Buying used vs new?


Chance to buy a preamp used at half price.  Its been used for several years.  Seems a good thing. Worth doing?

Just replaced the core of my system after 4 1/2 decades. New used Cary SLP05 with ultimate upgrade and a SST Son of Ampzilla II, both bought at half price and in near-new condition. Good  stuff doesn’t break much, and is fixable if it  does. Best way to get into the top tier gear, in-house. The stuff I replaced ARSP6B I got used at near half price, and a GAS Ampzilla that I built, both still working great, I got my money’s worth!
Depends on the preamp. Which one?  Saving money is good....getting great equipment with your money is better.
Nearly every component in my system, including my preamp, was purchased used, either on here or the other major resale site. The only things that were purchased from a dealer were my speakers but I bought them as demo models, and my turntable, also a demo. Preamp should be absolutely fine as a used purchase. Would probably avoid buying a TT used unless you can pick it up in person. Too many little fiddly moving parts that could get damaged in transit. 
There’s a lot of considerations between new and used purchases, including warranty and availability for gear support if needed. My systems contain a mix of new and used gear. I was able to pick up my VAC preamp for 55% of new retail buying used. It had only been used for 6 months and there was no way I would find anything new to compete with it in the same price level I paid.
