Hi, I have a few weeks on my Maxx 2's now. They are clearly a better speaker in every area. The are still wilson's, and the WP's are still great. The Maxx 2's just present more information, everywhere. More dynamic, more revealing, bigger wider deeper stage. More delicate, yet more powerful.
Since you're here in Austin (sorry I missed that the first time), and we likely have the same dealer, stop by and listen to mine. I think the Maxx2's take less treatment than the WP 8's . Just less to correct, however if you're using Ne Plus Ultra in Austin, they are experts at dailing these in. Either will sound great. I have ASC Corner Tower Traps and just 4 ASC Wall boards (don't know the exact name-you can see em in my system pics).
Good luck !
