First impression: Herron VTPH-2A phono preamp


I got my VTPH-2A this morning and it's up and running. After about five hours of spinning vinyl, I'm pretty sure I've wet myself, MULTIPLE TIMES! I've primarily played vinyl that I've had for decades, music that I thought I was intimately familiar with. I was wrong. There's nuance I never knew existed. Everything about the VTPH-2A is "right". The bass is tight, vocals superb, instruments have places, etc.  All that I've listened to sounds new and fresh and the most masterfully recorded vinyl sounds live. What I've read about on this forum concerning the VTPH-2A (pretty much all stellar) is true. I've had five different phono preamps and nothing can compete with this, NOTHING. It's a bad ass and definitely a keeper.

Just heard from rob67 Al with the Lyra, Herron, Gryphon Antillion, and Wilsons, very impressed with his sound, and looks like he has plenty of gain. I asked him post up here to say where the volume controls are set as I don't know either, he bought the dual mono Lightspeed.

George,
Thanks for the feedback that I requested. I too did a little bit of experimentation. Hooked up my Goldpoint SA1 to the VTPH-2A then directly into the back of my Bryston 4B3. Kicked up the gain on my amp to 29dB and nothing (just kidding). Actually, I have more than a sufficient amount of volume control. The only difference that MAY have occurred going this route as opposed to running through my Parasound JC 2 BP is a little better channel balance.

Al rob67 just let me know that the Lightspeed's logarithmic volume controls are at 12 o'clock for normal loud listening levels on his system.
And as you know 12 o;clock is not even half volume yet, it's 2pm on the Lightspeed. As you can see absolutely no need for any more active preamp gain and the noise it brings.

He also said the Lightspeed wins out over his Audio Research REF-5se and older Pass X1. He's now getting a battery for the Lightspeed and will hopefully do an update here on that.

Gain structure he has.
Lyra Etna SL 0.25mV > Herron 64db > Lightspeed 0db > Gryphon Antillion 30db > Wilson Sasha 90db

The amp's input sensitivity of 0.975v sure helps.

Another bit of information that would be good to know is what kind of music Rob67 used in this evaluation.  Volume levels tend to be set based on the average volume of the music, rather than on the volume of brief dynamic peaks.  My understanding is that the majority of pop and rock recordings are dynamically compressed such that peaks require less than 10x as much power as the average level of the recording (corresponding to a 10 db peak-to-average ratio).  While many well engineered classical symphonic recordings may require 1000x as much power for brief dynamic peaks as for the average level (corresponding to a 30 db peak-to-average ratio), which will usually result in the listener setting the volume control much higher than for a highly compressed recording.

In any event, what is undeniable is that 64 db of gain will boost 0.25 mV to 0.396 Volts.  Although as I mentioned earlier the dynamic peaks of some recordings may result in a cartridge output significantly greater than under the standard test conditions upon which the cartridge's output rating is based.
