Ohh yeah, one other thing. The 880EX uses 20 bit A/D converters. I believe the 1680 does as well. I've read a couple different things, some say it uses 24 bit A/D converters and others just say it has a 24 bit internal structure with 20 bit A/D converters. The older 880 by the way was 18 bit A/Ds. None of the v-studios are 16 bit.
