Hattor Ultimate Power Amplifiers


I am wondering if anyone has tried Hattor Ultimate Power Amplifiers? I am currently driving Martin Logan ESL X speakers with a pair of Nuprime STA 9s as mono blocks. I am happy mostly with the soundstage and detail I am getting,  but I am experiencing a little harshness at very high volume and I am wondering if next level class d will afford more musicality and punch. Anyone with experience going up the food chain in class D amplifiers have any insight on this? Thanks,  Tom

Khozmo (mostly) passive preamp
STA 9 monoblocks

tomflyn, you have ESLs and I think you are barking up the wrong tree.
ESL lovers generally shy away from class D amps because they have a tendency to sound harsh. I think you would be better served by getting something like the Parasound A21+. For the same money you could get two of them strapped. They are high bias class AB amps. I use ESLs and use the same type of amp. In the near future I will shift back to pure class A which I think is the ultimate for ESLs. The Amps that Sound Labs recommends most for its speakers are the Atma-Sphere MA 2 and the Parasound JC 1+.
