“Reduced information“ means different things to different people. For the electrical portion of the system Signal to Noise ratio and Dynamic Range are very good measures of “information.” Theoretically, digital should win hands down, you know, with stated SIGNAL TO NOISE ratio of at least 90dB and DYNAMIC RANGE at least 90dB. But things don’t always work out in the real world like they do theoretically.
Playback systems have inherent issues as I’ve oft pointed out that reduce the theoretical values of SNR and DR to where LP playback competes with CD playback, there are too many variables to say which is better in terms of “information” retrieval. It’s apples and watermelons usually . The industry further exacerbates this problem by overly compressing CDs and LPs. So, you can’t win. Other harder to define aspects of sound like sweetness, air, tone, transparency, etc. come into play as well, and can also be considered “information.”
