Hi there @ghdprentice In my system I didn’t find the Mkii Audions to lack a bit of refinement on the top end but I would say that the Mkiii GaNTubes have opened up the top end quite significantly. Last night I was listening to Talking Heads ‘Little Creatures’ on vinyl - it’s a great recording and the drums/cymbals were the most life-like I’ve heard from my system.
I had a look at the AGD website and the designer (Alberto Guerra) outlines the design improvements he has incorporated into the Mkiii tubes. I don’t understand it all but this gives a bit of insight:
“With the new MKIII, we have extended the frequency response of the power stage, now flat up to 60KHz, and by a combination of layout improvement and the re-engineering of the output filter, we managed to also significantly increase the slew rates performances.”
There are many way less costly options and are too expensive for people not into high end audio (99%?) , but having heard them they sound very good and are likely to retain a niche in teh high end world for the foreseeable future. Plus the modular tube like aesthetic on the top models (despite not actually being a vaccum tibe) will appeal to tube lovers that otherwise might hesitate to leave tube amps behind, and may provide a good path for upgrades moving forward I would expect.
Myself, I grew up in the 60’s and helped customers with tube replacement working in various electronics stores back in the olden days when tube testers were still a common sight even in some drug stores. So I have a nostalgic soft spot for tubes. THese days I am a long time career tech guy and have come to the realization that vacuum tubes are still way cool looking and all glowey and stuff and often sound very good, but practically their time has come and gone. My reference system is 100% tubeless these days (yay!).
But I still have that nostalgic soft spot in my heart for tubes and the AGD design does float my boat by adapting a vacuum tube like aesthetic but putting much better 21st century amp technology in there. The best of both worlds for me but still only for a premium cost....
