This is not quite new. I sent them a cartridge with about 20 hours on it and they did the mod. I'm telling you this because you would not know otherwise. It may not even be broken in. Original packaging included.
You can read about this mod on the Zu website.
http://www.zuaudio.blogspot.com/It is creating quite a stir among reviewers, several of whom are evaluating it right now. Zu sells this for $400. I will sell this one for $300.
My reason for selling without listening: It is too heavy for my arm.
