I know that this has probably been asked about 1000 times on these forums, but what I am after is slightly different. I would like to know what Rock CD's people use to test there system. Rock music with a lot of bass. My Favourites are: Pitchshifter - www.pitchshifter.com Nine Inch Nails - The Downward Spiral Stabbing Westward - Darkest Days Has anybody got any other recommendations???
