A typical pressed commercial disc is cheaply produced, and it's really not an ideal reading medium. I remember a conversation with the CEO of wadia at the recent detroit meet with a bunch of the other attendees about how wadia was striving to get all the information OFF the CD. Increasing the percentage of the disc that was actually read by the player, in order to increase sound quality, and they were working on it HARD.
Most commercial CD players only get 1 chance to read the data, and if there's an error reading it, they only get 1 chance to read the error correcting info. A typical cheap CD-rom in a PC will have as many chances as it needs, because it doesn't need to play the disc. It doesn't matter if it takes 20 minutes to rip a 4 minute track, it can afford the time.
And then burning those hard to extract and hard to read bits onto a very high quality disc will then make it so that you get fewer read errors and fewer necessary corrections in a commercial player.
It's all about how much of the data you can read, and with a typical pressed disc in a typical CD plater, it's just not as much as with a good disc.
In theory, 16bits and 44.1 khz is enough to reproduce EVERY CONCIEVABLE WAVEFORM up to 20khz and with a dynamic range of about 96dB. If you are concerned with music that has less than a 96dB dynamic range (which is most music) and has no information over 20khz, then redbook records all the possible information, and there's no possible theoretical gain from going to any other medium, vinyl, SACD, DVD-A. They're all unnecessary if you don't need over 20khz or 96dB. But you still need to read all that information, which is key.
