I was actually looking at the T753, the one you mentioned. That's about as high as I can go...well, actually, the price point on the Rotel is as high as I can go, with the T753 coming in under that.
Decisions, decisions.
Aside from that, with either of these models/brands, am I correct in assuming that both would be a step up from the Onkyo TX-SR602, or are their benefits (particularly in 2ch stereo mode) negligible when compared to my Onkyo?
