Proac Future point Five vs Thiel 2.3- Opinions

Pro-ac has been making speakers for nearly 20 years; but, they always seem to be changing their models. A friend wants to sell me a pair of the relatively "new" Pro-ac Point Five speakers which uses a ribbon tweeter. Recently, I heard a pair of Thiel 2.3's, and thought they sounded good, though their soundstaging was average. Need some opinions about these two speakers, especially the new Pro-ac model. ( As a industry reference,I have heard and read good and bad things about the "older" Pro-ac speakers. For example, some claim the Pro-ac 2.5 is outstanding, others feel it sounds muddy compared to the Thiels.... I listen to a lot of classic 60's stuff, including Grateful Dead, Osibisa, Stones, Traffic, but also do the Flim and the BB's and David Benoit stuff( elevator jazz) which is nicely recorded and because the wife thinks its cute music. I have an Aragon 4004Mk2 amp and modified CJ PV-8 tube pre-amp; I also have a Sonographe CD player and VPI table with Sumiko MC. The room is about 15X20 and has a 13 ft ceiling; I tend to play it loud but am not a headbanger. Many thanks to the members!!
