I have an SP6 preamp and a D75 amp. That combination will work and sound excellent with Magneplanars. IMO it will have more of the tube "goodness" than later Audio Research gear.
Need to learn about Audio Research
Still exploring amps and preamps to go with my Magnepan 3.7i.
I've always heard about Audio Research being a great match, but I'm not familiar with the brand at all.
I'll need to shop the used market since the new gear is way out of my price range.
I am looking for a high power (100wpc +) amp and a preamp that has remote control. I'd like the preamp to be tube, and the amp could be either solid state or tube.
I don't know at what point in the model lineup remote control was added, but it appears most of the older gear did not have a remote.
Any AR experts here?
