Coming in late to this discussion but I have to back up Ice here. Sound compression is vertical compression of the wav file. File compression is horizontal compression of the wav file. They accomplish 2 completely different things.
There is no way that a vinyl record will have more amplitude than a CD. Originally when CDs first came out it was their dynamic range (the vertical axis or the amplitude) that so impressed people. These days the pop people especially, compress everything vertically (called hard limiting) so that the music sounds louder. There is practically no dynamic range left - the difference between the loudest parts of a track and the softest parts. I hate it
Unless These Days for vinyl was mastered completely differently than These Days for CD, the CD should actually sound a bit better. They should both be listened to on the same equipment at the same sound level to make a decent comparison.
