What I’m trying to achieve--- I have two sources, one coax/spdif out, the other AES out, both into the Gaia/Aether combo, then I2S into the DAC. I have a new, third source with I2S out. Hence the need to juggle all these outputs into a single I2S input into the DAC.
At this point I’m considering running the new I2S device into a microDDC/SBooster LPS combo, and manually changing the DAC inputs depending on the source used.
I wonder if an HDMI switcher is available, so two HDMI connectors in, and switchable to which one is output. But uncertain if this might this affect sound quality.
At this point I’ve done more research and am pretty sure no device exists that has all the inputs I need (coax, AES, I2S).
I heard back from Denafrips support that they will relay my feedback to add an I2S input to the Gaia, for whatever that's worth.
