Control 24 inputs or Digi 192 inputs??

[Al Rayder]

I am hearing the mic pres on the Control 24 (mk 1) are nothing to really get excited over and now that I will be using the Control 24 other than as a giant mouse for ProTools 10HD, I am curious if anyone can shed some light if I am able to just use the Inputs directly from the 192 for recording Instruments and Mics? I know I will need a db25 pin to XLR -or- 1/4 breakout cable. But what are the pros/cons from using the 16 Inputs I have from the 192 I/O vs. the 16 Inputs from Control 24 inputs... Would I be better off bypassing the Control 24 inputs? At some point I will invest in either an Avalon, Universal Audio or Manley pres, but for now, I would like to get some feedback on what I own now. Thanks.
