Hi Mantis007. My local dealer is an Audio Research dealer. Prior to the availability of the REF 210, he ran the VTM 200 in his "reference room" quite often. He has run the REF 210s in the "reference room" for the past few years. The problem with me making the comparison for you is that the speakers used are entirely different. Back when the VTM 200 was used as the amp, the speakers were Watt/Puppy 7 and since the REF 210s have been used, it's the Maxx2 or now Maxx3. That said, I think the REF 210s are in a whole other league. The biggest difference that I remember is the space around instruments; MUCH better on the REf 210. VTM 200s are excellent amps. Good bass, excellent mid-range, smooth treble.
