Best monoblock tube amp with Vandersteen 5A

It's not a monoblock but try the Rogue audio Zeus. I a/b'd it against a pair of ARC VTM 200's and found the Zeus to better the ARC's in every way. The midrange on the Zeus is killer in triode mode. I use a PSE HL1 preamp and the combination of these components with the model 5's is spectacular.

Holygrail, Regarding your comment on the subwoofer, is there not an improvment in the mids and his as a result of removing low bass out of the main box, and the freeing up of the main amplifier not having to drive the bass? I thought the use of VS subwoofers went beyond just producing deeper bass.

I'm getting incredible sound with the VAC Phi 220 monos.

I'm very happy driving my Vandersteen 5A's with Tenor 75wp monoblock amps. I also have to agree with Zargon- they also sound great with Audio Research gear.

Joule Electra monoblocks at CES made the best sound I've ever heard from andys. Not sure which model, but it might have been the Rite of Passage. Heard some nice vinyl via VPI Scoutmaster, Joule preamp, Elrod cables. One of better rooms at CES, IMHO. Cheers,
