I have put my receiver away since I never use the tuner. I run a Pioneer CQ-800A preamp into my Marantz amp.
Any stereo source can deliver a synthesized surround effect, regardless of source. The quality of the effect will be dependent on the particular recording. Some will be better than others. Both the 7001 and 9001 can do a very good job of synthesizing surround from stereo.OK that is what I would expect with a stereo source in the discrete mode as there is no rear channel information to reproduce.
I'm looking at getting a 7001 or a 9001.
What I would to confirm is whether one can get a synthesised 4 channel effect with a stereo (non turntable) source. Looking at the online manual for the 9001 there is a QS synthesiser mode that would appear to do this. Is this correct? And if so, can the 7001 also do this?
Technics SA-8500X but two pre-amp channels are fried. The just blew out this summer. Know where I can get replacements?Enough Blu-Ray, HD-DVD, SACD, DVD-A. How about some quad guys posting what they have for their receivers! Probably the pride and joy and center piece of a quad system, let's list what we have, and pictures are cool too. Especially if it's a rare unit.
Any all of you guys who never post because you have no reason to, comon, let us know what you're using. Amps and Receivers from the "quad era"!
I'll start:
I have a Sansui QRX-999, which is a European version of the QRX-9001 which I bought in Italy when I was in the Navy back in 1977. I carried that sucker up the fantail stairway on the aircraft carrier I was assigned to and it was heavy and awkward and I amost fell off the damn thing. But it was worth it! Still working today.

I use a fully restored Sansui QRX 7001 for QS and RM, a fully restored Lafayette LR 5000 for stereo, SQ, and CD4 (via a JVC 4DD5). I have a spare fully restored LR 5000 and 3 spare, still in the box, JVC 4DD5s.I have put my receiver away since I never use the tuner. I run a Pioneer CQ-800A preamp into my Marantz amp.
Hi all! Here's my set up. I've got an excellent Sansui QRX9001receiver with a Rockville RPA12 amplifier and Victrola Pro Series turntable with a AT Shibata stylus. Right now I've got two Rockville RSG12 speakers and four decent speakers up top. I plan on getting two more RSG12's and stands for all four.
Now there's a man that's fully prepared.I have a spare fully restored LR 5000 and 3 spare, still in the box, JVC 4DD5s.

I too have the LR5000 and currently playing the new Rhino Quadio recordings stereo tracks through the RM to compare to the Blu-ray quad. It's sounds pretty close with Billion Dollar Babies Hello Hooray. I also have a Lafayette LR-64 with the composer a b circuits that on this forum is said to outperform Sansuis own QS! Well, I have an opportunity to pick up a QRX-6001 on the local marketplace. Looking to compare the RM in the Lafayette to the QS on your 7001, how do they compare? Is it noticable or just barely any difference? Wondering if it's worth the time and effort to essentially switch out a LR-5000 for a QRX-6001.I use a fully restored Sansui QRX 7001 for QS and RM, a fully restored Lafayette LR 5000 for stereo, SQ, and CD4 (via a JVC 4DD5).

Any chance you could get that manual for us? For the last several years going to that website. This is what I get when trying to register:The service manual can be found here.

As for replacements, not sure what you need but check eBay for pieces from parted out units. I would look first into repairing the blown board. The CD-4 Demodulator/phono preamp uses the QSI-5022 which would be very hard to find.
Other than that I would suggest just using it as a Power Amplifier.
I don't think that I should post it here but PM me and I'll send it to you.Any chance you could get that manual for us? For the last several years going to that website. This is what I get when trying to register:

It's my understanding the Lafayette has the better SQ (full Logic) where the Sansui has QS Vario Matrix, better QS. I know my Sansui 9001 has spectacular fake quad in the synthesizer mode, although the blend resistors were removed by the QRX Restore. Separation is quite good.I too have the LR5000 and currently playing the new Rhino Quadio recordings stereo tracks through the RM to compare to the Blu-ray quad.

I'll add to this. I also have two LR-3000s that I rescued and need a little work. And another rescued Technics SA-8500x with bad amps but the CD4 circuitry works and also has a couple Matrix selections 1 RM and 2 whatever that might be.
