New vs uses in your current setup

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.

25% used. But I don't buy cables used anymore at least not AQ or Nordost. Too many Chinese knockoffs on the used market. 

For years, it was always nothing but used gear, but as I look at my system across the room, surprisingly, it is 3/8 pieces are new.  A Schitt Mani, Bluesound Node 2i, and an Audiolab 6000CDT we’re all purchased new.

This thread made me realize that I currently don’t have any used equipment in any of my systems.  I had a 5 channel Parasound power amp in one of my HT systems, approximately 30 years old and in my possession for the last decade or so, give up the ghost 2 months ago.  I have had many previously owned through the years but I haven’t been buying or selling components for a few years, finding it was a lot more hassle than it was worth, with scammers,etc.  

I'm in a Trigger's Broom (Ship of Theseus Paradox) situation, if you bought it new in 1986 and refurbed it three times can it still be considered original/new?

If so I'm at a new/demo/used ratio of 40/20/40.
