I've added the description to the first post, which mentions "Expertly restored and remastered in superlative audio ... on MQA quality CD". The MQA logo is indeed present on the back of the package:

Is it possible that this inexpensive little CD is actually MQA-encoded? Or are they saying MQA the way other discs say "24-bit remastered", referring strictly to the remastering process while the CD itself only plays in 16-bit?
