Lots of folks on here with Sansui quad amp experience, maybe not that model....A search just shows the occasional person bopping in with a question on one. How did the powering up go?

You might have better luck if you ask specific questions about the receiver. You really don't just want to know who owns one, or do you? Many of us own (and have owned) a lot of Sansui equipment, and we can probably answer your questions. Please be specific … not "is it any good?" ... "what is it worth?" … "how do I work it?". There is plenty of information on the Internet, so you might want to find out what you can to narrow down your questions. I got this from a quick Google search:

The QRX-3500 has been conceived and crafted to lead the new generation of quality Sansui 4-channel stereo receivers.

Its distinctive styling and high performance specifications have already earned it critical acclaim from professionals and the public alike.

The overall design of the QRX-3500 is based around the new Sansui QS regular matrix system with QS vario matrix 4-channel decoder circuitry and the QS 4-channel Synthesizer.

This electronic ensemble works in concert with the 180-watt 4-channel stereo integrated amplifier and high-resolution FM/AM 4-channel stereo tuner sections for total 4-channel versatility in a medium-priced instrument.

A newly-designed Function control lets you select any one of five 4-channel modes (OS Synthesizer, QS regular matrix surround, QS regular matrix hall, and phase matrix) plus a conventional 2-channel position.

The QS Synthesizer creates an authentic 4-channel sound field from any 2-channel stereo source, while the positions for QS regular matrix system with new OS vario matrix circuit for decoding all QS and compatible matrix-encoded 4-channel program sources.

Records encoded with the SQ matrix system are heard in full 4-channel sound with the function control in the Phase Matrix position. In addition, there are two sets of discrete 4-channel inputs, adding up to total 4-channel capabilities in one complete unit.
