I own the Pioneer 49TX and B&W CDM 1SE speakers (mains/center will be upgraded soon). I have no complaints. But I do wonder. So, those of you who are using flagships with external amps, what are your thoughts? Which amps are you using and why? Please don't chime in with the "should have gone with separates" or " why a flagship as a pre pro?" argument since it is to late, I already own the 49TX.
