I agree with Shadorne on the ATC Actives. Very convincing in their reproduction, and because they are active, you can buy a minimal amount of gear to support them. I prefer Bryston solid state pre-amps with them and you could keep or enhance your source components.
If you wish to migrate to a warmer, tube sound: Two other tube systems that sound great are top-of-line Opera speakers with Unico Research tube components, or the new Harbeth 40.1 speakers with a good Japanese tube company (audition Leben, Shindo or Almarro.)
