This is a very good practice. I do the same. Again, if the music had ever been saved at a bit rate lower than that, just keep it at its lowest bit rate. Once compressed, there is no bringing it back to its former glory. I really enjoy iTunes gapless setting. It does a pretty decent job. GL with your music, I am OCD too and it ***** having some music that is really quiet or really loud. Out of the headphone jack, I see this still with a few of my songs and try to replace them asap. When using the digital connection from the dock on the ipod, it usually levels the songs out properly (it ignores volume changes made with the track editor). I might suggest as far as home listening and in the car utilizing a deck that can use the high speed connection and get a dock for the house.
