Help with preamp choice please

Hello all. I'm strongly considering upgrading my preamp and based on reviews (few high end dealers hereabouts) I've just about narrowed the choice to a Rogue Audio 99 Magnum or a Sunfire Classic Tube. I've already got an outboard phono stage that I like so that's not really a consideration. If any A-gon members have compared these two units I'd be very interested in their impressions. If anyone knows of a better choice (Amplifier to be driven is a high input impedance solid state) for about that amount of $$ please don't hesitate to say so. Thanks in advance for any and all responses.
