Ayre balanced interconnects

Bigtee: thanks you are always very helpfull.

Which one sounds better - Cardas Golden Reference or Ayre Signature Series ?

can´t support your opinion. I use Cardas GR and they sound excellent with my gear (beside I use Acoustic Zen, Shunyata and Stealth Indra).

Ayre uses double gauge of Cardas GR and sounds at least in my system better than Cardas Golden Reference - although I use the GR.
Saying a cable kills another is quite difficult as I´ve experienced quite cheap cables performing superb in one system and failing in another. Same with very expensive cables. The only exceptions I know of is the Stealth Indra, the Transparent Opus, and the taralabs Zero and Omega.
