Its upto you, you should hear them and make up your own mind. I would try the Kef LS50s as well.
Which PMCs do you have in mind? I don't you pick a man. that is too general as speakers within the brand can vary quite a bit. I did not like the PMC DB1s much preferred the Kef LS50s but everyone will have different opinions.
What is your budget, music and room size, do you want standmounts or floorstanders?
