Are Cardas Parsec cables Overkill for Zen Stream?

Total newbie to better-grade cables here.  I’m wanting to put an Ifi Zen Stream plus Zen One Signature DAC into a workspace system built around a NAD 316 BEE V2 going into Klipsch RP 600M speakers and (eventually) an REL “T” series sub.  The Cardas Parsec half meter SPDIF and RCA interconnects have caught my eye, are within my budget, and seem to lend some taming of sibillants/forwardness based on available ‘net opinions.  Would these be overkill for this system?  Any issues of synergy or lack thereof with this setup that jump out to folks with more knowledge in this area than I?

Thanks!
