I was thinking that if I keep my 18i20 preamps as low as they go, that it would keep any coloration from my 18i20 as low as possible and the primary conditioning would be from my ART Pro II that's connected to my 18i20.
I find that I must use the preamps in the 18i20 in addition to the ART preamp to get my input signal to my DAW up enough.

Any advice is appreciated.
