I tried the trial version of Pure Music for 15 days and now I'm trying the trial version of Decibel. In my system, Decibel wins hands-down. Now I will admit that I might not have tweaked Pure Music as well as I could have, but Decibel clearly improved the music in every way possible. The downside to Decibel is that you have to load tracks into the player before playing them, which takes away much of the spontaneity of playing music from the computer.
