summit mpc 100a

Hi all, I want some advice on the pre-amp.

Neumann Microphone u87ai + Summit Audio MPC-100A

or

Neumann Microphone u87ai + Vintech X73i

How do you think that version is better? ...

We have possibility to acquire Summit Audio MPC-100A at a good price ...

Is the preamp compressor an electro-optical ?



Somebody have experience with this combo ?



Thanx,
