Each time I play a DSD file (64, 128) from my Aurender X100L (USB output) I get intermittent music drop outs with high frequency noise. This occurs for a couple of seconds, every 15 to 20 seconds, regardless of whether I play DSD direct or DSD Dop. Using different USB cables did not resolve the problem. Playing PCM files is fine.

All firmware is updated on both ADI-2 and X100L. Bit test confirmed correct.

I contacted Aurender who were able to check online that my X100L has no hardware issues. They suspect the problem is a general incompatibility/miscommunication (firmware issue) between the Aurender and RME ADI-2 DAC.

The Aurender Technical Support Manager has had no success getting a response from RME.

I’d appreciate some relevant technical information on how RME processes DSD files via USB so that I can pass it onto Aurender tech support. Or a reliable contact at RME tech support so that Aurender can liaise directly with them.

Thanks.
