The playback process of a needle moving repeatedly through a groove tends to physically smooth out the waveform compared to a digital copy of the same recording. Speaking entirely subjectively, I think this makes bass sound warmer+smoother. Besides, all too often your digital sound recording isn't making use of 16-bits of dynamic range, what with the loudness war peaking during the CD era. Oftentimes the vinyl versions of albums are mastered a lot more conservatively since brickwalling the recording with compressors and limiters will cause the record needle to skip.
