Sensaphonics does indeed do both the NAMM shows (winter: Anaheim, summer: Nashville) and has a booth set up for the average joe to try them on. The problem I found wth this when I checked them out (I was helped by a friend of the company -- not an actual employee) was that I was forced to listen to their music. I asked for rock and got something that would have been at home in a Vegas elevator. I really liked the sound of the phones, but was the music was so distateful I could say that I loved them.
For those that want to hear them and are *seriously* willing to shell out the $$$, they should contact Sensaphonics and get a recommendation on an audiologist and see if a universal-fit pair could be sent to them. Otherwise, if you like to sweat, they'll be there at Nashville NAMM in July.
From my limited listening, I can tell you that the clarity and detail was much closer to the Etys. There was an eveness, a true flat line, that allowed everything to shine. Even with the horrid tunes, I could hear breath in the music. What I couldn't hear, alas, was the bass -- and that had more to do with the musical selection than anything else. Since lindrone likes the bass, I know I am now doomed this July.
Sigh.
