I would like my DAC to support both coax and Toslink SPDIF as well as two different USB modules (Amanero for now, and the TPA USB module when it becomes available).
Let me try and help.
4x SPDIF inputs use this board
S/PDIF 4:1 Receiver/MUX Module
you can use RCA or BNC or one input can be configured for XLR-AES input.

you would then need a switch board (mux) like this
OTTO-II 2:1 Switching Module

this would allow you to switch the output of the above CS8416 based SPDIF input board to a USB input board like this

The USB DAC/Receiver

Now if you wanted TWO USB boards. then things get tricky as you would need 2x of the OTTO-II boards configured in a tree to get 3 inputs. which makes a case for a 4:1 or 4:2 I2S switch board.

May i ask, when you decide which way to do this, and then when PCB's will be avalible?
Why i ask, is because this is the thing i wait for, before i'll order a complete dac-kit with everything.

I have pretty well settled on approach #2

I think this fits the broadest use case.

This module will mainly be used to switch 4 channels of SPDIF into B3SE directly (since it has it's own level converter) - or - into B3 with the single SPDIF level converter in-between.

For switching PCM/DSD it would be very rare to need to switch more than 2 sources - so the OTTO-II is a perfect choice.

For B3SE you could easily wire both this new 4:1 module and the OTTO-II at the same time.

I plan on finishing up the layout this weekend, and ordering the first run then.

I will post the layout for you all to peruse.

Cheers!
Russ

Sounds great, looking forward to see how you have made the layout.

Dear Russ,
for the less expert I kindly ask you:
which will be the practical differences between this new board and the actual S/PDIF 4:1 MUX/Receiver with CS8416?

Will you just change the IC with a more perfomance one and redesign the board with new feauters?

I'm asking also because I just bought the S/PDIF 4:1 MUX/Receiver...

Thx in advance,
GM

The difference would be just that this module does no level conversion at all.

What is it you are trying to get working?
