I just got my hands on a QRX-9001 after a 30 year wait! I'm running a pair of Tannoy Mercury M20's and B&W 602's. That power and THUD :) I'm listening to all of my music again and I really can pick out sounds I've never heard before.
10 out of 10, thoroughly impressed.

The QRX-9001 gets a 10 if working absolutely perfect. Which is rare nowadays especially in original condition. Mine used to and the powerful quad sound was nothing short of awe! I use a 4 channel 8track player that's serviced and restored, sounds better than compact discs.
When competing against my G-7700, the battle was close. But the 9001 seemed to have more detail and separation. At high volume, the G won, but it's also 40wpc more if more.
Note: both have not been driven past 40 on the volume dial because it's just to f'ing loud.
The 9001 has quad ability no other quad receiver has because of the new chips/ matrix of QS only used in this model. Meanwhile the era of quad went down as the 9001 hit the market and no other brands were producing quadraphonic gear. So Sansui made the supposedly last quad and the best and the most powerful. Granted it's not as flashy looking as a 4400, the 9001 will crush any and all quads in sound performance.
But they have a tendency to have issues once they reach vintage maturity, 30 years later.
Quadraphonic is the real surround sound.
