When using an HDMI cable to connect to a DAC via I2S, what ‘versions’ of the HDMI spec are required.
Old cables were HDMi v1.4, then v2 (4k/18Gbps) and more lately v2.1 (8k/48Gbps).
These specs are of course for video HDMI rather than I2S.
So what level/version is necessary for I2S connection?
Is even 18Gbps an overkill, or is it better to get a newer 48 Gbps cable - maybe not just for the speed, but for example better built, better materials etc than previous types.
Top reviewed cables are not in my budget, so wondering if a ‘better’ old cable rather than a ‘lesser’ but newer type would give the best value for money
