I've got good center channels in both my systems at home. It definitely makes a difference. I also have a center channel with the Monitor 7's I just bought. The guy gave me the center he was using, along with what he was using for surrounds. However the center is a small Polk that I suspect sucks for a center, along with what I think are actually a OK set of deck speakers. No idea if those would suffice for surrounds or not. I had figured I would use them for deck speakers. But since I'll be getting the Denon AVR, maybe I should try them as surrounds and see what they can do. Or maybe wireless so I don't have to run cables and drill holes. Any suggestions there?
I do have a Blu-Ray player I'll plug into the Denon via HDMI. It will be interesting to listen to the difference in sound vs Blueooth. If I sell the Emotiva amp, I do believe a sub will be in my future. Maybe the BIC Acoustech. It's supposed to be very good for the money.
I assumed the two sub outputs were intended for two different systems. A Zone 1 and Zone 2 sub. But I guess plenty of people run 2 subs. I've always been happy with just one.
Before I bought the Polks, I found a pair of Wharfdale's at a great price, but by the time I got down to measure to see if they would fit the space, they were sold. Hate I missed those, but they were very close on the fit anyway.
