Not sure how to put it into words. They sounded very different from one another and I simply preferred the Evo's.

Sure, the Opus towers pounded out the bass; but who needs that if you have a good sub. I actually came close to getting the Opus towers instead of the Evo 30's; but at the time they only had the towers and center channel on closeout....no surrounds. I would have had to buy the surrounds at the normal negotiated price; which probably would have been 15-20% under MSRP. That was another factor.
