This may sound dumb but I need the correct answer on this. I am looking at a Marantz Slim line to power a small 3.1 set up. The AVR is the NR1506.. Am I able to use the pre out hook up to run my RBH SX-6300R right and left channel and use the AVR to power the center channel? I was sure. I don't think the Marantz AVR with 50watts will be enough to drive the 88db sen RBH to higher volumes..
