USB I2S and SPDIF for B3 SE Pro

[stephen1212b]

Which would be the preferred way to have both USB to I2S and an SPDIF inputs on the new B3 Se PRO?

Amanero Hermes Cronus provides USB to I2S.

Option 1 would be to use the OPUS WM8804 and an OTTO to switch the two I2S sources feeding the DAC.

Option 2 would be a single SPDIF receiver connected to the on board comparator and a switch to have the DAC select input.

Thoughts?

Option 2. Kinda what it was designed to do.

Do you still offer a single SPDIF transformer input? I can’t find one listed on the site.

I do still have them, but they are not listed on the page. I'll fix that.

It seems silly to have the wonderful isolation of the Amanero, Hermes, Cronus combination and then directly connect the ground of the SPDIF input to your secondary source. I am using only the input isolation transformer and tapping that to feed the SPDIF on the Buffalo III Pro which continues to provide the loading and level transition. A single switch works glitch and pop free to select between inputs and all grounds remain isolated. I highly recommend adding an input transformer for the SPDIF side of things for the lowest possible noise floor.
