Hi Luvmusic8,
Haven't heard the Omega, but I own the Zu Tone and have heard the Druid. Both have the warm midrange you're looking for in spades. Between the two, it comes down to the amount of bass you're comfortable with (with the Druid obviously giving you more). Eight 300B watts should be more than plenty for either to fill your space.
Let us know which way you go.
Merry Christmas,
Garry
