Could any of these also be used as a switch for SPDIF inputs? I need three switchable inputs to one output for my TV, SMYTH A16 Realiser, and (contemplated) miniDSP Flex into my OCTO Dac 8 Pro and all three of those inputs MUST connect to AES/EBU Input No 1 for the Octo to recognize it's receiving digital signal. Since spdif cable terminate in RCA plugs, it seems to me one of these ought to work.
