Thanks Mike (@mglik)… I did not realize that the ADGs you brought over were MK2. It is great you have had time with your ARC REF 80 as well as hearing my REF 160s.
I look forward to hearing your Dartzeel integrated when you receive it.
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.
