Well we finally have a decision.
I undertook a 2nd listening test for:-
Monitor Audio RS6
Monitor Audio RS8
The Keff''s are an attractive speaker, and delivered a beautiful clean clear sound, but again it didnt deliver a 'Big' sound that I like with a bit more bass to it.
Monitor Audio RS6 - Very disappointing in that it was no where near as good as the BX6 in performance for me.
Monitor Audio RS8 - A bigger sound with the extra bass weight, but lost it in the mid range.
So it was an easy victory for the Dali Ikon 6, and I would place the Monitor Audio BX6 in 2nd place.
I also managed to barter a very good price at Richer Sounds for the Dali £775. So I am really happy.
