If you are still in the "deciding" stages take a look at the Onix Rockets. My auditions included the Studio 100s, and Energy C-9s. I thought the Energy were better overall, but very close to the 100s. Then I tried the Rockets. MUCH BETTER (IMHO). I'm no expert by any means, but the soundstage seemed much more forgiving on the Rockets. Individual instruments also seemed much "cleaner"?, on the Rockets. I have the 750s fronts, 200 (I think?, its the BIG one) center, 300 sides, and 550s rear. Also a plus but not a requirement the Rockets LOOK like a million bucks.
