While I don't have any experience going from solid state to SET, I can tell you I looked very closely at getting into SET and came to the conclusion that it wasn't worth trading out my speakers (Spendor 1/2e) so I went in a different direction (the speakers I was considering were the Zu Druid at $1800 and an Audio Note Kit at $1900).
Since you appear to understand and accept trading out your speakers I will make a recommendation to you for reserach purposes. In consideration of the fact that you are looking at Dared equipment, you should go to the Decware site and look at what they are offering. Both in terms of speakers, amps, and preamps. Now given that you only listen to CD I will also throw this out there which could save you some money and allow you to throw more dollars at the amp and speakers. You could get a set of attenuators like those made by Endler ($160 new) and EVS (~$200 or so used). These hook up to the inputs on your amp and provide stepped attenuation like any other volume control and it is geared for single source. If you need remote, you could try the Welborne or Space Tech Lab units instead (both these vendors also offer nice SET amps and tube preamps) which will only require the additional cables to implement.
