How many people here generally buy used?

Eh, kinda 1/2 & 1/2, but I like trading gear too. 

Mostly used about 80% except for tonearms and cartridges those I always buy new.

"How many people here generally buy used?"

Only two items were purchased new. Oddly both of them preamplifiers. A Yamaha CX-2 and recently a BHK. 21 years apart in time. Maybe that provides enough time for one new purchase?

TT, phono preamp, speaker cables, interconnects, power cords all new. Amp, CD transport, DAC, receiver, speakers, subwoofers all used. Why? Don't know. That is how it played out. It was time to make a move and that is where I ended up. Could have played out different if the circumstances at that time dictated otherwise.  So I guess 50-50 but not wed to that model. Very easily could have been 75-25 or 25-75.  Just depends on timing. 

I've bought mostly new but I've also purchased demo and open box. I've gotten some great discounts on demo models.
