Help with amp choice, three on short list.

I've narrowed my amp choice down to the following three. The VTL TT25s, ARC Classic 60, or Music Reference RM-9.
All are close in cost on used market. Using Cabasse 96db speakers with ARC LS2B linestage and EAR 834p phono. Listen to jazz/classical/opera. Small room 12x25, vinyl and cd for source. Any experience comparing these? Or any other I should look at? Pros/Cons of each?
Any help appreciated
