I am using a Krell 2250 w/Thiel 3.5's and a VTL 5.5. The 5.5 is quite good w/excellent bass control. It has remote volume, mute, phase inversion, and HT bypass. I previously had a Krell KSL (I still have it) and I really like the detail, warmth and "creaminess" that the VTL has added. There is a used one at Upscale Audio. Of course, your source will also have some effect on this. Good luck. I think you are really on the right track.
