I second Duke's Shahinian recomendation. Listening to them is very much like listening to live music. If your on the left side of the room, it sounds like your on the left side of the stage. Moving forward and back sounds like approaching or retreating from the stage. There is no focused sweetspot outside of which the listening enjoyment diminishes. You're just hearing the musicians from different locations in the room. And if you like bass, you'll love the Shahinians.
