When I first bought Audio Research Ref 75Se last year and listen,I did not found it is such a good amplifier compared with Audio Research Old one VT100 MK iii.
The sound is different style from VT100 MK iii. When I listen and listen everyday, I realize 75SE is a big step up from VT100 MK iii, although I still love VT100 MK III.
My understanding for the amplifier right now is that if the amplifier do the emotional narrative or not.
REF 75SE in my opinion might be the top 10 best amplifier in the price under $10000. Now there is REF 80s and the price is almost 50% higher.
Have no experience on Rogue Audio.
