Power Amp for Hyperion 938

Hyperion tube amps not available locally for auditioning.
I am considering Antique Sound Lab 1009, new Supratek Malbec (but price not released). Anyone has good experience (sound, reliability) with Chinese made amps such as Opera?

Hyperion users, what are you using?

Thanks all for the response. Because I have the Supratek Chardonnay preamp, I think I will try out the new Supratek Malbec 50W amp using KT-88. I hope these are heavenly combo.

I have no problems whatsoever. Surprisingly, the bass is not bloomy at all. Maybe because I am sitting 40% along the long wall. In my previous place, I was sitting to the back wall and the bass was very bloomy. In fact, after over 1.5 months run-in, the bass on the speakers is beginning to sound more punchy. When I first received the speakers, I complained to the dealer that bass was almost missing. My current amp is a cheapo-sort of amp which I bought over 10 years ago; it is the weakest link in the system.

Agree with Ndeslions that cables are also important. I have the AU24 and they are wonderful.
