    In excellent condition. May have some shelf wear such as dust, etc. Used only a handful of times, and has been stored since. Tested and working amazingly. Some scratches on top or marks throughout as expected due to age and light use. One original owner. Do not miss out on this rare opportunity to own this rare machine! *The testing was to the extent that it turns on, and fires up correctly. Didn’t have a system to test it on beyond that. * Rare users manuals also included. This enhances the sound amazingly! Thank you for looking and happy shopping!

    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 AMPLIFIER CLASSIC 60 ONLY!!!!! If you want to by extra AUDIO RESEARCH PREAMPLIFIER SP-14 - 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. 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.

    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. 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.
