I am in a bit of a dilemma right now. My plan was to upgrade my Yamaha HTR-5150 receiver with either the RXV 1200 or the Denon 3802. I wanted to upgrade because the 5150 is just too bright for music. But then a funny thing happened. I upgraded my speakers from Paradigm Titans to Energy C5s. Now the Yamaha suddenly is not so bright. In fact, it sounds very nice. The brightness factor was my biggest reason for wanting to upgrade. Yes, it would be nice to have DPLII, or more watts per channel, or a nicer looking receiver. But for $600-800? So my question is, to those who have upgraded from one Yamaha DD/DTS receiver to a "better" receiver, was the improvement in sound quality really obvious? Right now, when I watch the Matrix or Gladiator, etc., on my system, I am blown away at how good it sounds in my 14X12 room. Does it really get any better?
