Wish try it once. I have two cable stock fir includes SPC and Pure Cooper. I also tried the 1960s 4 wire with my M5 that's an excellent pair but i have to use an adapter which i just use for test cable which I never like to use for a long period of time
I happen to have 1960 2wire (stock from Odin). Is it good enough for M5 as well?
Sounds like a 4 wire silver cable would be a good alternative to the M5 stock+copper and 1960 cables...
