Advice on a good Digital Coax Cable to run between my Transport and DAC?

Don’t mean to hijack thread but I’m confused. Two brands of AES/EBU cables I’ve looked up online (including Jorma) state they are 110 ohm. If 75 ohm is considered "best", then why would Jay’s optimize their transports for AES/EBU? 

I have a CDT2mk3 and want to make sure I’m enabling it to perform at its best. What sort of sonic improvement might I get from shifting to  AES/EBU?

Thanks. I misunderstood; I thought 75 ohm connection was considered superior to 110 ohm.  Now I get it.

I'd be curious to try both versions of a single cable.

Doh!  Just realized my Hegel doesn't have XLR digital inputs so I can't try AES/EDU cables with this set-up., It'll have to wait until I acquire another external DAC.
