Help me put a system together for my son

One day out of no where my (future) daughter in law say's my son is collecting albums. I had no idea he had any interest in audio, let alone vinyl (must have been paying attention to my hobby after all!) . They are in the process of buying a condo where his system will be used. He mentioned that bass was not important to him and that he was more interested in good midrange system. So far I picked up a (new) Rega RP1 TT that came complete with tone-arm & Ortofon cartridge. I am in the process of acquiring a used pair of Magnapan MMG. Keeping a low budget cost in mind, what amp/ pre amp or integrated would you think would work with what I have so far. And, he will need a phono pre as well. He has no interest in any other source at this time, just a vinyl set up.
