I am with the groover, go with the ARC all the way and forget the rest. In Bill Johnson we Trust! Use a transistor go to jail. I recomend ARC amp and pre and Vandersteen or Magnagans. Use the vandersteen subwoofer and you can get away with a smaller amp. 10k will buy a hell of a system with this approach. An ARC VT50 with a Vandersteen sub is a great set up and gives you the realism of the low bass.
