I just bought a new 563a for its music playing abilities (SACD & DVD-A). My setup is a 2.1 no center and no surrounds and I'm running bookshelf fronts. When I hook up the player with the 6 channel outs and tell the player that I don't have a center or surrounds there is no LFE output to the sub. I have even boosted the sub output by 10 db and there is still no sub output. If I tell the 563a that I have a small center the LFE is there but them I'm missing most of the music since I don't actually have a center channel speaker. How should I be hooking this up to listen to hi res music on my 2.1 system?
