I need some advice from 950/770 owners. I'm completing my HT and am trying to decide between the Pioneer 49txi and the 950/770 combo. They both have the features I need. The 49tx has some nice to have features that the 950 does not (Auto calibration, video upconvert, THX). Features aside, for me, the real and olny issue is how does it sound. Have any of you 950 owners had a chance to compare with 49tx or 5803? From a purely sound perspective, were you able to tell the difference between the 950 and a flagship reciever? I really appreciate your input!
