Re more bits giving wider dynamic range - probably better to write "more bits gives the possibility of wider dynamic range". Many recordings have a deliberately narrower dynamic range because someone thinks that's a good idea - and depending on the type of music there may be some point to that. Impressions of loudness may at first sight be greater with a narrower dynamic range, and the volume levels turned up on the playback kit - but that can be very tiring to listen to. The motivations may be commercial and profit seeking, rather than purely musical. Both CDs and SACDs should be capable of a dynamic range greater than most people would really want.
yes, totally agree. CD spec is really overkill there was never a need for a playback medium with a higher frequency or amplitude capability than that.
