I was just considering doing the updates, I haven't yet. Let us know what EMM Labs says when you contact them about this!
EMM TSD1 DAC2 Software
I have the TSD1 and DAC2 combo. They performed flawlessly. Then, I installed the most recent software updates for both, and lost fiberoptic connectivity between the two units. The AES/EBU connection works fine, as does everything else. I'd be curious to hear about other experiences with these particular updates.
