I have the same amp and speaker setup as you (check out my system), and chose to use AudioQuest GR-8 cables (mostly because I needed cables for the long runs to the rear speakers, and wanted to use the same cable throughout my system). There are better cables out there, but for the money, the GR-8 cables are hard to beat.
One thing I've come to realize lately is that power (electrical) and speaker placement greatly affect the sound of my system. Moving my speakers 6-inches back towards the wall and running my RMB-1095 through a Furman power conditioner made a significant difference.
