Opinions on Graaf Amps

Does anybody have any expereince with Graaf OTL amps? I'm especially interested in the little GM 20 but don't have a chance to listen to it where I live. Has anybody heard it? In my search for a new amp I have listened to the Carys (572s) and found them overall too bloomy. I don't like tube amps that try to sound like solid state (i.e., Audio Research or BAT) but I also don't want the tubes to color the sound too much. I've tried the Atma-Sphere S 30 which sounded terrific in my system, open, airy and very musical, but it just runs too hot. So now I am considering the Graaf or perhaps an Air Tight. Any thoughts would be appreciated.

My system:

Joule Electra LA 100 MK-III
Merlin VSM + BAM
Audiomeca Keops as transport and Audio Logic 2400 DAC
JPS Super + speaker cables, FX interconnects, and Power Cords

Many thanks,

Dr V

Yes I absolutely love the hot blooded and hot running GM200.It is alot more dynamic with more "air is there" and also more body to put Heidi Klumm to shame.However,the Chapter amp put my musical experience on another level.Now to be honest and sincere,this is my subjective opinion.And you can read what a reviewer said(and the one who got me to investigate):

Hy, I have two Graaf GM20 and the 13.5B II preamp. I absolutely agree with all the good reviews posted here. GM20 is a kind of magic.
