Herron pre upgrade...


My system has evolved to a point where I am looking for some specific sonic improvements. I am a huge fan and loyal customer of Herron components. They have been the highlight of my audio purchases over the years. Recently, I had my amps upgraded to M1A's and am enjoying them. My pre is the vtsp 1a-166. The rest of my system is comprised of an Arcam CD23T cdp with Dunlavy Cantata's and mid level Morrow cables and PC's.

I am currently researching a "possible" speaker upgrade (current thread running in the speaker forum). But putting that aside, I have read tremendous things about the Herron's VTSP 3A. The improvements I am looking for I can best describe relating to instruments, most notably guitar strings and piano notes. While things sound good, they seem slightly flat to me or to fall off quickly. Overall low to mid volume performance is another trait I would like to improve. Currently, there is quite a step-up in musicality at mid+ volume levels. Often a touch higher than preferred for daily background music.

Being a hobby enthusiast at best, I would be very interested in hearing from others who may be able to help critique the components I have assembled. Any input related to the 1a vs 3a preamp would be great also. Maybe I should be considering the jump up to the 3A before moving up to another speaker.

Thanks for your time.

Not specific to Herron, but upgrading the preamp could result in a very significant improvement in the system. If you have the chance to audition one without risk, I think that would be the way to go. From the tone of your post, and maybe I'm wrong, you sound like you basically like your system, but you're getting a bit bored. It happens. But I still think that few people here really understand the upgrade a preamp can make. Providing you're moving to a better one, of course. Good luck.
I previously owned a Herron VTSP 1a-166 preamp and my experience echoes yours and Tenebaum, I found the preamp to be overly neutral, lacking a bit of air and dimensionality. I ended up selling it and have never looked back. I currently run an older Deja Vu Audio preamp and am very happy. I firmly believe there is no more important piece in a system than your preamp. As Chayro says above the improvement can be quite startling. I can't offer any thoughts on on the VS3a sorry.
The Herron 1A pre was my first Herron Product. It has trumped other similar budgeted pre's even through several amp changes. Recently, I made the step to the matching Herron M1A amps. It was a revelation in detail. So much so, I pulled the Arcam CD23T back out of the closet to replace the Bryston cdp we long ago decided on for its perceived added detail. The Arcam cdp absolutely provided a much more pleasant presentation in our environment which I would certainly consider lively.

Now after some critical listening and paring of components, I am indeed bored and willing to attempt some more refinement. We have a flute, piano, and guitar player in the household. So naturally the music quality is a priority. I have no desire to revisit changing amps at this time, so I have been focused on a more efficient speaker upgrade that would mate well with the Herron M1A's. I do not believe my current Dunlavy Contata'a to be that efficient at 90db 4ohm. But after much reading and not being particularly unhappy with the Cantata's sound, I am thinking the preamp may be a logical next step for some exploring.

Thanks for everyone's time who has commented. I very much enjoy reading the great articulate feedback and experience of the many members.
