Hidden Gems in Pre-Owned Solid State Power Amplifiers?

hopefully we find that one man's seller's remorse = another man's great deal and not always just a washed up, flawed hand me down.  
i find that it takes work to get the best out of new pieces in your system, new or used.  
although there are many repeat offenders that wind up on the used market often there are also many items being sold that I own or have owned and understand their value.  
in the end there are many audiophiles that just like to move on regardless.  

Any love for the Cary solid state power amps? 
They come up regularly but don't seem to be a dime a dozen like many others....
