The Classe/Audio Research combo seems to go very well together, I first had the D130 running off of a preout from a Rotel RSX 1065 receiver, then found the Classe for $450 used it was in mint condition not a scratch on it. I was going to go for an ARC tube pre, but the Classe does everything I need it to do(has 3 sets of pre outs, 1 balanced, 2 single ended) I have balanced going to the D130, and the 2 single ended going to each sub, works awesome. FYI I picked up the D130 for $650 shipped it is as well mint.
