You're right to be sceptical of random people making random comments on fora, but suffice it to say that with ~40 years in the computer industry, the last 30 of which have been deeply involved in the development of industry standards for Ethernet, WiFi, and LAN switching, I think I have a somewhat better than average knowledge of what does and does not affect the operation of a digital network, whether it is used for audio or not. Putting directional arrows on your Ethernet cables, and making the conductors out of silver (for example) aren't on my list of things that matter a damn, other than to give the punter the warm feeling of having bought a pretty new toy.I am not convinced that random people like yourself posting to this forum understand computer audio any better than I do. You may well have a track record in designing state of the art digital audio equipment, but until if and when I find out you have some sort of track record and expertise, why should I think that you know more than I do?I don't regard a reputable brand such as Audioquest as 'foo con-men'. I haven't spent a lot of money on my computer audio server and associated cables, and in fact I have spent much less than the average computer audiophile with a Windows tower or Mac Mini or whatever.
We're deep into "The Emperor's New Clothes" territory here.
