Thanks!
I need 8 channels, so it looks like I will have to put the miniSHARC and the Buffalo III in the same enclosure...

I use a pair of them to send 4 I2S stereo "channels" + clocks

Sorry, I was referring to data lines, not I2S channels, but coincidentally my answer is the same, as long as you do not need to supply master clock (MCK).

If you mean channels of I2S data, then you have:

Line 1: BCK
Line 2: LRCK
Line 3: DATA (2 audio channels)
Then another line for each 2 audio channels of I2S DATA.
Plus one line for MCK if needed.

Each Teleporter drives four lines, so for eight channels of I2S data, you need to run a pair of Teleport transmitters and a pair of receivers.

My old rack-mount DAC interface has been down for a while now. I was waiting for the USB interface but now with several non-TPA options available got more serious - only to realize that multichannel synchronization and/or DSP filtering on the XMOS chip are far from assured.

So I'm simply going to hack I2S from the ICE1724 chip of the old pci card right inside the PC and send it out using teleporters. I hope it is as easy as it sounds! A couple of questions: a) 5V from the computer PS OK to supply the 2 transmitting teleporters? b) any extra shielding recommended inside the PC chassis? The wires to the teleporter can be ~2" or less in length.

I did something similar with an Asus Xonar card. Worked well.
Powered Teleporters from PC PSU using standard molex connector.
(Have 4 Teleporters . 2 mounted on PC back plates and connected via ribbon cable to Xonar for sale, ready to go. If you are interested )

Thanks for that info. The convenient element of this (albeit old-school and short term) solution is that I don't have to change the ASIO setup nor the crossover filters/software. It should get me running with a SQ upgrade until better multichannel asynchronous methods are available. I already ordered new teleporters, though thanks for the offer…

I'm setting my source up to be able to switch between a USB-to-I2S device (Amanero) and an embedded player (e.g. BBB). The latter will reside in a separate box with its I2S output "teleported" (TM ) to the D/A.

Parts are ordered and I'm now trying to choose between the attached layouts.
Will the Teleporter offer adequate isolation (Option A), or should I play it safe and isolate at the OTTO's output (Option B)?

I assume you have another Teleporter near the OTTO for receiving...

If you want isolation, it seems to make sense to use layout 2.
