How do the Magnepan 1.7's sound

Anybody hear these at CES and can comment on the sound quality?
They sound like 1.6's. good. Anyone saying it was a standout demo is misleading and kissing butt.
Butt kidding in high end audio! Huhm, I mean butt kissing, does that really go on?
Thanks for the link, James63. I imagine just putting the regular 1.6s into an aluminum frame would give an improvement in sound. I used to own 1.6s five or six years ago and would be very interested in hearing the 1.7s.
