Reading the manuals for the ADA Mach IV and the QSC-322ua, and reviewing how you say you have your system set up, George is right. By routing all of the analog outputs of your ADA through the QSC, which does both analog-to-digital and digital-to-analog conversion at 48kHz, you have crippled the sound quality of your surround sound processor. You're also having both the ADA and the QSC do bass management. You're not getting what you paid for from the ADA. And it has nothing to do with whether the ADA or Meridian is better. You'd be better served by a room correction system that does A/D and D/A at at least 96/24. I think the ADA TEQ units may fit the bill, but I'm just going on memory from my discussions with ADA at CEDIA.

Dennis, what's your take?
