Active VS Passive speakers and, specifically, Elac Navis ARB51 as the active speaker?

We are moving into a new home this Fall and I want good sound for music, TV and voice (podcasts) at the $2.000 to $3,000 price level.  I am new to the quality-audio arena and would appreciate some advice.  Should I go with Sonos Fives instead of the ARB51?  Is the KEF LS50 a better choice.  A solid recommendation for a newbie would be much appreciated.
