best phono preamps?


I heard the Jadis JP 80 MC and I was very impressed especially by the phono part. I have seen that Jadis builds a "only phono preamp" the DPMC. Any experience wih it?
which other phono preamp do you recommand?

my system:
Kuzma Stabi (looking also for new diamond)
Jeff Rowland Capri + monoblocs 501
Infinity Renaissance 90
clavil
Einstein Turntable's Choice is a must audition phono stage if you are after the best.
Hands down best I have heard, (do not own) is Doshi Aalps (sp?). I have not heard any of the above except the Steelhead, at a show, which is also VERY impressive.
Just bought the Art Audio Vinyl Reference. Wow what a difference that made in my system. One of the best I've heard.
