I really liked the Citation 7.1 THX amp and used it to bi-anp my front speakers and it sounded great but did leave a hole for the center channel. I purchased an EAD PM 1000 and love it. More depth and bass as well as more power and channels. Spend the extra $$ to get a PM 1000, the comments on the PM 500 I've read are good but may be underpowered depending on your system.
