Nice setup. My friend had the s3.4s with mc402, driven by cary slp-05 and a marantz sacd player. It was very a musical, dynamic setup that i've always looked forward to hearing. I'm currently toying with the idea of mc402..or pass x250.5 (actually had this amp with my former s3.4s) to go with the s5.4s but I have to sell my Plinius SA102 first (the big dyns need more juice). It's such a DOG market though, i'm practically having to give it away.
Just a few months ago and this amp would have been sold in moments...anyway, awesome setup. I'm sure it sounds wonderful!
