I have my 990 set up and calibrated.

Seems nice so far. I am using Springsteen's Devil's & Dust DVD 5.1 mix to compare with my previous setup. Sounds nice and more extended on top than my previous setup (pre/pre out section of a yahama 5560 reciever), however the more extended, the more I tend to hear
compression artifacts from Dolby Digital, etc.

Also seems like I am hearing more small details of instruments than before as well.

I am impressed with the auto setup via mic, though I do wish each channel could be raised in .5 db increments- 1 db to me seems like too large a jump.

It does support 96Khz DVD's (I have a few of those precursers to DVD-A and SACD) though a few times I got dropouts. Those disks didn't benefit from upsampling though 44.1 CD sound a bit smooother through the upsampling.

Overall I;m quite happy with the build quality, sound and features for this price.
