Well the earlier uncompressed "used" ones are now demanding far more than what they were new on ebay. So you know the streaming companies aren’t going to shell out for those. They are going to go for the cheapest they can get, which unfortunately is going to be the later/latest highly compressed versions.
Just look at this, which do you think the streaming company will end up getting 28 years difference for the same CD only the oldest one is uncompressed. Look at the shocking difference in dynamic range!!
