Tube amplifiers that really drive MBL 101E's

I've been listening to a pair of H2O M250 signature monoblocks (solid state, class D) amplifiers for about a week now. I'm very pleased with what I'm hearing and have decided to keep them. I no longer feel the need to get the 9008s but at some point I do look forward to hearing David Berning's OTLs in my system.

Exlibris, please post more on what you are hearing with the H250s and the MBL 101Es! If the H250 can do a really good job with these speakers, it will be something of a revelation...normally the only amps that get recommended are the super-pricey ones, as I'm sure you know.

What other amps have you heard on the 101Es, if any?

Calanctus, the only other amps that I've heard with these speakers are the MBL 9008s. Having said that, I heard them in a completely different system in a completely different room. What I took away from that experience was a sense of: effortlessness, realism, transparency, speed, and incredible macrodynamics (especially below the midrange).
I'm getting all of those qualities in my system with the M250 signatures. Right now I am limited by the size of my room: 18' x 12' x 7'-4" and the fact that it has no acoustic treatments and a bunch of furniture in it. I'll know much more in about 3 months when I move into a dedicated listening room.

My Vac Phi 300 did a very nice job makeing music on the MBL 111e. In my short audition I prefered it to the MBL's biggest badest amp. I liked it better for all the reasons I like tube sound.

I'm currently using a pair of Atma-Sphere MA-2 mkIIIs.
They are best I've heard so far with my 101Es.
