Interesting this ‘upgrade’ on Ethernet cables...I picked the brains of a very well regarded net cable installer and we got chatting about Ethernet cables in relation to hifi.. he reckoned as long as it was cat 5 cable he would bet his house & his kids there wasn’t a sonic benefit to be had anything else. Obviously I asked the question as it’s valid in this community... but there you have it. He works this with this stuff 38 hours a week. He laughed when I told him £££ Ethernet cables in hifi existed.
