Four of the last six were bought without hearing them. One was returned (Walsh Ohm Tall). For the other three I read or watched every review and looked at user comments in the forums about the speakers/manufacturer. Two of the three (Volti and Coherent Audio) had something similar I could listen to (Klipsch/Tannoy) so those were not completely blind. The third was Tekton which was completely unique. Those three also had some type of custom finish which was important to me as well.
My next pair will probably be direct since it I am looking at open baffle - PAP or Caladan?
Good luck.
