Perhaps 10% new gear, the rest used, some of which I have owned for decades. I occasionally swap units out from one to another of the three systems I run. Once in a long while I'll go looking for a new item to try.

Curious the ratio new to used/demo in your current system comprised of.
I’m equally split on a “per box” basis although I tend to look for used cables almost exclusively.
