Isn't the reason that, at least when this was on an SACD format, it was encrypted so all hardware had to match the 'closed system' protocol with no digital output that could be accessed outside of that closed loop? E.g., like original and Blu DVD?
Can an HDMI output be converted into something a USB input would accept?
My disc player (Cambridge CXU) will only output DSD files via HDMI; is there a way to convert this to USB, or optical, so I can send it to a DAC that doesn't accept HDMI?
