I was going to say you have a healthy imagination there kiddo, but then again - this is probably an all too common type of thing with pawn shops. Bottom line here is that it's all pure speculation - it's impossible to know all the many variables that led to the price tag and a pair of lonely 901's sitting on a dusty shelf at some no-name pawn shop, which by the way - was indeed a Cash America. But - I'm thinking a more likely scenario here is some guy realized his 901's were total crap - bit the bullet and sold them off for as much as he could get for them at his local pawn shop. I said $400 to $500 before, but in reality I don't think the pawn shop would have given him more than $200 for the pair - that's $600 profit for them, IF they can sell. I think out of curiosity I'll check in there once every so often and see if they're still sitting there - it's directly on my way home from work so not a big deal.
As a side, related note - I also noticed an old JBL center channel speaker I had sold to them more than 2 years ago (just wanted to get rid of it quick for some extra pocket cash), still sitting there collecting dust. Hells bells! I think those 901's have found a permanent home.
