Separates or not?

I'm redoing my office system.  I just bought a pair of Maggie's, the 1.7is.  I have a Bryston 3bnrb for amplification.  The question relates to preamplification.

My budget is around $4000 give or take.  I need mc/mm phono amplification and line level preamplification.  I am looking at new or demo. I would consider used only if it has a significant transferable manufacturer's waranty.

I have a Michel Gyrodec Ii with SME 309 arm, and several different low output MC cartridges(.2-.4 mv output).

My question is, given my needs, would I get better bang for the buck at this price level by getting a preamp with an integrated phono stage, or going with a line level preamp and a separate phono stage?  

Thanks.
