HDMI cable to utilize I2s Connection from LAIV uddc to Denafrips Terminator 2

Obviously HDMI cable will work, I'd suggest using I2S cable for long term, this especially  if considering higher cost options. In consideration of costly material such as silver why pay for the unneeded runs in HDMI cables, 19 pins vs 8 pins/runs. As for sound quality, haven't directly compared HDMI to I2S. If more costly cables considered I'd suggest Tubulus, I use the Ximius.

.5M or less for cable, this even more important if one is syncing to DDC clock vs dac internal clock.

I'd never use or purchase any I2S capable component without pin configurable switch. Certainly you can have custom I2S cable manufactured, but that cable will be obsolete with the next I2S component, and things continue to move at a relatively fast rate in streaming audio. Inexcusable that any manufacturer still offering product without pin configurable ability.
