Quad L22 or Castle Cornway to replace B&W N805

Hi,

I own a pair of B&W Nautilus 805 and I think to replace them because sometimes they sound a little bit too bright for me. What do you think about the Quad L22 or the Cornway 3 Castle speaker? What will the difference between this 3 speakers? What I will add? What I will lose?

Sorry for my english
