This is their response. Does this mean the quality control issues have been fixed and a buyer can have confidence that the problems have been eliminated? I emailed them back and haven't gotten a response yet.
BTW--I picked up a used copy of Miles Davis, Highlights from the Plugged Nickel. Wow!
"Thanks for your message. There have been several improvements over the years. A number of firmware updates that fixed various display issues and power and CD reading issues.
The top lid has received a modification to sound proof the CD player, as the CD Pro 8 was often a bit too noisy, especially when used in small rooms. It was fine with CDs that were very straight and not bent, but some CDs that were in less of a good shape (which are more than one would think) were noisy.
There have also been various improvements to the packaging and securing of the drive for transport.
Best regards,
Dominik Hofer"
