KEF and ProAc

I have a pair of KEF 102s. These are the third pair I have owned and I really like them (as well as the 103.2s)This summer I am thinking of purchasing a pair of floor standing ProAc speakers. My question is. Does anyone have first hand experience comparing these two types of speakers? They are both British and highly thought of. I am looking for more bass and favor "musical" over "revealing". Is it possible that I would be spending significantly more for the ProAcs without gaining much in sound quality.
