I heard the 324 at a dealer place & felt it was a very good phono pre-amp.
I liked the flexibility. Its everything one could want for
however I wish it had that tube bloom in the midrange.
I haven't heard the 88pb.
But the 324 betters the 834p in every way except for the midrange bloom found in the 834p which i wish the 324 have.
I speculate that the 88pb has the combo of the 324 and the 834p.
