Encouraging report. What are your room dimensions? Are you using a subwoofer?

My room is reasonably large and not evenly shaped. The largest part of the room is 20' wide x 30' long. I sit about 9' from the speakers. 

I do use a sub, it's a Hsu Research VTF-3--which has a 12" woofer.

I think what makes this work is that my DAC has a 2 volt output. 

Thanks. That's a pretty big space, roughly similar to mine. I found my Moth S2A3 to sound wonderful at low volume--the best of any of my amps--but it started to soften on the bottom and strain on top before I felt the room pressurize. Didn't clip, exactly, just lost a little composure and suppleness.

Is your Triode Labs the 2A3 EVO integrated? If so, perhaps the Hashimoto trannies make the difference. Looks top shelf throughout.

I must say, your report is pushing me to put my 2A3 back in for another session!

My 2A3 is an early EVO integrated model, which has James and Triode Lab P10 transformers. I have a photo in my virtual system here on Agon.

I’m also running 12AU7 in place of the 12AX7. They sound much better, even though the gain is considerably lower.

Also: I can take care of the Moth 2A3 if you're not using it ;).

Oh, it's always in use in one of my other systems, continually since 1999! :) Like yours, it is absolute dead quiet, too, even with headphones. Great little amp.
