of component quality. Careful, elegant design, structural simplicity and efficient manufacturing techniques have all contributed to a standard of physical integrity and musical accuracy never before achieved in this price class.To audition the SP9 Stereo Preamplifier, visit your authorized Audio Research dealer.

    ATTENTION! This auction is for AUDIO RESEARCH PREAMPLIFIER SP 14 ONLY!!!!! If you want to by extra AUDIO RESEARCH CLASSIC 60 - See My other auctions. The SP14s musicality comes surprisingly close to the state of the art, with soundstage of remarkable depth and breadth; imaging of uncanny solidity: palpable dynamic authority; timbral accuracy that virtually recreates live music; an exceptionally low noise floor; and a special ease with frequency extremes. But unlike many high-performance preamplifiers, the SP14 doesnt scrimp on control features. It has separate Gain and Attenuation for wide-ranging-yet-subtle level management. Separate Input and Record Output selectors (with a common menu) permit exceptional flexibility in playing and recording: owners can listen to one source while recording from another. The Bypass switch allows owners to remove the Balance and Mode controls from the signal path, for greater sonic purity. There are two separate sets of outputs, and three power outlets. And, of course, the SP14 features its own version of the hybrid technology that has made Audio Research electronics world-famous. As with every Audio Research product, SP14 parts quality, construction and factory support are the finest in the audio industry, with a two-decade track record to prove it. And all this comes at only half the cost of the celebrated SP15. FREQUENCY RESPONSEHigh-level section: ±.5dB, 5Hz to 50kHz, -3db points below 1Hz and above 200 kHz.

    ATTENTION! This auction is for AUDIO RESEARCH AMPLIFIER CLASSIC 60 ONLY!!!!! See My other auctions.The new Classic 60 Hybrid Stereo Power Amplifier resembles the long-popular D115 in Audio Researchs family of High Definition® power amplifiers. But its lineage is strictly Classic 150. Which means nothing less than state-of-the-art in design, construction, musicality, and operational convenience...at an affordable price. Like the Classic 150, the Classic 60 proceeds from the notion that power ratings dont always describe a power amplifiers real capabilities. Far more important are such qualities as dynamic stability. lucidity, subtlety.

Fully tested and found to be in good working condition. All inputs and outputs teste (well except for XLR connections) and all are in good working order. Nice clean sound, no noise, no static or distortion. Yes, I also tested PHONO input and that is working well. All switches work well. Volume is smooth without static. Input selector is also smooth and without noise. All lights work. Includes original remote which is also in good working condition. There was a small amount of battery leak corrosion in the battery compartment which I manages to clean and now it makes good contact with batteries. I guarantee you will receive this item in as pictured and described condition. Im a hifi enthusiast myself and know how to test equipment and what to look for. So this is not just coming straight from the thrift store to your home. It is straight from the home of an audiophile who took care of his equipment very well.

    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.
