I've been using a Herron VTPH-2 for a while. I haven't heard anything as good, nothing better. Prior to the VTPH-2, I was using a VTPH-1mc. It was excellent, but not up to the VTPH-2. As I said, I haven't heard anything as good as a VTPH-2.
The VTPH-2 has an advantage of being "cartridge output neutral" since it has inputs for high output carts as well as low output carts.
Did I mention that I haven't heard any phono stage as good as a VTPH-2?
Herron Audio is very easy to work with and has an outstanding product line. Herron Audio would be on my very short list of manufacturers to use.
On the table side, have you listened to a Classic 2 or Classic 3? And I understand the 3D arm on the Classic 3 is a combination very hard to beat (though pricier than the Prime).
