Well, I still own it, but to be honest, yes, it has been replaced by a very simple solution:
I currently use an all Audio Consulting silver rock passive pre into MIPA amplification: I am a very happy man!
Looking to sell the Audiopax, despite the fact, that the new power unit made it a completely different animal, somehow it is one of the most colourfull units i know, like autumn leaves - whereas the Silver Rock strikes me as a little brook of water..
I might actually prefer the Audiopax with large Orchestra, but my own interest is really chamber music, piano, and some jazz.
