A strange one - perhaps?
I bought a used CD from Ebay recently - but when downloaded on iTunes and transferred to Sonos system the audio playback was poor quality.
So I cleaned the disc with Isopropyl alcohol and tried again - same poor sound.
I then acquired a second copy of the same CD from a different seller and repeated the download etc. - same result.
The chances of both discs being iffy must be slim I would have thought ?
When played on my “boom box” retreived from a cupboard the album reproduction was fine.
Any thoughts ?
