Sansui 661


When Sansui announced the price of the revolutionary 661 FM/AM stereo receiver, many high-fidelity experts were greatly surprised. The name Sansui has long meant innovation and excellence in sophisticated audio electronics. But it has also meant, usually, that any high-fidelity equipment bearing the Sansui name also carried an expensive price tag.

Thanks to a startling innovation called CBM (Circuit Board Module) developed specifically by Sansui for its finest professional studio equipment, you can forget about price and concentrate on the outstanding Sansui quality and performance of the all-new 661.

This is a budget-priced stereo receiver that delivers expensive tonal quality and performance. Its power amplifier is of a very advanced all-stage direct-coupled OCL design providing RMS continuous power of 27 fully usable watts per channel (total music power 110 watts) with a surprisingly wide power bandwidth of 15 to 40,000Hz with very low overall distortion

It's MOS FET equipped tuner and highly versatile preamplifier and control sections with two stereo tape record/monitor circuits. stereo AUX inputs and much more would normally mean a far higher price tag .

This receiver is simply amazing! If you find one don't let it slip away. This one is better than my other amps; AM69 and newly acquired yamaha A-S500! 661 is my daily driver.
