Thank you, I wasn’t clear, I meant from the source to the upscaler.I wouldn't have thought so. Optical I think, is limited to 192kHz and the Blu2 "magic" occurs at 705.6/768kHz. So If your DAC cannot accept a 705.6/768kHz digital audio signal then the money spent on Blu2 will not be getting the best of what it can do for audio....as usual YMMV.
