I see a couple of Herron VTPH-2a users have moved on to different phono stages. I use the VTPH-2a. A couple of years ago Keith called me and asked if I was still interested in his phono stage? Previously he told me that he was done making the VTPH-2a. He was retiring and was running low on the components to assemble them. I said yes! He told me that he found enough extra components in his stash to assemble three more. He also said that he’d considered mine a "VTPH-2ae,” e for enhanced. He didn’t get technical regarding what he changed in it but said he thought it was a slight improvement in sonics.
I’ve been very happy with it. I’ve only compared it to one other phono stage, a Pure Audio solid state which is 1-2k more expensive than his was. I was surprised that the gain was greater with the Herron and sounded much more musical than the more expensive Pure Audio.
I’d be interested in hearing why past VTPH-2a users moved on? @dodgealum, @dwette My next move is to add a 2nd tonearm with a mono cartridge and use the MM inputs so I can use the switch on the back of the Herron to go from one tonearm to the next.
The only fault I have with my current set up is the volume dependent hum I hear from the tt front end compared to other sources. TT front end: TA Zeus MC cartridge - TriangleArt 12” Horus tonearm - TriangleArt Maestro tt - Herron VTPH-2a - Cardas Clear unbalanced cables to the preamp. The hum is much more noticeable when I have the lights in the listening room turned on, I use low voltage lights in the room, there’s a small transformer in the outlet box for the low voltage lights that I think is the main culprit for the noise. Once I turn off the lights the hum is greatly diminished but when I turn the volume way up I can still hear the hum with no record on the platter.
