Classe Cap-151, Drug on the market?

Not at all, excellent unit. Take advantage of the glut and enjoy one.

I sold mine last year because I was downsizing my system due to a move that would result in a much smaller listening room. I was very sad to let it go and I'd buy another in a heartbeat if my situation allowed for it.
It gets fairly good reviews and is reasonably priced so it has been pretty popular and that is probably why you're seeing more of them. The more there are the more often they are bought and sold. Also, you always see more of something once you start looking for it.
Buy a good one from a reputable seller and you won't be disappointed and you won't lose much (if any) money if you do end up being disappointed and decide to sell it.
