Mobe,
Nice speakers! I use Mac 501's with 3.6's with excellent results. I would strongly recommend you upgrade your cables from 330 shotgun to oracle or 350 evo shotgun. The difference is not subtle, I have used many mits in the past including 330 shotgun, now I use 350 reference and 350 shotgun evo. More of everything in spades. Some cable companies have a best bang for the buck in the middle to top/middle of the line but from my experience the higher up the chain with MIT the difference is huge.
