Cables For Unison Research S6 and Triangle


Can you advise what speaker cables would be a good/great match for my Friends brandnew Unison Research S6 integrated amp and his Triangle Zays loudspeakers?
My experience
Western electric wire, very natural, good tonal balance, perhaps no as analytical as others
Nordost Blue Heaven, good resolution, but feel a bit bright comparatively.
Transparent Musicwave Plus, very good control, but should like machine, not natural enough

my experience so far, I used to use UR S6 with ProAc T2000s
Discovery Signature.
