I can't listen at work, 400VDC is something you want to pay attention to. And I've been hit with 625VAC off of a 3-phase system. Not a lot of current in this patticular application, but it ain't fun, and I don't really want to do it again. Wifey works from home most days, and doesn't like to hear my music, most especially at the levels that please me. So, I only get to listen when she's not here. I, therefor, REALLY want to ENJOY my time with the system. I just got new speakers in October, and a new amp is scheduled to be delivered tomorrow. So....
That being said, I'm also waiting on the next DROP of the HD-6xx headphones, sometime in February. If she's working in the home office on a Saturday morning, taking a nap, or whatever, I'll have another option. But, as has been mentioned, you can't feel the bass through 'phones.
