SPDIF Coax cable recommendation?

Hello, 

I'm looking for a recommendation for a coax spdif digital cable.

It will be feeding a Border Patrol SE-i DAC ...either directly from an Ifi Zen Stream (for now) ...or from a Denefrips Iris DDC.

The rest of the system is warm.

Ifi Zen Stream > Denefrips Iris > Border Patrol Dac OR Denefrips Ares ii Dac  > Van Alstine RB10 tube preamp > Van Alstine SET 120 power amp OR Oliver Says 2a3 SET power amp > Fritz Carbon 7 SE mkII loudspeakers

Specifically looking for a rather short cable if possible .  The stream is very close to the DAC...so a somewhat flexible cable would be good.

Also, in keeping with the high value components of the system, I'm not looking for a very expensive or exotic cable.

Thank you

JS
