PS: I often heard CD releases of vinyl or remastered CDs that simply had a bad sound quality. It's impossible to fix something that is missing with an equalizer. The sound quality of CDs by hook or crook is borderline, so a CD doesn't forgive a bad mix. Note, that a lot of this 90s music was produced for vinyl and without loudness war mixing, so it's likely that they made loudness war remixes, or they remixed the bass to be ok on a mobile phone.
