To go back to the original question, I must say I do like the ARC Ref 5SE, but not the price. I believe ARC do better Power than Pre Amps, just my view. The Ref 75SE I use, is remarkably good.
Some excellent suggestions re alternative Pre Amps, one I haven't seen is the Modwright 36.5, which I use with the Ref 75 now. I think it is clearly better than the ARC Ref 3 and the 2 box version of the 36.5 is definitely better than the single chassis 36.5 I have. I haven't heard them side by side, but I think the 2 box Modwright will be better than the 5SE and a good bit cheaper, plus the company is great to deal with.
