Tube amplifiers that really drive MBL 101E's

Hi Allan,
Congratulations on the new amps!
Do you know if vetterone has tried the big Atmas or the big Joules with his 111s?

Husk01,
I had assumed that I would eventually have to get the 9008s but I'm in the market for something much less expensive right now. Thanks for the feedback on the Rowlands.
Yes, it would be great to hear the CATs and the 9008s in the
same system.

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.

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.

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

My understanding is that the MBL 101E presents a pretty flat 4 ohm impedance curve. It dips just below 4 ohms in the midrange and then rises in the lowest frequencies (good for OTLs).
There aren't any big impedance swings on the graphs that I've seen.
The Atma-Spheres are incredibly easy to use and they are bullet-proof. Heat can, however, be a concern.
