Conrad Johnson Premier 15/2 Phono Amp

Opinion's about this phono amp? I use it in combination with a lyra titan i, uesugi trasformer 5 L, passive preamp audio tekne 9701, cat jl2 and eidolon diamond's.
I found it sound's really wonderful... but since I am searching for a definitive device, I am asking if there is a better phono preamp...
Thank you!
