Joeinid - In your opinion with the AR Ref 6, is the preamp super highly
resolving, and thus makes imperfect recordings sound just that way,
imperfect? Or is it distorting the signal somehow, resulting in the
forward soundstage and punchy on-steroids feel?
The Ref 6 is NOT distorting the signal. It just doesn't let a bad recording sound good. It lets it all through, good or bad.
I have not heard the ARC Ref 5SE recently, but it's more forgiving and probably not as resolving compared to the Ref 6 (check the thread in the amp and preamp section).
I am personally thinking about the Ref 10 or KX-R Twenty to go with my MX-R Twenty amps.
