Would pair nicely w/ a Zoom ...

Since it plays, and has what looks to be a nice sturdy direct-drive type system (like Technics 1200's, for example, which are DC'd ... booo!), you could duplicate wax ... that alone, is cool as hell ...
The killer add-on would be the reader + image-file format for archival and reproduction. 3D printers spring to life when you add a 3D scanner.
The question is whether there would be more or less distortion and/or "loss" otherswise from reading the grooving w/ a laser or whatever, versus to AD/DA conversions ...
I'm inclined to believe you would get a more accurate reproduction of the original article if you recorded the contour of the physical medium and then cut a new blank to it, as laser/light is REALLY well controlled and very accurate.
AD/DA conversion is probably somewhat of a programming/hardware marvel, but it's probably still just a shit abstraction for reproduction comparatively ...
That's my hypothesis on the thing, anyways ...
I bet they create a scanner to go w/ it, for reproduction, and then it's gold ... I'd *LOVE* to be able to make copies of some of my friends jazz collection, and they'd *LOVE* to know they were making an archival copy with as good an original plate as possible ... having your wax image stored for eternity - game changing ...
Pretty cool device.
