New vs uses in your current setup

mine is pretty much 80/20 (New, used)

New and well on it's way to being used.

Probably 50/50 for me. When I was younger, I almost always bought new. Now, most of my 'new' gear is demo which has saved me a ton of money. I may not ever buy new again. 

In my system, the speakers and amps are new, everything else has been used.

I do both.  I replaced a new amp with a pair of used ARC monoblocks, and I replaced those with a new Cary that I am still running.  I replaced a new pre with a used Cary, and I replaced that with another used Cary.  I replaced a three piece digital front end that I put together with new pieces with a Marantz that was a "factory refurb" (so I guess that counts as used).  So far my speakers have all been new, but I would consider used on those as well.
