It's interesting you should say that, because I've always thought Sim had a house sound more on the warm side, and the Moon systems I've heard always impressed me as having a full midrange and detailed highs. As for the W3, I thought some more power might yeild better, more controlled bass. The Focus 2020 have 3 12" woofers each, and although they are highly efficient thats still alot of cone to move.(maybe I'm wrong in that conclusion, but the experimentation is half the fun). 95db sensitivity, 4 ohms ,10-600wpc leaves a huge window of choices, and I'm not locked on any particular amp, but the source is next on my to do list
