First-off, thanks to everyone for all your helpful posts. I wouldn't have been confident enough to accumulate the equipment below w/o the guidance I received from threads like these and others at AVS.
I recently upgraded my VSX-53TX to the VSX-84TSi and, thanks to this thread, with virtually no buyer's remorse. I wanted iLink and HDMI switching. The OTB sound quality is excellent. However, during my brief time with 84, I've noticed two issues.
Not sure if this was discussed, but the first issue I ran into involves MCACC. During the SW check, setup throws a "volume too loud, retry" exception. My sub is connected using the XOver Bypass input on the OM-200 and it was the same connection used with the 53. I worked-out the issue by reducing the main volume on the receiver until the exception was resolved. The rest of the MCACC setup continued at a much lower volume without further exceptions. The results were a much lower volume with MCACC "on" compared to MCACC "off" and its sounds like the mid-frequencies took a sharp dip.
Ironically, I like the sound with MCACC "on" despite having to jack-up the volume. However, I'm concerned that lowering the volume during the rest of the MCACC setup may have done more harm than good.
The second issue I noticed involves the Faroudja DCDi scaler. Specifically, the Cable output on the Sony GWIII. My Scientific Atlanta 3250 Cable box is connected to the 84 using component cables and the 84 connects to the GWIII using DVI. When 1080i is selected on the 84, the image becomes darker with considerable edge enhancement. All other settings produce the same picture I would get if the cable box was connected directly to the GWIII.
Is there a way to make adjustments to DCDi? I've run through the manual and scanned through the setup menus for DCDi adjustments but have yet to see them. My current settings on the GWIII were done using a DVE configuration DVD. I'm debating running DVE again with 1080i selected on the 84. But I'm not sure if I'm going to see any appreciable difference. Personally, I like the way the GWIII scaler looks.
