I've got the Three panel model X with the servo tube amps, modded and upgraded(lots of Furutech parts)
I also like the sound of a passive pre amp, in my case, the LightSpeed Attenuator.
I have other friends who use tube pre amps and their sound is not as clear and defined as my sound is.
I thought it was the upgrades, but perhaps it's the LSA.
Enjoy your 2+2's.
I've had stacked 57's, a pair of 63 on Arcici stands, Martin logan CLS 11Z(2 pair) and way back the medallion Acoustat3 with a Conrad Johnson MV75-A amp and CJ Premier two pre.
They all have something special about them, but what I have now is the best sound that I can remember with any of my stats.
Of course these are powered by the servo amps, so that takes a lot of the guesswork out of finding the right matching amp.
I don't think using the same amp to audtion the Quads and the Acoustats is going to give you a definitive answer.
One speaker will be handicapped.
Borrow a few different power amps if you want to get the full measure of either speaker.
