Herron Audio Reference Line Stage

$6,550.00

The Herron Reference line stage has a proprietary one of a kind tube bias servo circuit that optimizes the performance of many different tube configurations that are equivalent to the 6DJ8 type dual triode vacuum tubes.

The Herron Reference is the result of many years of research and fine tuning for pure listening enjoyment.

“My reference line stage for over twenty years. When Keith Herron has a made a significant improvement, I have upgraded. I know of no line stage at this price that delivers the musical characteristics I find most important to my listening enjoyment.”

Herron VTPH-2A Phono Stage with VTSP-360 Vacuum Tube Preamplifier

– By Bob Craig (Chicago Audio Society): “Keith, I listened to the two units over the past two Saturdays. I used the phono stage (VTPH-2A upgrade) first on its own last Saturday, and then added on the 360 last night, after running another pre-amp for a bit. With the phono stage I noticed more three-dimensionality and more upper mids and high end. With the 360, the result was holy (expletive deleted)!! I couldn’t believe it. You have really outdone yourself with the 360. When I find a component that makes me want to hear more, that is special to me. Most pieces of equipment don’t do that. But the 360 did it. Even an old mono Angel from the 50’s sounded great (solo piano) and a DGG from the 70’s sounded like an audiophile recording. I thought I had pretty good sound before, but this is just beyond. If you don’t sell lots of the 360, there is something wrong with the audio world. It sounds the best I have heard here at home. I appreciate your efforts and hope more people discover what you have to offer.”
