Why Are There So Many Audio Research Reference 5SE's For Sale

I wonder if the Ref6 is on par with the Ref40 ?

Thanks all very helpful but no one has really described the sound to me..how does it outline images in three dimensional space...are the outlines really sharp with the right sense of scale? what about its tonality? stage depth and width, mid-range, female voices,? I've always considered AR as close to solid state as you can get from tube gear..but then again, Ive never owned only heard it at a show or a dealer..

I've never owned AR before,always was very much impressed with their sound at the store.So broke down and bought reference 210's and have just bought ref.5se.here in a week.Anyone have this trio,and will I be a happy camper.Hope so,looks like ramen noodles for about a month,sure hope they're worth it.I was getting fat anyway.

I am a big fan of ARC gear. A number of years ago I owned an LS26 and was in the market to upgrade to a REF 5 when I came across a deal on a 40th Anniversary.  I chose to make the investment. I decided that for a few thousand dollars more I could buy the piece that I would build my system around and not get on the upgrade train that David alluded to. I couldn't be more pleased with my decision. As for describing the sound- that's tricky!  I have upgraded my system around it and it has yet to be "exposed". The better the gear around it the more incredible I realize that this piece is. All I can say is my system (available to view in virtual systems) is far beyond what I ever expected that I would own. It is natural. It is amazingly three-dimensional. It is tall. It is wide. It is deep and layered. It makes me happy. The key word in that last sentence is ME. What I have come to learn is that everyone's definition of perfect is different. For me, right now, my system is close to perfect. I suppose that's all one can ask for. Please keep in mind that a system is just that. I've gotten great advice, done some decent homework and managed to put together pieces that are remarkably synergistic. Some of that is skill and, in my case, some of it is luck. But, I guess as the cliche says, "luck is what happens when preparation meets opportunity!"  Happy listening- and good luck to you!
