Those Kef are not the last word in resolution (quite British polite in fact) - so I am surprised you find them harsh and bright.
What are you using to drive them? I would recommend a warm tube preamp (not lush but warm). Mcintosh or Conrad Johnson. This will take the edge off everything and give you some mid range warmth.
What is your room like? Do you have absorbing rug or carpet? You might need to reduce reflectivity.
