Question for you Tidal streaming guys.... if old CDs had less compression and the new copies have been heavily compressed, can you pick the release and know you are get one with some DR left on it?
In the rock genre, Tidal has a deep catalogue but most of it is the remastered versions of albums/songs.
Deezer has a very good rock selection and offers the original flat digital transfers (same as early CDs) in addition to the remasters.
The albums are clearly marked as remastered, the originals have their date of release. And it's a pleasure to hear music that doesn't suffer from high compression. Although, not all recordings from those days are of the highest quailty.
