...and has i changed for the better? i've been collecting cds since they first came out, and many of the first ones have a very different sound quality than the latest ones. obviously advances in mastering have changed the sound, but also producers are lately using more dynamic compression as well. older cds tend to have a dry, sometimes brittle quality to the sound, but often had better dynamics (especially in rock and pop music). post 1990 cds and remasters to my ears have a more lush sound, like there is more detail in the midrange, but often sound very compressed dynamically. sometimes the older cds sound a little easier on my ears. also, some new cds have copy protection, which supposedly impacts the sound quality. has cd sound really advanced, or is it just different than it used to be? and do you prefer the "new" cd sound to the "old"?
