Good observations Ltleo.
I did listen to the Wilson Sophias 2.0 and B&W Signature Diamond which have two very different sounds. With that experience, I still prefer the Dali 300 with my current system. The Signature Diamond tweeter though has killer imaging and outstanding details. Sophias which is my third time listening, still is not my cup of tea.
Hopefully I can listen to the mk2 soon.
