How many people here generally buy used?

I just made my first used purchase, a First Watt F7 amp.  Shortly afterwards I purchased a used McIntosh MCT450 transport.  

To me it makes more sense financially to buy higher end components used. 

Generally used. Downside of used is selection, so one needs to be patient. I believe most audiophiles take very good to excellent care of their equipment so buying used isn’t quite the crap shoot as much car might be. Like others, I look for the good deals, new or used. Most of my current gear is used or demo.

Around 80% of my gear are used because many are older than me. I am into good, old stuff. I have integrated amps/receivers from the 50's to 70's. My main system has KEF speakers from the late 70's and c-j electronics from circa 2000's. My most recent brand new purchases were a tonearm and a cartridge, a pair of monitor speakers and a secondary phono stage. Even my latest DAC was bought used. As many have mentioned, it is important to learn how to buy used.

I buy used. Buying 40 year old equipment is hard to find new in a box. I buy low enough $ wise to justify having it restored, recapped ect. Speakers I generally restore myself, in and out. I like bringing old gear back to its original glory then passing it on for someone else to enjoy. Sometimes I even make enough to justify the hobby. Definitely not a get rich program. 

Mostly used — here’s my setup:
Speakers - used (Usher)
Power amp: used, then factory refurbished (McCormack)
Pre: new, but not high-end (Parasound)
DAC: used (Benchmark)
TT: used (Technics)
Cart: new (Nagaoka)
Streamer: refurbished (Bluesound)
CD Player: used (Cambridge)

I’ve been very happy with all my used purchases, and would have had a hard time getting into this hobby without them!  Good luck.
