I plan on buying Def Tech speakers: Pro 1000 fronts, Pro 800 surrounds, Pro 2000 CC, and a Pro 1000 sub. Because of space limitations on my plasma stand I can only fit a Panny XR-57 receiver. I already have a Panny s52 dvd player that I plan on stacking on top of it which will fit perfectly. Since I have a Panny 50" plasma I thought the XR-57 would be a logical choice. My question is: how will the the Panny XR-57 match up with the Def Tech system I plan to buy. Any thoughts or suggestions?
