Currently I have b&w dm303 box shelf speakers for fronts, a denon AVR 1601 receiver, a klipsh sub, and a pair of old sony apm x270 speakers (I don't know what to do with the sonys). In the long run I intend to get B&W all around... so I'm missing the center ch and the rear speakers. From what I've read i could just get a matching pair of dm303's for the rears as well. When I got those I think I paid $300. I'm assuming the price today isn't much different. Based on price range I'm probably going to get the same for rears. Or would any of you advise otherwise? I've always had the impression rear speakers were typically never as good as your mains are supposed to be. I basically don't want to over pay for a component. Can someone elaborate? lastly... my sub settings. There's a low pass setting, an in-phase setting, and also 2 different speaker connection types (line in vs speaker in). Can anyone explain or point me to information on these options?
