The
performance specifications of Yamaha's CR-1000 professional-class stereo
receiver are distinguished i two ways; they are superb and, like all Yamaha
stereo specifications, they are conservatively rated and guaranteed. This of
course says a great deal about the kind of quality the audiophile should expect
from this receiver; but it says even more about the company that would build
it. By any standards, the CR-1000 is an important achievement. It is a
combination of an outstanding FM tuner and an extremely low-distortion,
high-power, versatile amplifier, both of which could stand by themselves as
independent hi-fi components. (It does not include an AM tuner because the
discriminating music lover would most likely prefer to be without it.) the unit
features the world's first application of negative feedback to the FM tuner's
multiplex switching circuit, resulting in very low harmonic distortion and
intermodulation distortion. Power is prodigious; RMS continuous output of 70
watts per channel into 8 ohms, both channels driven, at 0,1% THD over 20 Hz to
20 kHz. Because the FM tuner uses an elaborate 5-gang tuning capacitor, as well
as a triple tuning circuit with dual-gated MOS-FET's, the quality of FM
reception is at the highest level presently possible for a tuner of any cost.
Which leads us to another significant facet of the CR-1000. with all its
excellence, you shall discover its price to be surprisingly agreeable. This, by
itself, makes the CR-1000 a most unique stereo proposition.
