Audio Research Ref 10 vs 40th Anniversary preamp


I was wondering what the difference in the sound between the Ref 10 and the 40th ? Not much wrote about that. I btw have the Ref 6 but never heard the 10 or the 40th.

Run dont walk and listen to the Coincident Line Stage
it will sound more transparent,open and as dynamic as the Ref 10.
Unlike AR, Coincident is made with point to point wiring no circuit boards, no capacitors in the signal path, Direct Heated Triode 101 tubes and seperate 45 lb. power supply.
