hungrych Posted December 17, 2008 Report Share Posted December 17, 2008 So I got my Aura Note USB DAC/CDP/Integrated and it sounds great, but whenever I have it plugged into my computer via usb I get alot of noise. I assume it's related to the computer in some way, as more activity (scrolling, opening programs) directly affects the noise. It doesn't even matter if I'm using the usb input or not, I can be playing a cd and the noise will be there unless I unplug the usb cable. What should I do? Would a usb hub or something help? Or maybe a shielded cable? I'd appreciate any suggestions. Also, I've used a few other usb audio devices and never had this problem. Quote Link to comment Share on other sites More sharing options...
Dusty Chalk Posted December 18, 2008 Report Share Posted December 18, 2008 Yeah, but have they ever been electrically connected to the CDP before? Quote Link to comment Share on other sites More sharing options...
hungrych Posted December 18, 2008 Author Report Share Posted December 18, 2008 What exactly do you mean? It's not usb powered or anything. Quote Link to comment Share on other sites More sharing options...
Dusty Chalk Posted December 18, 2008 Report Share Posted December 18, 2008 Yeah, but if there's noise on the line from the computer, wouldn't the electrical connection "conduct" it through the source to the amp? Quote Link to comment Share on other sites More sharing options...

deepak Posted December 18, 2008 Report Share Posted December 18, 2008 Have you tried a different computer with the CDP to see if it's just the CDP being extra sensitive to noise over USB or if your computer is the culprit? Quote Link to comment Share on other sites More sharing options...
Dusty Chalk Posted December 18, 2008 Report Share Posted December 18, 2008 get a USB to optical adapter, assuming the DAC has an optical input, will probably fix the issue.I second this -- at least as something to try, it'll help isolate (ahem) the problem.

naamanf Posted December 18, 2008 Report Share Posted December 18, 2008 Lots of Jews of Eastern European descent are lactose intolerant. No problems with the moo juice here. Cop out if you ask me. Quote Link to comment Share on other sites More sharing options...
hew Posted December 18, 2008 Report Share Posted December 18, 2008 Also, I've used a few other usb audio devices and never had this problem. If that's the case then it might also be the dac itself that is faulty or just extra sensitive to noise. I would call the manufacturer to see if they have any ideas. If it is an inherent design problem they would have encountered other customers with the same complaint and may have a simple solution.

Sherwood Posted December 19, 2008 Report Share Posted December 19, 2008 The hub isn't a terrible idea, as I've heard reports of that working before. The shielded cable will do nothing for you, unfortunately. Or, of course, sell it to Mike and deliver it back into the great "Circle of Gear" Quote Link to comment Share on other sites More sharing options...
