Hey guys, I'm looking for a pre-amp as the front end to my projectmix I/O which I run with Pro Tools M-Powered. I want to record vocals, guitar and bass for metal and pop-rock. Right now I'm looking into the Focusrite ISA 220 w/ digital card and the SSL XLogic Alpha Channel. Can you tell suggest one of these or another one I haven't thought of? One of the big sellers with these is I feel I will get higher quality A/D with these when I use the digital outs. So keep that in mind. Thanks for the help.
