Anybody have info. on an Esoteric CD-Z5000

I know this was built by Teac, and I have seen the Teac D-Z5000. But I actually have an Esoteric CD-Z5000. I've never even heard of anyone else having one of these or seen anything on-line either. Are these rare? I know that when I play it, I've died and gone to heaven. Esoteric definitely know how to make a transport. Smooth as silk and every detail and nuance is there in the presentation. A real eye opener.
