Well I am going to play the Devil's advocate here because I have owned WP5.1,WP6, Maxx l's, X-1 Series lll and now X-2.
They are all terrific speakers BUT my recommendation to get the best bang for your buck is NOT to buy any of those used but rather buy a NEW pair of Sophias. For the money and with the correct gear they kick ass. They are absolutely wonderful. My advice is to audition them and find a dealer with a reasonable price and you will thank me.
here are my X-2's
