The rechargeable AA issue is definitely a bit sloppy, but so far everything else about this deck is extremely promising. I think as soon as we determine a solid solution for making a custom SPDIF breakout cable, I will pull the trigger. Having a small 2-channel recorder with digi-in will really help me avoid the dread of using my AD2k+. Will make it easy for me to only run two channels and be clock synced with whoever else is at the show with me.
Unfortunately, I checked pretty much everywhere on the intarwebs and couldn't find a single high-quality right-angle 2.5mm TRRS plugs available. Everything out there is straight, pre-molded plastic garbage.
