Grant, I'm familiar with what MP3 is and what it is intended for. In my past life, I was a pre-sales Systems Engineer at Apple. My point was that there are lots of digital formats. When does *digital* become accurate? better than LP? At what sampling rate? If a lossless codec is used, theoretical S/N and THD are influenced by the playback mechanism, the hardware. Same with frequency range -- it's not just the format. Further, I'm curious as to why you are able to state that MP3 isn't suitable for "serious listening" while millions of users swear that it's just as good as CD? In fact, that they can't tell a difference between the two? Let's not throw around "ignorant" -- I find that very offensive.
