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.

I just recently got an XP-15, but the VTPH-2 would have been my first choice had I been using a friendlier preamp. My Spectral preamp has a very low input impedance - too low for a tube preamp such as the Herron to drive. Tube phono stages have a very difficult time driving a 15 kohm input impedance. I tried the Audio Research PH-7 also, and this couldn't do it either. Bass was just a mess with both. Both manufacturers advised against this match. I mention this point only to point out that some consideration should be given to the impedance match.

I thought the VTPH-2 easily beat the PH-7 in a friend's system. It was amazing there. Another friend just got one last week. He's thrilled with it.

Keith Herron may be the nicest guy in audio. A bunch of friends own his products. He has taken incredibly good care of them.

Of course Pass ain't chopped liver either. The XP-15 replaced my Xono and delivered a tremendous upgrade - possibly one of the biggest step changes of all my upgrades. It's an amazing component.

I think you would be delighted with either the Herron or the Pass, though I'd give Herron the nod due to the way Keith's provided upgrades to his components over the years.
