Bought a VS110 new 5 years ago, it's a beautiful amp for $2,700 used. Had numerous opportunities to trade up to a Ref 110 and haven't done it so far, actually I no longer have interest in changing it. Changed to KT120 which brought it up a notch I think (6550 had more than 1,500 hrs, the difference was very noticeable). With the money saved you can buy yourself a Ref 3. These two can sing together.
