I presume this is the original version. Yes, there is a very small improvement that I heard on many CDs, but not on CD-Rs probably because the material that the data is written on is organic not metallic. This is an inexpensive toy to experiment with but can lead to OCD behavior in place of music listening. The box is 7 x 6 x 9, weighing 5 pounds, but plan on 7 pounds after padding and a larger box for shipping. From ZIP 18661. Asking $35.00. See one photo in the Gallery.
