HDMI (i2s) recommendations for Denafrips Gaia -> Terminator

I have a denafrips gaia on the way to use with my Terminator DAC and I'd like to connect it using I2S since I've heard that this is the best sounding method. 

Any recommendations on a good sounding HDMI cable? I'm considering the AQ Firebird 48 which is fairly pricey and is probably the maximum I'd want to spend ($1299 for 0.75m length).
