I also want to say I still love the DAC10, it is simply wonderful.
I had issues with one remote until I realized that the angle at which I pressed on the buttons was the key. If I press straight down toward the side with the lettering, it always works perfectly, 100% of the time. If I press inward toward the center of the remote, or away from the side with the lettering, it fails. Perhaps a property of the switch operation at work here?
I had considered replacing the remote, but not any more.
The features, size, sound quality and price make it one of the very best stereo control units out there. I have them in 2 systems and they are wonderful.
