Buckeye, It does make sense to start at the receiver. I was thinking if I do the YPAO setup, I might as well upgrade speakers at sametime and only do it once. But then I'd have 2 variables and not clearly know which was the poor performer (speakers or receiver) even though its probably the latter.
Although both Denon & Yammie get raves on this site, I'd have to say it looks like a lean toward Yammie (Zumbo must be smiling

). Now I just need to wait till Fall and hope that the XM feature is included in the 2500. I'll be angry if I buy it now only to have the XM version come out in 5 months and I don't want to go the Polk dedicated XM unit as I've read mixed reviews.
Probably start looking into Paradigm Monitor 7 pricing in case I get real impulsive.
