I would recommend getting the Onkyo. Not only will it decode DTS-HDMA whenever you get a capable player, but Onkyo receivers in general are cleaner sounding than Pioneer receivers (even Elite models). If you are hard pressed in a specific amount of power, get the Onkyo 705 (3 HDMI inputs, 110 WPC, and THX processing).

The Onkyo 605 also uses the Audyssey automatic setup which measures 3 separate listening points in the room, not just one, to create a balanced sweetspot for all listeners. The 705 and 805 have the ability to measure 9 listening positions.

I think you will be blown away by the sound quality that Onkyo is able to achieve at their price points.
