I read the literature page (link).... The verbiage is confusing, I'm not sure whether the DAC upsamples to 24/192 or uses "8x oversampling".... It mentions both, but can't use both, unless it's a selectable option.If the DAC does upsample to 24/192, the issue is likely with the output clock. Either defective or poorly designed/implemented. If the DAC does NOT upsample to 24/192, I can picture a DAC having jitter issues if the PLL isn't robust enough to handle signals from a PC (as opposed to a disc transport). Or if no PLL is used at all.
I would try other digital signal sources (transports rather than PCs) before jumping to any conclusions.
