As the previous poster said, many people have raved about the Aleph P with the Aleph amps. I have owned this, and also have had long-term in-home auditions of the X-1 and the X2.5. The X-1, I thought, was phenomenal in every way. The X2.5 was very decent, maybe a couple notches down from the X-1. Both X preamps seemed to have greater clarity and detail vs. the Aleph P, and both are very dynamic. Any of the three would be welcome in my home.
Good luck,
Jeffrey
