Actually, when I called Gary Lemay at Quest, he thought too much of the expensive Perfsorber was spec'd and felt I could get away with less but just went with Erskine Group plan as is................I'll just leave it at that.
When Roger Dressler came over he detected two major issues which one has not been addressed yet and will soon be tackled.
First issue earlier noted in thread was 300 Hz problem from front and immediately I knew what the problem was. In haste getting room ready for tour, I didn't line facade screen wall ceiling with poly sandwiched between layers of Linacoustic RC. Since then, have fixed issue but still exists slightly........most likely 1st reflection issue from mains is my best guess.
Second issue noticed was infamous 60 Hz buzz coming from my 6 surrounds which is related to Graffikeye. Lights on, buzz.......lights off, no buzz. When I change out to Krell amp which has balanced connects, no issue. ATI 1807 which has RCA connects is issue. I'll be addressing this issue when I have electrician the whole day and find origin of loop problem along with troubleshooting dimmer issue with noise.
I thought about contacting Nyal........may still.........but if I was told to completely change my treatment plan once implemented......I wont be a happy camper. What I don't know can't hurt me..................besides, I have alternatives to problem solve.
Room sounds great to my ears........and there's always room to improve. Jeff Meyer will be coming in June of next year.......hopefully, I'll have new processor, eq, and speakers ready.
