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

System:
Rega RP8 with Apheta 2 cart
Rega Aria V2
Khozmo (mostly) passive preamp
STA 9 monoblocks 
ML ESL X speakers

It’s ignorant to clump all class D into the same basket
It could be your passive Kuzma. I had the Hattor passive, and although I loved it, I think there was an Impedance mismatch with my class D amps. Upgrading to the advanced input buffer (~$350) + shipping back to Poland. If you’re handy you might be able to order them an install yourself

Depending on your budget there’s a pair of Merrill Veritas for sale < $5K
and PS Audio M1200s with tube input stage should be available now

I have a Audio Alchemy DPA-1 + PS 5 that I replaced the Hattor with. It made a big improvement. It's for sale on AA and USAudiomart
