Kevin told me at the 2011 RMAF that he was working on an all-out outboard phono. It didn't sound like it was going to be released in the very near future, but if you are patient that might be worth waiting for.
I take exception to Mulveling's comment that "you're going to experience at least a bit of hiss with any tube MC phono stage, even with a step-up." My own tube phono which uses a stepup feeding a D3a pentode and 5687 phono preamp is a very quiet phono preamp, considerably more so than the 5 or so solid state MC phonos I've tried. It all depends on the design and type of tube. You're not going to get that kind of black background with a 12AX7 for instance.
