$1500 for 1 used cable? You can buy pretty much any Transparent Ref cable you want (my favorite)...but you could also get Valhalla, Argento, Jorma Prime, Kondo, PAD Dominus.
Are you saying its $1500 per cable, so roughly $4.5K-$6K to cable the entire system or so? Or $1500 for all cables in the system?
