Sorry to hear about these difficulties. I have been using this device for over a year now with absolutely no problems. I use it primarily to play music but have used it with videos, both from DVDs and streams, though with my set-up sound for those those go in by spdif. This is the first I’ve heard about any extended difficulties either with the 005 or the earlier 004 which I had for 6 years, also with an Amenaro board. There was one problem reported here installing the Windows driver (fixed immediately) and some had questions about the DPLL settings.
The first thing to determine, I think, is whether your 005 is defective. It would be the first defective 005 or 004 I would have ever heard of, but it is possible. Second, you say that you have been playing it for 3 weeks. That might still not be a full break in but it certainly IS enough for you to know how it sounds. If this $3K DAC it doesn’t satisfy your needs far better than a $1K DAC and you have the opportunity to return it, then perhaps you should. After all, SQ is the bottom line. Same if it is defective.
You wrote earlier about your concern regarding galvanic isolation which has principally to do with the relationship between a USB input device (like a computer) and the USB receiving board, like the Amenaro. You sounded very much like you know exactly what you wanted. The Amenaro is one of the two promenent boards used in most of the best performing DACs. I would have supposed, based on what you wrote, that you would have investigated Amanero to see if it would meet your requirements.
At this time I use a SOtM device as a DLNA bridge betwen a small lap-top computer running JRiver and the DAC. However when my 004 was new, the computer was plugged directly into the DAC. There was absolutely no background static at all. There was no noise that I could hear at the time, though when I added the SOtM bridge it did sound quieter. The DAC’s behavior in that regard was exactly as it should have been IMO.
You should have no driver problem at all. But that’s a local issue between you and Windows, I assume.
There are plenty of folks here who would be happy to help, and I’m sure they’ll be chiming in. But as has already been suggested you need to describe your set-up in detail.
Good luck in dealing with the issues.
