Take your pick from any ethernet spec cable, Blue Jeans Cat 6A cable is a favorite from the states, I can’t recall the name of the ethernet spec cable from the UK that is popular.
Or if you want to throw money at the boutique streaming cable industry you have numerous choices.
Surely the consensus is more that people who use expensive cables believe they’re worth it, and those who don’t don’t? (Latter don’t necessarily think they’re rubbish).)
Digital Cables carry information as 0’s and 1’s.
Analog Cables carry information in a waveform.
Being a Naim user I use analog Naim speaker cables and interconnects.
For my 1.5 Gb/s Ethernet connection to my DAC/Streamer I use CAT 8, braided (for flexibility/durability) ethernet cable with gold plated ends. $15 CDN for 3m.
Understand the difference regarding different types of signal/data transmission through cables and make an informed decision.
Digital is a clipped analog waveform. Changing from one to zero and vice versa is not instantaneous. There will always be a week link but the critical element is the processing at either end of the cable.
And understand that it is possible for cables to carry more than the intended signal, and that, for example, with at least some DACs RF getting in such as by being superimposed on the digital datastream, though not in any way altering the digital data, may modulate and thus change the resultant analogue audio signal, which may of may nog be subtle. And also, whilst not true to the original recording and undesirable to some people, others might prefer the modified output so produced…
