I'd shy away from purchasing a receiver from Best Buy. My past experiences with warranty service from them has been a nightmare, and you'll probably find a lot of horror stories from others. JMOHO, but I'd try a little more "upscale" store. If there's an Ultimate Electronics in your area, they're a safe bet. At least in my area, those guys will bend over backwards to make sure you're happy, and their warranty service is outstanding.
I guess if your wife likes the DSPs, maybe the Yammie would be the way to go. I use a Denon for HT and it has plenty of DSPs to suit me, but again I don't really use 'em. BTW, I also have a DVD-2200 and I really love it. I think you'll be pleased with its performance for MC music from SACD & DVD-A.
