I have a Herron, i don’t agree with the above “ we “ opinion. Any of the 3 phono preamps you are considering can best in certain areas the excellent all around performance and neutrality of the ( unfortunately ) out of production Herron. The Aesthetix has no FET front end and is a tube rollers delight. Jim White also offers an extensive upgrade path without throwing away the chassis, etc…
This passion and hobby, especially the analog front end is full of nuance…
Enjoy the music.
