Streamer to Denafrips Iris to Pontus need cable suggestions please

I’ve got a Iris on the way to mate to a Pontus and have no idea of the type or brand or the quality/price cable I will need. It’s coming from Auralic g2 which has usb, coax, aes,  tos, lan. L-link. 
 

What type and brand/ model do I go from Auralic to Iris. Then what type cable and then brand/ model do I use fro Auralic to Pontus.

There will be a HiDiamond RCA’s going from Pontus to Audio Hungary a50i. Audience au24 se and TG Audio speaker cables going to Joseph audio Pulsar and Reference 3a towers. 
 

I know this is a lot to ask but I am not familiar with digital cables. Only digital cable I ever owned is a spdif. I’m using a JPS Labs superconductor true digital coax from streamer to Pontus now. Can I get away without spending a lot of money since some say it’s just digital, probably not, sure hope so.
