Bride of Son of Zen for Mic Pre?

[blschuler]

I would like to build a high quality microphone preamp and wonder if The Balanced Zen Line Stage would make a good choice?

Some input capacitors would be required if phantom power is to be used.

Is there anything else I should take into consideration?

Here are some specifications on a mic I am considering:

The major problem is that the Mosfet are too noisy.

You could try a similar circuit using Jfets, although you
still might not get as much gain as you want.
