I invite people to share their experiences and/or opinions about purchasing speakers used. This is my experience. I had a cheap HTB system for a couple years, and caught the upgrade/hobbyist bug a couple months ago. After auditioning numerous speakers, I opted for Paradigm. I was significantly more impressed with the Reference line, but could only afford the Monitor line. However, my local Paradigm dealer had a Christmas clearance sale and the Studio CC (demo model) was on sale for $350. So I picked it up and figured I would get Reference line mains when I could afford them. Well I ended up buying used, as you can tell from the topic header. I decided to pick up a pair of Studio 20 v.2's from a hobbyist on Audiogon, $400, black laminate, six months old. In addition, I grabbed a pair of Titan v.2's for rears, also six months old, $145, including the MB60 wall mount brackets which I needed (the brackets are I think $40 retail). The Titans arrived first. They were packed not in their original Paradigm boxes, but very professionally, and included the manual that came with them. The speakers were in pristine condition, literally indistinguisable from new. The brackets came in their original package resealed with the screws. I have not mounted the Titans yet, but I have tested them and they are thoroughly broken in. They sound beautiful. The Studio 20's came in their original Paradigm boxes, also packed very professionally. Like the Titans, the 20's were indistinguishable from new. Not a nick or a scratch. They too were totally broken in and sounded wonderful out of the box. I also picked up the Sony WM40 sub new for $135 online. And I got a Denon 3801 demo model off ebay for $475 +$25 shipping +$20 for an extended warranty from vikingwarranties. In all, I am extremely happy with the fruits of my upgrade fever. Although I do not have the Titans set up yet and still have the cheap rears, the system is already 1000% superior to my previous setup and easily worth the $1500 spent. I think buying used is extremely viable in that it allows you to buy a level of quality beyond your price range and has the added benefit of bypassing that often lengthy burn in time associated with new speakers. However, those who are conservative and risk averse obviously will steer clear of this route. It also may be that I got lucky with the quality of the speakers, so my experience may be atypical. I do think that when you buy from sellers at places like audiogon or the forums you are typically buying from hobbyists who tend to pamper their equipment. BTW, I want to thank everyone here who helped me out with advice on my buying decisions!
