Dude, you shouldn’t of even let the time elapse writing this post! Shoot first ask questions later. I’m glad you got them $40... that is a steal, not only because they are worth 6x that amount for resale but, because they sound bomb! I just got a pair of 570’s at Salvation Army for $60, did I really need them? No but, they had been there for a week (per date on the tag) the guy said people had been trying to haggle for a lower price but he wouldn’t budge so they passed. Huh? What? The gift horse’s mouth was looked at several times already?
Anything that says ADS is awesome. If it says ADS and it’s not being sold for retail value it is worth picking up. When you start to collect too many to listen to, think of other uses for them like ditching your end tables and using them in place, or put a bunch together and lay your mattress on top for a nice ADS boxspring. Maybe some nice l300’s as book ends, a 910 cab for the dog house, or if you find a single let your kid stand on it to reach the bathroom sink....
