i Have two pair if Coincident IC.I bought fro Arthur At High End Audio.They are the best i have heard.I tried all the big guys Nordst,Jps,Audioquest,Wireworld,Ixos,Cardas,Tara Labs,Alpha Core,You are not going to get a better cable without spending 5/10 times the amount and there are many out there at 5/10 times the cost that are no better.The speaker cable is the same.Its huge value for the $ spent.
