The manufacturers tend to screw their specs up less than resellers. I'm the first review listed on Amazon, so you already know I love my L880s. I also love my LC2, 2 L8400Ps, and pair of L830s. The sound is phenomenal, the accuracy and lack of coloration is great. The price is outstanding for the product you get. Do I lust after a pair of L890s up front and moving the L880s to the surrounds? Yes. Do I lust after Revel Ultima Salon2s? Yes. Do I lust after a Performance Series system? Yes. Do I lust after anything else near the price range of the JBL Studio L series? Not a whit.
Give them ample juice, good interconnects, and a quality environment to work with and you'll be hard pressed to find anything comparable in the price range. Check out the Stereophile review if you have lingering doubts.
