Hi, im new here and would really like some advice. Im looking to purchase an AVR for my livingroom tv set up. I have a pair of Def Tech BP9060's with the A90 toppers for the Atmos affect. I also have the CS-9060 center speaker and one SR9040 bipolar surround speaker. I need to upgrade my current 2 channel Denon to a new AVR that can power all of these with no problem. I've been looking into Marantz and Denon but im not too familiar with the inner components of these receivers, at least not as familiar as many of you are. What would you guys suggest? Thanks
