I would like a all copper wire.
I’m gonna challenge you on this. I’ve got Arya Stealths and am using a LavriCable silver balanced cable and think it’s sublime. I think a copper cable would blunt its inherent air and detail, and in no way is my sound bright or harsh. If you like lush and warm by all means go with a copper cable, but if you want neutral and natural sound I’d highly recommend LavriCable that are a huge value in pure, silver cables. I got their 1.2m Ultimate cable with their top AECO connectors for around $250 and think they hit the sound straight down the fairway with nothing to criticize. Many other users here have been extremely happy with Lavricables too. Just my $0.02 FWIW.
