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

I have had the GM20 for about 3 years now, and it has been back for repairs about 4 times. Each time the problem is the same, i.e. one chanel starts to hum and one of the capacitors needs to be changed.

My speakers are JM Lab Utopias.

Has anyone had this experience, and if so, is there a fix? Or do I just have a crappy unit?

None of the above letters seems to indicate any problems, so I'm wondering if there is something wrong with my set that needs to be fixed, apart from changing capacitors every year.

I'm very happy with the sound, but I also dont want to have to struggle with repairs every few months.

ANY help would be appreciated.
