I'm no expert when it comes to tube amplifiers but I am running an inexpensive ARC VT-60 with a Modwright linestage (highly recommended) and Paradigm Signature S4 speakers. I was ready to sell the S4's when I tried the ARC amp. My solid state system consists of Mark Levinson No 23.5 and No 27 in a bi-amp configuration.
In a word ... it was incredible. I'm using mostly Signal cable silver resolution IC's and Frank's Shotgun copper speaker cable. I was running a Rotel way back when and I upgraded to Nakamichi PA-7's and finally older Mark Levinson amplifiers. Each time it got better and better ... but the ARC amp was a huge jump. I'm now looking at amps in a similar price range to what you are seeking. I'd like to hear the Audio Research VT-100 MkIII - It can only get better. I am also looking at the McIntosh 275's (possibly a pair) ... I figure that should be enough power to handle a lesser efficient speaker but honestly I hesitate to make a change right now. I like it so much - I dont want to screw it up.
I'm also interested in VTL (mono blocks) but I have yet to hear a set.
Good luck ... I think we are on the right path.
