focal has some awsome demo discs, they are mostly audiophile recordings,with a variety of styles. the drum solo is my personal favorite, as it shows the stage hight, width,tonal accuracy,and dynamics of any system(a definite must hear)
there was a post on the sq section in reguards to some audiophile selections.if all else fails pick up a copy of -chemical brothers,junky XL,the crystal method.they all have some crazy bass,sweeps& tones.happy listening
