Since no one has mentioned this, I figured I'd toss it out and read the responses.
Looking back a few years at a Stereophile review of the Thiel CS6 (March 1998), Stereophile reports problems with its first pair of speakers, confirmed by Jim Thiel. Does Thiel go to every buyer's house to personally ensure that the speakers are right? Knowing he doesn't -- and that defective speakers get shipped -- should be enough to scare potential buyers away.
Furthermore, Stereophile reports problems with the midrange, saying it lacked "ultimate clarity or cleanness." John Atkinson also wrote, "There was a feeling of reticence in this region, described by one visitor as a 'hooded' quality, that I couldn't eliminate no
matter how much I fooled around with placement."
So while there were major problems with the midrange (of the replacement pair of speakers), the most important portion of a speaker's response, Stereophile highly recommend the nearly $8,000 Thiel CS6. That should tell readers all they need to know about the integrity of Stereophile.
If you want a phase and time coherent speaker, buy either a Vandersteen or, better yet, a Dunlavy. You'll save a lot of money and get a better speaker.
