Why does it sound so good to me?

I posted a few days ago that I finished recapping a Quad 303 amp and installing the Net Audio PS and rectifier boards. I used the original specified values and adjusted the bias. My system has an odd ball rare Pioneer C-Z1 preamp to the 303 and Altec Model 19's.

My question for those who know more than I do is why does the 303 match so well to the 19's? To my ears even with new caps the clarity and control is surprising. This little amp has very good imaging, amazing clarity and a sense of realism that's almost scary. The bass is well controlled and the highs are clear and defined. Does the impedance load offered by the Quad work better with some speakers? I'm stunned but happy and it's hard to get away from the system at the moment.

Previous amps I've used with these 19's include: Pass Aleph 30, McIntosh MC75's, Bottlehead 300B/2A3 Paramounts, Heathkit UA-2's and Pioneer M-Z1's.
