Thiel CS 1.6 vs ProAc speakers vs ?

I'm looking for a speaker within the Thiel's price range. My electronics: Jolida JD-100 CDP (recently purchased), Conrad-Johnson PV-12 pre-amp, and Aragon 4004 MKII amp. What I'm seeking to hear in music reproduction: a reasonably neutral, but involving sound, with very good resolution. I listen to old rock and pop, different types of vocal, and classical (mostly sypmphonic) music.

Thanks for your recommendations or advice.
