FWIW, I am driving a pair of Vandy 2CE's with a Rogue Tempest Magnum, and the sound is excellent. You might consider the 88 Magnum, the M-120 mono's, or the new M-150's. All are excellent amps at their respective price points.
Also, FYI - based on pics from CES, it looks like the Vandy room was using a pair of Audio Research tube mono's to drive the new Quattro's. If the mid's are important to you, I think either of the tube amps you mention would really make you happy.
Best of luck,
Eric
