Audio Research now
proudly introduces the Classic, new , moderately priced
stereo hybrid amplifiers that come surprisingly close to the benchmark set by
the acclaimed Classic 150 hybrid monaural amplifier.
It doesen't take a
"golden ear" to immediately perceive the emotinal power and sonic
authority the Classic 60 bring to any good musical program. Silences are
more silent by an order of magnitude; the soundstage is broad, deep tall;
instrumental timbres have an uncommon truth to them; dynamics soft and loud are
unbelievably convincing.
And the Classic
60 are designed to provide years of trouble-free service. You don't need to
be a technican to use and enjoy them. Quite simply, the
Classic 60 bring world-class audio performance within reach of most music
lovers. Audition one today at your nearest Audio Research dealer.
For effortless
musicality and value second to none, it
has to be the Classis 60.
The Classic 60
Hybrid Stereo Power Amplifier resembles the long-popular D115 in Audio
Research's 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 don't always
describe a power amplifier's 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 60's eight 6550 power output tubes. Additional circuit
improvements as well as the usual rigorous parts selection and manufacturing
Audio Research is noted for also contribute 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, timbers of individual instruments, soundstage
and musical emotion all surge out rom a black velvet of silence.
Simply put, the
Classic60 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 Research's Sp14 or Sp15.
Convenience figures
high on the Classic 60's list of attributes, as well. For example, DC balance
of the output tubes is maintained automatically, while tube biasing
continuously adjust to changes in incoming line voltage. Performance stays
razor-sharp without bother some 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.
