DZ,

Got the 2805 and it is most certainly an improvement over the Sony (as is to be expected). The amount of features for tuning specifically for your room is great, especially the auto setup with the microphone. It picked up distances and minute differences in the speakers to set my room up perfectly. The sound is much more crisp and clean in all facets. Good luck with your Sony, hopefully you'll get better results than I did with one.

If not...

2805 is $619 at www.pricesrite.com
