@vin_eme ... nice timing
I was also thinking in the same way. Do you think the 1-0-1 switches come with OFC connectors? Does it make any difference anyway?
all of the banana sockets and leads are gold plated. The 1-0-1 switch are copper leads. Thats the best i could get. Also since the current is high at the amp outs, i have not seen any switch related contact problems. Almost after a yr of use, i felt some contact problems, but with a simple trick of pressing the switch 10 times clears it. Best option would be to have a Silver relay to do this. That would be best IMHO. But this again calls for a separate PS.
