I contacted Keith about acquiring a VTPH-1mm, long after it had been superseded by the VTPH-2. My research on the phono amp had informed me that most of the improvements introduced in the VTPH-2 were to it's mc section, which is of no significance to me---I use only very high output (5mV!) pickups.
Keith just happened to have in stock a traded-in VTPH-1mc, which he offered to convert to a -1mm for me. Sold! While he did that, he went ahead and made a few upgrades to the -1mm's circuitry, one's incorporated into the mm section of the VTPH-2. I had him set up the amp for lowest gain (42dB)---accomplished via the choice of tubes (12AX7 vs. 12AT7), but he also sent along the tubes required to create 44dB of gain, just in case. Whatta guy!
There may be "better" phono amps available, but at what cost? My system is a modest one, and the VTPH-1mm is certainly not it's weakest link. Creating a balanced system is the key to sonic and musical satisfaction, and I'm quite happy with my Herron VTPH-1mm.
