And I thought I was the only one that used Hum's DIH CD... Very dynamic recording, and some sound effects even, just to throw you off... gotta love that helicopter roaring overhead at the end of the one track...

Actually, I like to listen to Sarah Mclachlan's I love you on her 'Surfacing' CD to test the sub, VERY low tones, rumble the whole car with a single 10".

Pinback's Hurley on their self titled release is great for clarity in the beginning, dueling semi-acoustic guitars really help pick out dead frequencies. I also have a live version of Modest Mouse's Grey Ice Water that is great for clarity.

And when I just want to listen to the tunes turned the whole way up? I break out The Tragically Hip. Someone mentioned Locked in the Trunk of a Car which is a great tune, but they have so many more that are better, especially on their 'Phantom Power' and 'Live Between Us' CD's...
