I knew from being somewhat involved in the interconnect business world that gold to tin was not a reliable connection.
You were addressing soldering to gold contacts, do you know how long it takes for gold to tin connections (not soldered, but cable to component) to de-grade?
The Denon 3805 does not have gold interconnects, but the Denon 5900 does.
I guess a $1200 piece of gear (3805) doesn't qualify for high end. And at $2000 the 5900 (now discontinued) does. So in this case, one end needs to be gold and the other end needs to tin.
