Well the biggest I've seen were Kimber cables don't remember the model # but they looked quite similar to a Blue Indigo smake in both markings and diameter. Cost 8-10k I believe for an 8' pair. How did they sound you ask? Well I listened to them on an unfamiliar system, big Montana KAS speakers and a Cary push pull 100 watt tube amp. The Cary was most definitely the weakest link that is for sure. But I am not a big Cary fan other than their SET's which I suspect aren't the best. My 15 year old ARC was much more neutral than the Cary which was much too euphonic.
Biggest Baddest Audio Cables
Whether they actually sound better or not, I don't really care but I have a fetish for beautifully made, anaconda sized audio cables, especially with unusually well made connectors. Any ideas here especially where 2nd hand is a deep discount would be greatly appreciated. Thank you.
