Instead of racking our brains to find rating systems that would yield the
highest specs for Sony components, we rack our consciences.
Take our STR-7065 receiver, for example. We rate it at 60 watts per channel-but under the most rigorous and meaningful conditions: continuous power at all frequencies from 20, to 20,000 Hz., both channels driven into 8 ohms.
Which is why High Fidelity Magazine says: "The Sony.. . is comparable in its output capabilities to many amplifier sections regularly advertised at, say, 75 watts per channel or more" That power rating is taken at a meaningful low distortion figure, too: less than 0.2% harmonic or IM distortion.
High Fidelity comments: "Not only does the amplifier stay below its ratings to the frequency extremes (which the amplifier sections in many receivers do not quite do), but intermodulation stays under this figure to beyond 95 watts at 8 ohms, and beyond 125 watts at 4 ohms.
High power, free of distortion are two of the most important requisites of a high quality music system. The STR-7065 excels in both.
Describing the tuner section, High Fidelity said: "... Both on paper and in the listening room, FM performance of the receiver is excellent." Some of the circuit features that make it so are newly developed Sony FET's in the mixer and RF stages (for 2 µV IHF sensitivity with 90 dB spurious response rejection on strong local signals), and special Sony IC's which give it a 1.0 dB capture ratio and 70 dB selectivity (the easier to pluck stations from a crowded dial). Such power and performance doesn't come cheaply. Yet, when you consider that the specifications you get are better than the specifications you are paying for, the STR-7065 is a remarkable value at $529.50.
And the same value is offered by other Sony receivers starting at $229.50. Hear them at your Sony dealer and see which one rates best with you
