Advice neede on speaker upgrade

[stevo67]

Hi
Want to upgrade my speakers thinking of doing front and centre first of all.
Thinking of :-
B&W 600 range dm603s3,lcr60 s3
Kef Q series Q5,Q9c or perhaps the new Qcompact series
or any other speakers that of good quality about this price range
they will be driven by a HK4500 the room size is14"9x11"9
Would like to know your opinions on these dpeakers and if it is possible to run them off my amp.Would spend more on speakers(like dm604) if it was needed or my amp could handle them
thanx guys

Demo JMLab's new Chorus S line. Price range of the B&W 600's. Everybody has their favorites and all are good, just listen if you can...
