I agree with the two Atma-Sphere recommendations. Ralph told me a while back his preamps were originally designed specifically for phono playback. He later added line inputs because of customer demand.
I've had an MP-1 Mk3 for a couple years now and as much as I enjoyed my previous CAT w/phono(all 5 of them), the MP-1 blew it's/their doors off; that's no exaggeration.
I hear good things about Doshi and a friend owns VAC so I might consider either of them if I weren't so happy with my MP-1.
One other thing worth considering, if it breaks, will the mfr. still be around to fix it? Atma-Sphere's been around for quite a while and has a great reputation for reliability.
