Phono preamp comparison/Pass,Herron,Avid


I am shopping for a new phono preamp to mate with my Basis 2500/Vector 4 arm combo. The cartridge is a Dynavector xx2 mk ii . I have narrowed my search to a Pass Labs XP-15, a Herron VTPH-2 and perhaps an Avid Pellere. Research in the analog forum reveals a couple of recommendations for the XP-15 and xx2 combo, but I have found no direct comparisons of the Pass and Herron units. I find very little on the Avid either but it is a newer unit. I would be interested in hearing from you if you have one of these units on why you chose it and how it impacted your system. I have Pass and Avid dealers in my town but neither has a unit to demo presently. If you are wondering what my goals are, at this price point, they are transparency, neutrality and low bass fidelity.
Thanks in advance for your posts.

Yes, please let us know what you think of the Herron VTPH-2... What did you think of the VTSP-3A (pre) and the M1A's?

Great choice. Dont be afraid to run it wide open without any cartidge loading plugs. I think my VTPH-2 is the longest tenured component in my system. It sings with my Benz LP-S cartridge.
Teeshot, how did the Herron work out? Is it providing the bass control you sought? Did you ever audition the Pass in comparison?
