Dan, I have a Theta David transport, Krell AV Standard, Krell FBP300, Thiel CS6 set up. I have been really impressed with Synergistic Research Designer's Reference interconnects throughout (I am using active shielding). I agree that you may never get the smoothest, most liquid sound. However, if you want impressive dynamics, speed, and slam, you can't go wrong with the amp. The SR cables added so much depth to the soundstage, I was hooked from day one. Of course, others here have said the same about the incredible soundstaging. Good luck!
