I'm not entirely sure that I understand options #1 and #2, so I'll just weigh in with the functionality that would make my life easier. Ideally, I'd like to have a single board that allows for up to four inputs (each of which can be SPDIF/PCM/DSD) and one output. Is that even possible? 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!

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

Any chance to get mine working? I still haven't had any luck.

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

What is it you are trying to get working?
4:1 receiver with the current source.
Power seems ok but the receiver can't lock the signal, not coax nor tos link
Pics were uploaded on your forum a couple of months ago.
Thanks!

Mavallarino this module (the subject of this thread) does not even exist for anyone other than me yet, so I am not sure what you want me to look at... Is it a SPDIF 4 (which is a quad level shifter)? If you have a thread on the support forum, just reply so it bubbles up to the top, and I will look at it for you. 🙂
Cheers!

Dear Russ,
is it kindly possible to know approximately when the the 4:1 Mux for Buffalo III SE will be ready?
Thanks a lot!

The design is finished and will be included in the next board order which will be in a week or two.

Hi Russ,
I sent in the photos using the feedback (AT) address.
Have you had the chance to look them over?
I can have the boards shipped to you if you are able to test them.
Please let me know.

Dear Russ,
any update about availability?
Meanwhile: to switch between 4 spdif for the - BIII SE - do you reccommend to buy:
- the "old" MUX 4:1 CS8416 or
- the BIII 4-Channel S/PDIF Level Converter or
...better to wait this dedicated one when ready? 🙂
Thanks!
best regards,
GM

The "4-Channel S/PDIF Level Converter of the BIII" is not a switch. It simply converts four channels of consumer-level S/PDIF to TTL-level S/PDIF.
I had to pull the original order (because of a design change), but I just ordered a batch of 4:1 mux boards. They will be here in a couple weeks. 🙂
