Most people don't see a diference between the CD and MP3, but probably because never do an AB with a good listening condition... I've realized that doesn't make much sense use $#0000 to record if people will en up listening 128kbps MP3 but my relief is to work for me and what I record and mix should like me and not who is listening in MP3 in mono because he didn't want to plug another wire, so if you listen one guitar and not the other is not my problem.
It's sad today see all this MP3 laying around with so huge hard drives and fast internet conections... IMHO is time to get something better than CD and start using DVDA or something new as comercial medium... The diference between 96/24 and CD is huge for me, maybe more than a good (256 or 320 kbps) MP3 and CD.
