  • 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.

    Audio Research VSi60 integrated amplifier in excellent condition. I purchased it gently used 7 years ago with about 100 hours of use on the tubes according to the previous owner. I put an additional 100 hours into them and really, really enjoyed every bit of audio I ever put through this machine. However, when I moved to NYC a little over 5 years ago, I had to consolidate a lot of my audiovisual equipment into a single room instead of having the luxury of dedicated audio space...so this unit has sat safely in storage within my apartment for the past 5 years or so. Despite what on its face may seem like a fairly modest output power (50Wpc), this integrated amp REALLY excels with low impedance speakers and is a very handsome centerpiece for an audio setup that doesnt have unlimited cabinet space for a more complex setup. Stereophile and several other outlets still have their pre-release reviews published online if youd like more information about how they perform. This unit will come with its original remote (as pictured), its original users manual, and will ship in its very secure original box. It will come with the included extra fuses as well as all of its tubes in an additionally lined and secured box inside. I was holding out hope that my situation might change over the past 5 years and I would be able to justify setting this up again—especially since units like these come on the secondary market less and less every year, and tubes havent gotten easier to replace in more thoroughly used units in the future—but at this point I really want someone else to enjoy this instead of having it go unappreciated in storage. Im setting a fixed rate for shipping within the lower 48 and will cover anything above that cost myself. If you happen to live within a short distance from NYC such that ground shipping rates would be much less than the fixed rate in the posting, we can sort out a discount through the offers system. Feel free to reach out with any questions.

    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.
