Allnic OTL/OCL Phono vs Allnic DHT

I’ve owned both the Allnic DHT phono stage and now the newer OTL/OCL phono, and to my ears, the OTL is simply on another level.

The DHT was impressive—open, natural, and full of that classic tube warmth. But the OTL not only brings greater transparency, speed, and clarity—it somehow retains the same warmth and richness of the DHT, but does it better. It feels more refined, more coherent, and more emotionally engaging without sacrificing any of that organic beauty.

I’m curious—has anyone else here made the comparison? Did you find the OTL to be a clear step forward, or did you prefer the DHT’s character?

Would love to hear your impressions.

Here are some additional resources that may be useful-

From the Allnic H-10,000 OTL/OCL manual:

“Some circuit experts might be concerned about DC potential in the music signal in an OTL/OCL design.  However, the chance of this problem occurring can be essentially and reliably 100% mitigated. To do this, Allnic uses a “floating power supply circuit”, a design that deals with the issue by not creating any DC potential in the first place, or such a small potential that it is harmless.”

My personal experience with these units:  the H-10,000 requires less user attention for tube maintenance, more stable circuit and more robust to different environments.
