I second the Audible Illusions 3A recommendation or the Audible Illusions L-1 if you have an outboard phono preamp. Even though both preamps share the same linestage, I prefer the master gain control with one volume on the AI L-1 rather than two volume controls on the AL 3A. You can expect very good dynamics and transparency with both not to mention top notch sound quality.
The other tube preamp I like after trying many is the VTL 2.5. Try and find one with a tube phono circuit installed.
