I’d challenge anyone to A/B a 16bit 44kHz sampled digitization with the original and tell the difference consistently. This is one of the reasons I love pbthal vinyl rips, his rig is awesome, I could never afford it, and it captures the sound I’m looking for. The 24 bit 192kHz vinyl rips on torrent sites are chasing ratio IMO.
