I have a pair of the Mentor 6 floor standers and the Ikon Vokal center channel. When I heard the Zensors, I felt like ok they were Dali's but didn't have that sonic signature that the others had. This is by no means a properly controlled comparison - just based on what I heard in the showroom when my friend was quickly auditioning them. Could be a number of factors but I chalked it up to the lack of the hybrid tweeter.
I really dig the Mentor and Ikon line but personally would pass on the Zensors. So I suppose my comment wasn't really evaluating the Zensor on its own - simply noting that it wasn't as nice as the more expensive offerings that Dali has. Now I feel dumb. =)
I guess my point is that you don't want to immediately start pining for the nicer model or feel like you're missing out on a signature feature simply to get in the door with a brand at a certain price point. The Zensors give me that feeling. The Mentors do not. Call it insecurity, buyer's remorse, or being hard to please, but I'm not immune to that sort of thinking.
With regards to the Stereophile review...I suppose it's nice to see measurements but most hifi reviews print some variation on the item sounding better than its price point. They do compare the Zensor 1 to the Wharfedale 10.1, which is a lovely speaker and I bought a pair for for my sister.
