I2S is concetually good and many swear by it but implementation is sketchy and your example is just one of many.
I'm with Erik on USB. Try both and if you can, and see if you can tell the difference? Unless I2S sounds better then USB should be your go to. Lots more cables availabe.
For digital signals I always like silver plated (or solid silver) cables and Audioquest offers lots of them in any price range.
