There are amateur mixing engineers putting out better mixes than on some professional releases.
Even though a lot of these amateur mixes get more adventurous with placement, they lack the kind of sonic refinement that a true professional will bring to a project. Plus, the amateur is usually doing the mixing for themselves so they can do as they please, whereas when a paying client is involved, they get their way.
I really haven't heard any amateur mixes that measure up to the ones mixed by people like Steven Wilson, Elliot Scheiner, or Bob Clearmountain.
