Update: I've left the irDAC on for the past week solid. Yep, definitely open, clean, detailed, sounds nice. I definitely have more than 100 hours of break in time on it and it sounds even better than when it had 10 hours on it.
0s/1s or not, for anyone who is wondering like I was about a new irDAC, it's true, there definitely is an initial break in period on this device and for whatever reasons, it sounds better as it gets more time or heat to it, whatever the case may be. Sounds nice, smooth, clean, controlled, they way it's suppose to be. Even with AppleTV, it sounds pretty good for compressed audio content by simply running it through the irDAC. I run the irDAC into my integrated Tube amplifier and overall I'm pleased with the results. Is it as good as a quality mastered CD, no, but for regular listening it's definitely "good enough" for me. Glad I purchased the irDAC.
