Audion U.K. Power Amps - feedback and experience with their amplifiers?

I’ve had an Audion Sterling KT120 now for awhile and it’s beautiful.

Thank you! Sorry for the late response. Work project kept me away. 
I am a big live jazz fan: Bill Evans, Jim Hall, Miles, but I also listen to classic rock and orchestral music as well. 
The amp really brought a more open and forward live presence to my listening experience. Very detailed, but somewhat relaxed feel, yet still very quick though even with Jimi Hendrix. No fatigue. I have heard quite a few systems and set ups and I am still in awe of the sound every time I listen to a recording (mostly vinyl) Hope this helps a bit.
Here is a list of my setup:

Cheers!
