Zu audio

I am interested in these speakers but a little skeptical of their claims on website

Then why not buy a pair and take advantage of their 60 day trial period to reconcile your interest with your skepticism?

The nano stuff is just the cone doping they use.  Lots of companies do it.  Trenner & Friedl use balsamic oil.  Zu uses some nano material.  

As a Zu owner, I'd say I think about nanotech when I listen maybe once a millenium.

@teleworm,
My experience mirrors yours.

To me, the most important characteristic of the Zu sound is its fullness. Not too bright, not too warm, not too detailed, but full and alive with little fatigue. My Def4s occupy the long wall of my living room that is 22x15x16, and the living room is one end of a 45x22x16 volume. They do not get lost. 

Any Zu owners listened to Wharfedale, KEF or Rega speakers to compare?
