ok I will chime in I guess...

for your/any mic Centrance makes a clean mic interface called Mic Mate Pro.
I love mine, its quiet, has decent pre amp, runs 24 bit and will run with
Indamixx at 2msecs in Jack.

I am pretty sure Robin Gareus wrote in another respone about 'on soundcard'
buiilt in processing with UA EX 25/ others and basically said all that stuff
does not add up to a hill of beans.....

As far as pre amps in low cost mass market audio devices such as M Audio and
Presonus that's all definitely a marketing scam
because when we were making Trinity DAW with Echo Audio I got to look at
every mfg. design and exactly what they ALL put in these devices and in
EVERY bill of materials BOM as a mfg you have 2 choices when building a
sound card.
1) The .80 cent part from Maxim or some of the others
2) The high end uber boutique part that will cost you some serious coin

What I learned from Milo at Echo is all of these products have noise but
Milo is very good at  placing other parts on the circuit to cancel and kill
noise.  Just ask Daniel James at 64stduio because he has one of the original
Trinity DAW units and its so super quiet ( you think its not running)

Again I would suggest going with UA EX 25 because I think I read in LAU that
you can get 24bit mode going on the card.

Sorry to break anyone's heart with the 80 cent part fact but that's the tale
of the tape.

However, now that I know where the difference is measured between audio
cards, I would choose Echo because Milo is at the top of his game, AND Echo
has been Linux friendly for quite some time.

Thank you
