Thanks to all the responses. The reason I'm thinking of swapping out my Marantz SR 7000 is because Dr. Hsu (of Hsu Research) recommend an Onkyo receiver as a good match for the VTF-2 sub. I'm looking for a receiver that matches up well with the Axioms and the Hsu. Currently I'm looking at the HK AVR7200 or 630 or the Onkyo TX SR800. I've heard good things about both the HK and Onkyo speakers with the edge going to the Onkyo. I'm planning on putting the Marantz downstairs and matching it up with the Energy surronds. Any thoughts on the receivers listed above?
