Question about amplifiers

Greetings, my first post here. Long time pseudo audiophile. Currently I have 3 pairs of Martin Logan speakers, surrounds, and cinema center. I came across an unbelievable deal for a perfect pair of Kef 105/2. No problems with drivers, rustiness teak cabinets ( wife likes those!!!) and both pairs of dust overs. Listened to them all day Friday and they were as I remembered them. I first heared this speaker back in my college days and couldn’t begin to afford them. 
  My question is, I am currently driving them with a Rotel amp ( 130 wpc). I also have a vintage Adcom gfa 555 (white case, rare, have full set). Local dealer recommended to sell the adcom and buy something newer. I’m not in the really expensive category ( my wife doesn’t understand), and my old ears don’t work like they used to. So, sell and upgrade? Keep and listen to all my assorted speakers? Any recommendations would be appreciated. Thanks.
