Hi Lew,
First, to be sure it’s clear the input stage of the Herron for LOMCs is FET-based, and does not use a 12AX7 or any other tube. I believe you are correct that the MM input stage uses a 12AX7, and I assume that stage is in the signal path for LOMCs as well.
Essentially all I know about its design characteristics, though, is what is stated in the description and the manual that can be seen at the website. Among other features, undoubtedly passive RIAA equalization, absence of any feedback, use of "high quality very low dielectric absorption film type" capacitors in the signal path, "four levels of high voltage regulation," use of "hand-picked components," and internal star-grounding are significant contributors to its performance.
Fundamentally, though, I believe that the most significant contributor to its performance is simply Keith Herron’s combination of technical expertise, musical sensitivity, and dedication to excellence.
Best regards,
