Thank You
Yes it can, but it is not usually optimal for several reasons.

(This is assuming I have 4 IVY IIIs at the other end to handle the 8 outputs.)
You can connect spdif to spdif input 6, 7 or 8; you connect the 8 channel I2S to the respective pins and switch between I2S input and SPDIF 6, 7 or 8 input

I bought a Placid HD (single) and when looking to find the BOM could not find it (link not working), any chance you can share the file?

Thanks

I will get it up there in a few minutes. It's the same as the top half of the BP supply.

I am assuming the Sidecar does not perform this function, and I would need to build my own switch?

I am planning to build a dual mono version of the Buffalo III. Am I correct in assuming that I will only want 1 * 4 input SPDIF and 1 * sidecar to feed both BIII's?
That is correct. You wire both BIII's in parallel to the Sidecar. The on-board controller will set the registers for left/right and dual mono (based on the switches). Russ stated running parallel should work for up to 4 boards for both the inputs (Sidecar) and the Volume pot (for the on-board Volumite).

(This is what I gather from reading the datasheet) In theory you do not need sidecar. The Sabre chip has 8 input lines. The last 3 are assigned (and multiplexed) to spdif. The first 5 lines can handle both spdif and PCM (I2S). If the firmware allows selecting between I2S and SPDIF (say spdif 8), then when selecting spdif, the I2S pins are ignored and when selecting I2S, the spdif pin is ignored.

The manual for BIII is not yet available, so I don't know what is the facility (dip switch combination) to do this kind of switching.

You still need sidecar because you will need to switch out the bitclock or you will confuse the ES9018 about what it is receiving.
