Just saw this thread, and wanted to contribute some definite solutions…
First, I must say from the outset that this is the best sounding CD "player" I’ve ever had (and that includes some serious devices like the Naim CDS3 and Micromega T-Drive/T-DAC in the 90’s).
But there are issues :
1) Can’t read a great number of discs (especially CDr). Defective clamp?
This was really frustrating, as I own a lot of these. The puck just doesn’t sit properly on the CD, Meaning that there maybe a variation in the thickness of the discs.
A fixed this by adding 3 layers of self adhesive tape at the bottom of the puck. Thickness may vary, but it now works with 100% of discs.
This is temporary solution, but it’s fine until I tidy it up :-)
2) Screen Flashing
This was corrected with a firmware update that can only be done by a trained technician. Pity the upgrade didn’t replace the terrible clip art graphics :-/
3) Top lid is difficult to handle.
You really need a 3rd hand, when you are trying to place the disc.
This was fixed by attaching a very light self-adhesive rubber piece on one side. It is now easy to raise the lid with one finger..
