Ah, so you are looking for an HDMI in/out version of the 4 channel Flex. Send MiniDSP a request. You never know……
it seems one could easily do this with existing hardware, but it would not be a one box solution.
My main application is to use windows/mac laptop, or desktop and JRiver. Can actually get by without the hdmi output, but it would be nice to have that option too, especially for my DSD files.
