thanks for the shout out on the speakers! Home Audio is one of those areas in the store (along with car audio) that I don't venture in to that often, so my knowledge isn't complete for that stuff as it is for tvs, appliances, mp3, computers, etc. and ITA with the suggestion of Denon and those other brands. Those, along with Klipsch, are usually what our hardcore home theater guys suggest.
I'm guessing your store doesn't have a Mag in it? I know that I typically recommend Definitive Technology (amazing sound, but not a home theater in a box setup, you pick out all of their components separately), or Martin Logan, again amazing sound but you pick out all of the speakers separately. I'm pretty good with home audio and car audio, I'm might be able to lend a hand in answering questions on some of those things.
