Chang,
I use the DNA-125 with the AES DJH edition AE-3 pre. Speakers are JM Lab 915.1. Sonic heaven. The DNA-125 drives the 90db sensitive 915.1's without effort. I think the Vandies are a little less efficient but I think the DNA-125 would be an excellent match.
I've been a big fan of solid state amps and tube pre-amps. The best of both worlds.
Good luck.
