Phono Peramp Choice/Pass, Herron, Avid

I am looking to purchase a new phono preamp to use with my Basis 2500/Vector 4/Dynavector XX2 mk ii analog front end. After much research, I have narrowed my search to Pass XP-15, Herron VTPH-2 and perhaps Avid Pellere at a slightly higher price point. In researching the forums I see a few recommendations for the Pass with my cartridge. What I do not see is any comparison of the Pass and Herron nor any discussion of the Pellere, which is a relatively new unit. If you have experience with these units let me know how you chose them and how they have fit with your system. My priorities are transparency and neutrality of tonal balance.
