Interesting. I never noticed any "electronic" artifacts in listening to the Ref3 (or any ARC tubed gear for that matter). I am not sure what you mean by "organic".
OTH, I might be interested in the bass and mid-base especially where I think there may be at times some unwarranted "warmth" in the Ref3. The ref 2 by comparison has what I would call some bloat in mid upper base. I never cared much for the Ref2 Mk1, the Ref was a major improvement.
