I’ve just read your LiteOn 52x test : congratulations !
My question is : why do you think cds 200 is quite common while cds 100 isn’t ? There’s probably a compatibility issue.
Another thing : you noticed a low DAE with EAC secure mode. Something likely happens to me sometimes with EAC or Plextools : first track is extracted at 4x and following tracks at full speed. I don’t know why.
It also seems to me that LiteOn team is focusing on audio protections rather than data protections.
