Thiel CS1.2 vs. Ohm Walsh 2

I'm not really an audiophile, though I do love to listen to music.   I am looking at a pair of Thiel CS1.2 speakers, vs. Ohm Walsh 2, for about the same price.  Both in decent, not perfect condition, Ohm needs grills which would be an additional cost.  No way to listen side by side.  Listening to B&W 685 speaker with Polk 10" subwoofer driven by a Denon 80 watt/ch AV receiver (Denon AVRX100w).  Room is 20' x 15' x 7 or 8' ceiling.  Listen to primarily "classic rock" and some jazz. Any suggestions oh gurus?
