Thanks again for the responses. I'll probably try this over the holidays - have all the equipment, so not much to loose, except my wife yelling at me for the mess it'll create.
The history: system generated great sound incl bass w/ my Rogers Studio 1As. With the move to the new house, the bass got sucked out in my new listening room. (I need to do some room treatment too). To compensate, I've moved to larger and larger speakers, currently Proac Response 3.5, which are not as efficient as the Rogers. I'm told that more power might improve the bass..thus this current thread.
