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.

Sure, but speaker control is in the design. Big transformers, large banks of ps caps and the like don't necessarily make an amp more capable of controlling a speaker.
Well I think the only way to satisfy my curiosity is to try his components in my system.
Based on the fervent recommendations here and my listening in the Herron Audio room at AXPONA, I ordered a VTPH2 from Keith. If I am dissatisfied with it for any reason, which I highly doubt I will be, I may get a Pass XP 15 to try. I ended up ruling out the Avid Pellere because not only could I not listen to it at AXPONA (it was in an Avid room but not hooked up)I could not get a satisfactory price from Music Direct for a demo unit. Once I have a chance to audition the Herron in my system I will post a review. On another note,I have been very satisfied with the Dynavector XX2 mkii cartridge I have had for a month now and will be interested to see how much more musical life and content is revealed with the phono stage upgrade.
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?
