Just purchased a Belles 150A Reference amp. Watch should my preamp be..

My system is shaping up as follows: VPI classic 1 (JMW 10.5), Dynavector Karat 173D cart, Maxxed Out/Cary SLP-98 or other tube phono stage in 2-3k range, preamp?, Belles 150A reference, Epos m12i speakers. The system is probably too good for the Epos m12's, but I want the flexibility to upgrade those at some point. What preamp should I try to pair with the Belles?
