32 bit x 384000 Hz = 12.288 Mb/sec. per channel.
TB2 is capable of 20 Gb/sec. or 1626 channels at 32 bits and 384 kHz.
Or 4,340 channels at 24 bit and 192kHz!
Rest assured SOMEONE will claim they need more than that…
TB3 is 40 Gb/sec and unquestionably overkill. It is meant vor extra 4K displays and docking stations with multiple devices connected I would say.
That being said, TB2 is largely an Apple thing and I have seen very few PCs with it. TB3 and USB C is showing up on PCs now but there are adapters to TB2 available…
Overall, the AXR looks nice.
