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

@jkeitel  Thank you for your post!!!

Can you share more about how your Sterling KT120s affect sound quality and performance? Also, your system for reference purposes.

Welcome to the Forum!

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: 

GXT4-1500RT120 In Line Double DC Conversion Battery Back Up

Furman 15i Power Conditioner

Rega Planar 8 + Ania Cartridge

Rega Aria Phono Stage

Apple Mac Mini 2TB with Roon + Tidal Hi-Fi

Audiolab 6000 CDT

Cambridge Audio DAC Magic Plus + iFi USB Filter

Woo Audio WA-6 SET(2nd Gen) Westinghouse 6DE7 pair + Takatsuki 275B rectifier 

Sennheiser HD650 Headphones + upgraded Cardas Cable

Audion KT120 SE - Tung Sol KT120 pair + Russian 6N23P pair

JBL 4530 Custom 3-way (JBL 15” Woofer, 6” Mid and Horn Loaded Tweeter) Cabinets

Custom RCA Inter-connections and internal speaker wiring is solid copper silver wire - RCA connectors are KLE copper harmony

Cheers!

Reach out to @213cobra who has loads of experience with them and FRD speakers

@jkeitel  Thanks so much for sharing your system, listening preferences, and impressions of your Audion KT120 SE. 

It's great to hear you are loving your system. : )

@keithr  Thanks. I read 213cobra's posts across a number of threads when I was researching Audion back in June and then again a few days ago.

I also spoke with True Audiophile recently regarding both the Golden Dreams (300B) and the Black Shadows (845).

Audion remains on my list as I work through finalizing on an amp.
