Of the 3 that you mention, the Herron VTPH-2 is probably the best option, and maybe overall in that price range. One more option that I'd consider in that range is the Allnic H-1201.

Buy used so that you can easily trade it out if it is not a big enough improvement for you. Take a look at K&K if you can build it yourself.

I'm in the same boat, Rkbcpa55. Listening in the store doesn't help much, as your system will be much different and the room setup could impact the sound. That said, based on reviews and hearsay, I've never heard anything but great things about the Herron VTPH2. In fact, this is the one I will get when money allows. It seems to be the quietest and most dynamic/musically engaging Tube phono stage under $4k. I also have the VPI Prime Turntable and Ortofon MC cartridge. I've called Keith Herron and Oswaldo Martinez from Let There Be Sound in Weston, FL - I would highly recommend calling Oswaldo, as he is very knowledgeable with the VPI Prime and the Herron and loading. he will answer all questions and gives great after care service if you purchase from him. Just google "Let There Be Sound" and he will be a great resource if you run into any issues. Tell him David from Pittsburgh sent you!

Quicksilver makes an outstanding phono preamp for under 2 grand.
