Please anyone don't take this the wrong way.. I'm really just nitpicking. Probably most people don't care or even notice little extra background noise, and it's pretty impossible to hear with headphones blasting anyway. I'm just curious if it's a single (double) incident, why isn't it completely silent.. but I'm not wearing my headphones all day and any unnecessary noise annoys me. But things like powering it first time making a super loud whine, I thought it was broken immediately, but perhaps it was charging caps or burning in whatever, it settled down.. things like that don't build up confidence.
