Music hall Ha 25.3

Hello,
Does anyone know this amplifier here?

I thought it could be interesting to drive the Aeon R/T distortion-free, for example.
It is a hybrid amp from the USA and seems to be solidly built.
Also something different than the stuff from China.
Not that I’m unhappy with the Little Dot 1+, but its quality is a bit weak.

I would be interested to know if you can change the tubes, as the predecessor PH 25.2 had fixed tubes, so nothing to do with rolling tubes.
And I would be interested to know how good it is if anyone has it.

The price is not bad and attractive.
What do you think?
It hasn’t been mentioned much in the community.
