Do you have a website link?I am in the process of picking up the Jadis line and am going to be curious how Jadis JA 30 Mk II stacks up against the Art Audio Opus 4 KT120 vs. KT120. I have not heard the EL34.
In my opinion, the Art Audio Veloce EL34 mono-blocks are a tremendous value for the quality they deliver, 25w in Triode. Small form make them easy to work into a room. At $10,500 they are not crazy expensive.
