I've got 30+ shows on the C02, with NO ISSUES (aside from batteries going dead). Checked a few against a D-10 running as backup, and they're bit perfect.
The C02 DOES NOT RUN out of certain equipment, but the problems are real obvious (dropouts, pop's, etc.). Most notable - runs fine out of my D-10, not worth a damn out of my 3700. Same (bad) results of out a DA-P1. I run out of a LunaTech V3, and I'm to the point where I'm going to get a small Pelican case for just the TLM-170's and start bagging it with 1 EC-90, the V3, and the Nomad. Grace should have an Optical Out upgrade in a few weeks, for people running or considering a JB3 setup, that will sweeten the deal a bit...
