Just noticed your Apogee One, nice portable solution.
Another thought, what I used to do with my Mackie was put the Alt-34 in to my Apogee Duet inputs. That way I could press alt 3-4 for whatever I wanted to record, through two nice preamps / converters.
Unless you need to record 14 channels at the same time, this is a cheap and high quality solution, with minimal change to your setup.
