I’ve heard others say they don’t hear big differences between HDMI cables in an i2S application so maybe that has something to do with it. Thinking I’ll try a DH Labs HDMI at some point, but given what I’m hearing now I’m in no rush.
I will have to admit that my statements on i2s are all based on hearsay. I have not done any testing with i2s because of the restriction on cable length (it would not work in my scenario). That being said, based on my experience with S/PDIF, I would guess that larger awg solid core conductors would work better and if you can get solid-core pure silver that would perform even better as well.
I see that Wire World has released a new version of their Platinum 8 HDMI cable. This may be the best result you can get for i2s (but I'm only guessing). At $800 for a 0.6 meter, it is definitely expensive, but not the most expensive cable. I have seen previous versions of the Platinum 7 HDMI cable up for sale, but those are extremely rare.
Using solid core pure silver for S/PDIF (and i2s I would guess) is extremely revealing. This means that a pure silver cable -could- sound worse and make your system too bright because it now reveals flaws in other areas of the system (such as other analog cables, or switching power supplies, or certain capacitors that manufactures use, etc.). But in my audio system, an 18awg solid-core OCC silver AES/EBU digital cable presented the absolute best results (after testing around 6 different wire/connector configurations).
