Meridian
Genelec, etc. DSP active speakers will be the easiest to position in any room regardless of parameters or components and give consistent performance. Read a few reviews. When you are finally done shopping, touching, drooling, speaking for myself here, and just want to sit and enjoy all the music, not just the songs tuned to your system, go listen to some dsp self powered speakers and then wonder why everybody isn't using them. I'm thinking of having mine chromed and putting some custom power meters on them. No i'm not related to kenjit.
