Yes, everybody keeps hearing the same thing from me about Herron Audion. But I haven't read anybody that disputes anything I've written.
Since you asked for it, Ill share my experience!
I have only auditioned the Herron VTPH-2 at the agents showroom, and never used it in my system. However, I have 2 Herron VTPH-1 , one stock VTPH-1MC Plus, another was updated to the Plus status from the original VTPH-1MC. Yes, I liked it enough that I got 2. For that matter, I also have a VTSP-1A/166.
My following comment is based mainly on my experience with the VTPH-1MC Plus in my own system, but my impression with the VTPH-2 in the agents showroom was similar.
The Herron VTPH-1MC Plus is very neutral, very quiet, and certainly a bargain at its price range. However, for the good or bad, it lacks somewhat the tubes warmth and tonal color. Also, when compared to some more heavily built (and more expensive) phonos, the Herron seem to lack behind a little on mid-bass and bass authority.
Of course, that is based on what I heard in my system and my personal preference, so YMMV. I have no doubt that the Herron is a good phono, but is it the only choice in its price range? I suppose it depends on your preference and matching gears.
I am not trying to talk down on Herron gears, but just want to add a more balanced view.
