Not the finished project, but nonetheless, a working prototype using a Metronome-Teleporter-DSP4YOU AVB Dongle combination for extracting room eq'd and low-mid-high digital xover outputs of the I2S digital streams from a DEQX unit. As you can see, the DEQX has 2 SHARC processors processing 96Khz in realtime.

The digital in for the DEQX will also be via the same AVB interface - meaning I can now stream multiple uncompressed channels over my home Ethernet network out to all of my Buffalo DAC's operating as quadrophonic 3 way monoblocks (tri-mono Buffs in each monoblock).

The AVB Dongle does 4 stereo channels in-out at 48Khz, but am now trying the XMOS XCORE-2 eval board which can do the same at 192Khz.

PS: When the Teleporters are all running off of the same power supply all the gremlins I have been experiencing vanish
