I’ve always been a fan of Nexus products. I mentioned before that when a product is good, I buy from it until it fails. The power supply was dishing out one of those obnoxious high-pitched squeals that really drive me nuts. There is another one of these units in my desktop machine that I’m typing this on right now. There’s no such noise coming from that one. I’m assuming this is a defect and am going to try to get a manufacturer replacement. We’ll see how that goes.
