B&W N800 vs Wilson WP7 vs Revel and others

Well, YOU better check again. Focal is only the tweeter. And nothing wrong with them either. Scan-Speak 8545 is widely used mid/woofer. Seas Excel is another "cheesy" off the shelf driver that was succesfuly utilized by Joseph's (20K) Pearl. Quality of the Individual parts doesn't mean much, but the sum of the whole. 'Till recently Dynaudio drivers were also available off-shelf to DIY-ers. That didn't mean that they were "cheesy". If you want "cheesy", try opening-up your Dynaudio Countour 3.3, and take a look at the $20 crossover parts!
Also, i do not believe (ANY) speakers should cost $20K either!

Not true! Scan-Speak drivers used in Wilson midrange is one of the best, if not the best midrange you can find regardless of the origin (off-shelf, or house made). Wilsons, just like any and every other speakers have its issues. He went and at least listened them for himself.
Although, would like to hear them against Joseph's Pearl.

I guess, we agree more than the initial posts would suggest. I own Dynaudio 3.0, and after the x-over upgrade took the sound to the new level. Bennic mylar and Solen caps were replaced with Mundrof and Hovland. Very disapointing finding that relatively expensive speakers would use very cheap parts. My friend did the same with his 3.3. I would hate to be owner of the >$20K, and find less than premier parts in any way!
