"...you are saying ALL audiophile ethernet cables cause hum."

Not at all but any Ethernet cable with its shield terminated at each end to metal RJ45 connectors CAN cause ground loop hum in some systems. That was proven right here in the Asylum. As it turns out many such audiophile cables CAN cause ground loop hum too.

" And if noise gets to the dac it certainly seems audible."

Seems is the operative word. A controlled test might include an Audio Precision analyzer at the output of the DAC with:

#1) a length of cheap CAT5e cable going to the streamer

#2) same length high-end shielded *CAT7 or CAT8 cable to the streamer

Measure 'noise' at the output of the DAC with Audio Precision analyzer and compare the two cables. Has anyone done such a test? I'd like to see it out of curiosity. And even IF the high-end cable measures better it won't matter because the SNR is already well below what's required to perfectly extract the data.

*CAT7 was never an officially recognized standard and in fact CA6A is the better cable.

Look at all the bogus technical marketing speak. None of it even matters for the intended application:
