Nestor and AVRat, thanks for your responses. Based on what you guys have told me, I have erroneously been seeing a 7.2 channel AVR as my upgrade solution and really should be looking at 9.2 AVRs.
Just trying to avoid "buyer's remorse".
To answer your questions about my external amp: it's actually a Kenwood KA-995 receiver that I bought for $100 on the clearance shelf at the local mom-and-pop audio-video store where I bought all my gear 11 yrs ago. We just use it as an amp for our current zone 2, not as a receiver.
I am just ready to decrease the number of components in my system, and have been looking for the right AVR to do it all.
AV, that Onkyo 1008 you linked is very attractively priced ($900) compared to the new Denon 4311CI, which can be had for a little less than $1,600 on Amazon.
So what, in your opinion(s), would be the difference (trade-offs) between these 2 units?
Thanks.
