This is new to me. Never heard of CDP to match one's speakers. Any plannar, electrostatic, ribbons will require some real juice to get their optimum SQ as most others have said. If you like the Adcom sound, step up to 200WPC. I would look at the Bryston sst line and a SS pre or tube pre . Frankly, the Adcom is kind of "RAW" sounding to me the Bryston sst line is more refined and better build. Not to mean bashing the Adcom since they made one of the hell good 200W amp back in the 80s ( do not remmeber the model). Please do not latterly side step to another B &K, Rotel, Parasound since you will want to upgrade later.
