Agree on all the comments about the spectacular sonics of the VTSP3a (Disclosure: I sell Herron gear, Departure Audio). What I think doesn't get recognized enough with this piece is how intelligently it's designed and how good the ergonomics are. There are really useful features in this pre, i.e. balance, mono, phase, hi/lo gain, more than enough inputs/outputs, etc. It's also a joy to use with a large, readable remote-controlled volume display in fine increments. As noted, the tubes are run very conservatively and produce almost no noise. Reliability is also first rate. This is a very easy tube preamp for any music lover to own. It can assimilate easily into most any system and deliver its special magic immediately.
Herron VTSP-3A
Hey guys, I just got this preamp in my system and have only used it for 5 hours. However, I don't have to wait for burn in or more evaluation time to tell this compenent is absolutley outstanding. The VTSP-3A is the new version and it has over 50 changes from the VTSP-3. I got my system sounding really good before the arrival of the Herron, but the Herron has really brought my system to life. Heck, the VTSP-3A has had the most postive impact on about every aspect of sound in my system than any other electonic compenent I have ever bought. I feel like the Herron is letting me hear the potential of everything else in my system. I thought I would make this post since I'm not sure if a lot of people know about Herron. If someone is in the market for a top of the line preamp, they may want to at least consider this one. For the record, I have no affliation with the company, I'm just a VERY happy owner.
