hm. I tried listening to a song in WMA lossless vs 128 mp3.

i think the earphones did create something of a choke point. I noticed improvement definitely. Particularly in the background. I could hear the instruments clearer. it was very interesting.

How good are the px100's at playing rock? the only cd I have is of a local band so its not like they were the *best* choice for ripping to wma lossless but, it was interesting.

The px100's may be a good choice even if they don't lead into audiophilia because I wouldn't mind a better set of headphones then these earbuds I've stuck with forever.

How badly do the px100's leak sound? apparently the grado's are almost like speakers.
