MOTM

I have read a lot about using certain preamps and compressors to
record all types of mics and instruments.
Such as the NEVE 1272, API 512, UREI 1176, etc. 
I was wondering what is the best for a semi-dark, clean,
sound that replicates MOTM sounds well.
I have no clue if you even should use a preamp with
a synth. 
I am using a small Mackie 1202 board to a MAC G3 AV model using the
RCAs out of the stock G3 audio card.
Any ideas for the best solution is greatly
appreciated. Thanks!
