Hi, this is how I increase the sound on my ipod classic (they definately have turned the sound down on the new model) . Before downloading to itunes go into edit, click on preferences, then you will see in the box, 'sound enhancer', set this on high. this will remain set on high until you change it. Once the album you have selected is in itunes, select the album,click on file then click on get info. An instruction will come up saying' do you wish to change settings' or something like that, click yes and then a box will come up that includes the volume adjuster. Set this on high and click ok. This will reset the whole album. Unfortunately, I cant find a way of permanently setting the volume adjuster so i do this for every album. (Clare posted the instructions for me on how to do this).
Also, I cannot praise enough the iw30 docking station. The build quality and even the packaging, belie its £15 price tag. Everybody should go and buy one now.
