Wow, I wish that was my starter system.....but many people are correct, system matching is critical but I don't know your components Only 2 suggestions:
(1) Get some room treatments, others know way more about that than I do. But, a heavy area rug, think curtains, and a few panels from GIK Acoustics worked magic
(2) As some have mentioned, run your amplification directly from the outlet.....through a power conditioner/protector is no bueno. Better yet, run a dedicated line (or two): dedicated line and audiophile outlet (PS Audio, Furutech, etc) and run through that
