I would not exactly call it upgradeitis. I was demoing diffrent brands of speakers in my dedicated theater to replace my old ones. I ended up really really liking the qs8's and maybe even the m50's. I have not found fault with them yet. The vp150 maybe another story though. I can hear a slight resonance on some voices and it can be almost painfully bright. I can eq that out if it though. Something tells me the problems may be tamed by two of them side by side. It's now hanging just above my 133" screen slightly off center. I think thats why the sound seems off.
