B&W N800 vs Wilson WP7 vs Revel and others

I plan to upgrade my N802's in the near future and have a few speakers on my short list. I an interested in hearing everyone's thoughts or opinions. My short list includes:

B&W Signature N800's
Wilson WP 7
Wilson WP 6
Wilson Sophia
Revel Studios and Salons
JM Labs Utopia
Sonus Faber Amati

My current system includes Krell FPB 350 mono's and 7.1 processor. I will be using the latest EMC 1 cdp. Thanks
