I thought I would resurect this thread to tell you about a recent discovery. I listened to an Audio Research Reference 75 recently at a recent small show and was very impressed indeed. I have decided to work an extra year before retiring, so I figure I deserve a present. The Pathos Inpol2 I have been using for several years, has been great, but perhaps lacking a little drive and dynamics.
I took delivery of the ARC a while ago and like Lou's speakers, this is a very special piece of kit. I know Lou favours Modwright and the power amps are excellent with his speakers. I still find, they have a tad too much solid state, grain to them. The ARC has all the drive, micro and macro dynamics, pinpoint imaging and soundstage depth, of the Modwright, but is mich more organic, it sounds like live music, less a recording. I am using it with a clone of the Music Audio Baby reference passive TVC and find the combination excellent.
If you had the chance of of borrowing a 75 from a friendly local dealer, I would encourage you to try. It is plenty powerful enough for Lou's sensitive speakers. I have'nt managed to move the power meters on the ARC at all yet
