Here is a link to a forum form DIYMobilaudio.com, which has a download for a set of Focal demo discs. I have recently upgraded my system in the IS350, and these tracks are absolutley amazing! Anyone looking for SQ should be all over this. These cds will show you just how good or bad your system is. Someof it is "elevator" music, but with the right system, it is quite captivating. The downloads are zipped files, and I used 7-Zip to open them (free). Once opened and moved to iTunes, I was able to put them on my iPod. They are absolutely amazing tracks!
