I will give a bump to the HK990 recommendation. I used one in my HT when it was 2 channel, and now use it in my bedroom system. It is a fantastic integrated, with a really good DAC, and the room correction is a necessity IMO. I now run it with a pair of Tannoy DB8s, and a Mirage sub. This is a serious amp that will make a big difference in the sound quality of your setup. Highly recommended.
