B&W, Dynaudio, Dali or what else?

I currently own a pair of Dali Helicon 800's but want to upgrade to the next level. In other words I am looking at Dali MS 5's, Dynaudio C2/C4 or B&W 802D's. Any opinion on either speaker would be welcome as well as recommendations for other well designed speakers. Amplification is ARC LS25/or SF Line2 SE and VT100MkII. Please no one liners with statements such as, buy the XY model from company ABC they are just the best. I'd like a little bit more detail for the money I am about to spend.

Regards

Mike
