Wow, first impression... Huge bass! 70mm drivers are massive. Anybody (preferably a basshead) have any recommended tracks to give these bad boys a test?

They showed up yesterday and wow! I love them so much. I'm using the FiiO E11 to amp them. Their clarity is exactly what I wanted for my first step into the hifi world and Flacs are just so dreamy. I'm in love, they're so comfortable and light on my head. Any other headfi'ers love their 598s?
