I just got one of these recently, thanks to this here forum.
So far I really like it, but recently I've had issues. The first was it noisily crapping out a couple times, giving way to static after a loud pop. I'd disconnect it for a few minutes and reconnect it, and all was well. However, this is increasingly a problem. A couple times recently I have sat down at my desk to and put on my headphones to find a wall of static in place of the clean silence I expected.
All that said, I've been leaving it plugged in all the time. My assumption was that it would idle with my computer, and therefor not heat-up, puss-out. Instead it seems to always be cranking, and a couple times when I have found it in static mode, it has been incredibly hot, like first-en macbook-pro hot!
Should I return my unit, or do I just need to get used to unplugging it each day?
