Not only that but the simple act of unplugging one set of cables and inserting another destroys the subtle electric mechanical interface
Not sure what a 'subtle electric mechanical' interface is supposed to be. BUT Ethernet is intentionally designed to be hot plugged.
Let's take this to its logical conclusion however. Cabling is really meant to be a device of least damage to the signal. The thing that is going to be better than any cable is no cable at all.
Anyone here can test out if a generic cable is going to deteriorate SQ by starting playback and having someone remove the cable and see if SQ improves. Here's the thing: a cable can not improve SQ. It's a passive device there is nothing additive about it.
Preferably on a cable cooker
Anyone that has used any cabling long enough has cooked cables. What happens if they are using optical? We all have fully baked systems.
the proper directionality of all cables involved should be predetermined. Otherwise the whole exercise would be more than a little fruitless IMHO
What direction would that be? Ethernet is bidirectional. Think about how you want to answer that because it's going to take us into shielded data cabling and it's something I know a lot about since I've installed and designed countless networks from multi site office to heavy industrial (auto manufacturing and the like).
Is anyone here from the North West KY / Cincy region?
