I know this is an old thread, but I was just poking around looking for amp recommendations for Piegas and happened upon this and I almost spewed Dr. Pepper out my nose when I read this:
"B&W Matrix 803 series II speakers walked all over them"
I've owned C3 Limiteds longer than any other pair of speakers I have ever owned. The high frequencies and midrange is the most beautiful I have ever heard. The bass is superbly tight and musical and is nowhere near as bloated as B&W or most other speakers for that matter.
That said, these speakers are not "plug and play". They will require careful placement to sound their best and they will reflect ANY changes in the upstream. I have heard these with $24,000 amplifiers, and still have been unable to find the limits of what they will do when fed the right gear.
I can't recommend C3 Limiteds highly enough. Nothing for the money will touch them if you like a neutral speaker that is supremely revealing and shines a beautiful light on the highs and mids that's truly addictive.
