B&W N800 vs Wilson WP7 vs Revel and others

Your list looks alot like mine a year ago. At this level, the list doesn't get too long anyways but you should not confuse B&W and Revel with Wilson,JM Lab and Sonus Faber. The latter being levels better in sonics and build quality. No list is complete without Merlin, Aerial and AudioPhysics at this level either. With your amps in mind, I would lean twards Wilson or Aerial. I don't mean to slam B&w or Revel but marketing is one thing and head to head comparisons is another.

You didn't mention your musical tastes which might well influence matters or if price is an issue, all important considerations. I have heard some but not all the speakers on your list so I am cautious to say anything negative. Another line to consider, especially with krell would be the piega. A friend looked and listened to the b& w and went with the p8ltd, the new c series limited are substantially better IMO. The other speakers are well known and excellent but I think you might do well to try and audition. Good luck

Better ad Avalon Eidolon to that list or you will end up getting the wrong speaker. The Diamonds if you have got the scratch.
