I've tried Sox for de-emphasis... I burned the resulting WAVE files to a CD, then compared the CD to the original, pre-emphasis coded CD in my Oppo player. Hmmm.... anybody tried that? Do you think the reverse EQ curve applied by Sox is perfect? I had the feeling that the sound was better on the original CD, kind of muffled on the de-emphased CD.
I haven't tried it myself (I only have a few discs with PRE, The Wall and some Sabbath Castles), but in general my SoXed files sound a bit muddy. From what I've read, you're not alone. Gee, do I have to install iTunes? Sigh.
