New vs uses in your current setup

My system is 50/50 new/used.  The more expensive pieces are the used ones.

About 60% used , 40% new.

Prefer used just for the cost to level of performance. Occasionally the right SUPER sale will get my attention and money.

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.
