Sansui QR-1500

Description

The Sansui QR-1500 4-channel receiver incorporates Sansui's unique synthesizing/decoding matrix (patents pending) that produces a multi-dimensional sound field so enthusiastically received by many audio experts as purely revolutionary.

An instrument that literally heralds the new age of 4-channel stereo sound reproduction, the QR-1500 not only converts ordinary 2-channel stereo discs, tapes and FM broadcasts into immensely richer 4-channel stereo sound, but, working in the capacity of a decoder, restores any 2-channel material encoded from four channels to its original full-fledged 4-channel status.

It also incorporates the four all-silicon amplifiers which enable you to use a 4-channel tape machine to reproduce discrete 4-channel stereo.

Hard to fault this unit. Sounds like a $2000 valve amp, but more power...
Warm, super clean and detailed sound that makes you forget the actual position of your speakers. Dynamic and strong bass, sweet highs. I can only recommend to test this device yourself if you ever have the opportunity.
