Just received my new 80.3 a few days ago. Finally found the time to remove the old DTC 9.8, complete hookups, reprogram Harmony remote slightly, etc.
At first I thought it was a tad too bright, audio-wise. But tonite I sat down and really started throwing some of the best-recorded Blu-Ray DVD's at it that are in my collection. Mostly concert videos.
Picture is wonderful, as expected. But the sound is much more detailed, but not too bright as I had feared. It IS unforgiving of poorly-recorded audio, but can be quite revealing. I think the better Audyssey EQ makes all the difference over the old model. I was using the DTC 9.8 Audyssey in conjunction with the SVS AS-EQ1 sub eq, so I was getting the XT32 sampling for the subwoofers, but not the main system. Now, with the XT32 sampling from top to bottom, (using two SVS PC12-NSD's), the whole system sounds more coherent, and seamlessly integrated as though the system consisted of one giant full-range speaker.
So far I am *really* knocked out.
