Wow. This thing is beautiful. I'm glad I stayed in today on the off-chance that it would be delivered.
Gotta start posting somewhere, so as mundane as it is, I'll address the concern of a buzz / hum / RF noise while charging, and in my case a flickering light, that I saw, oh, a hundred pages back. This thread moves fast, so here's my experience for imminent posterity. The noise came immediately upon plugging the unit into an Apple knock-off 1A wall charger. The sound was intermittent and had a few variations, with the charging LED either on, off or flickering. It's a dreadful first experience with a gadget to have one's excitement knocked out of them over worry about the battery and then rush to a forum to see what may be the problem. So, after that, I plugged it into my Anker multi-port "smart" USB charger, which I didn't use at first since there's no indication of its intelligent allocation of amperage, and the noise was gone.
True story.
Perhaps the knock-off was just under 1A. Anyway, the first post I read mentioning this charging noise was angling for a decision to return the unit and a damper on my excitement, so lest this was covered by Chord in the meantime, to those with the same concern: I doubt the noise indicates any issue at all. Just try another charger till it's quiet.
Looking forward to the warmth this puts out over the winter.
Hoping it does well with my HE-560 so I can sport some expensive earmuffs too. My portable dac/amp wasn't meant to be ambitious, meant mostly my Etymotic ER-4P (adapted to 4S) and iPod touch, but being underwhelmed by the JDS C5D, which I admittedly didn't give it much time, I thought I'd splurge on the Mojo to be more impressed and have a chance of strolling around with the HE-560.
