Originally posted by KikeG Vinyl records have another form of compression, which is somehow "dynamics" compression at low frequencies (RIAA eq.) , in order to overcome the mechanical problems at the playing stage.Note that the digital "compression" we are talking about at this thread, translates from a technical point of view into SNR or dynamic range. Note too that the dynamic range of 16 bit cd-audio (~96 dB) is far, far better than the dynamic range or SNR of vinyl (lots of background noise).
