Hi, I was just at http://www.xiph.org/ogg/vorbis/listen.html
and they had comparisons of the different compression types. The thing I'm intersted in is the different songs this person used to show differences in the compression type. are there cds with mixes of different songs, styles of songs that put speakers to the paces? a good cd to test all the ranges of the speaker with? i have heard all my favorite cds on my spaekers and they sound great, but i'm just wanting to see the abilities and limitations of my speakers a little better
