Anyone hear the Class D Audio Mini GaN 5 amp yet?

I have the Audion now for two weeks,
They are driving DC10/Viking Berlin’s (MK II).
Very impressed and will definitely keep them.
I had listened to them at Ocean Way Audio in LA and was simply stunned of what the combination of an ultra low noise floor (-130 dB), very low distortion and a SET like signature of harmonics (albeit at very low levels) can do. These amps are a discrete innovation. Specifically, never have I heard mass strings and large choirs so resolved, detailed and natural.
Also the detail and texture at very low volume are simply stunning.
Definitely try them out!

I wouldn’t put it that way. I understand the specific design objective was to create a GaN amp which delivers SET-like harmonics (without paying the price of high noise floor and limited dynamics). In my view this has been completely achieved.
The design of the “chip in a tube” amp board may be a matter of taste. But the workmanship and appearance of the unit are quite beautiful.

Apologies - just realize your question focused on a different amp. Product names seem pretty close.
Still, The Audion, a mini amp :-), is worth a listening.
