Audio Research Ref210 vs Ref300 vs VTM200


To Audio Research owners.

Is the Ref 210 that much better than the Ref 300 MKII and/or the VTM200.
I have a pair of Classic 120's upgraded by GNSC including balanced inputs and i am looking for little more power in the bass area. Those 120's have become superb sounding amps with the GNSC mods. Thoughts and comments welcomed. Looking for used unit. Rest of system:
Verity Audio Parsifal Encore
REF 2 MKI with GNSC mods and Amperex PQ white label 7308
REF Phono with """""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Sota Cosmos series IV.

Not to really mess up your thought process, but have you considered a Ref5? I got one recently, and it is really incredible! I had a Ref3/Ref110 combination for a couple of years, and switched over to Shindo Masseto/Montille which was a step up, imo. But when I heard the Ref 5, I had to have it. Sold the Masseto, and used the 5 with the Montille. Now, I picked up an VT100mk3, and it sounds spectacular with the Ref5. My point? The Ref 5 is such a huge step up that you may not have really heard your amp's limits. This is my second 100mk3, and I really had no idea how great they were with the previous preamps, a Ref2mk2 and a Ref3. With a better preamp there may be more life in those 120's yet.
Granted the VT100 IS one of my personal favorite amps - but pair with a $12000 preamp to sound its best? Maybe the VT is better with a hybrid pre that leans towards solid state sound, rather than a pure tube beast like the LS5 - maybe that is why you like it better.
I switched out an LS16MkI for a Ref3 paired w/ a VT200MkI and the difference was profound in terms of detail, imagining, and soundstage depth. I believe the early VT series of amplifiers are all tube.
I too owned a VT200 (mk1)and it was probably the finest amp I have owned. I sold it only because of two repairs requiring freight shipping back to ARC, very expensive. I must add that these were due to buying tubes from a well known tube seller, NOT from ARC. Saved some money, and it cost me big time... I won't do that again. Loved that VT200 though.
I also had to send it to ARC for a retube but it has been flawless since. I have thought about giving them a call to see if they would be willing to retube my VT200 with KT 120's and maybe even update the power supply to handle the KT 120. At 13K for a Ref 150 I'd like to keep the VT200!
