oh not that arguement again. a sample of a 156 people does not a blanket statement make. especially when that sample comes from headfi of all places.
Amazon is one of the cheapest places to buy the 650s right now and one of the most expensive to buy the 600's - their 600 price is
not an indication of popularity. It's nothing of the sort. Besides which, the 600's were £180 in April, you think the increase since then is because of their sudden popularity?
Amazon are normally amongst the cheapest for just about everything they sell, so right now the 600 pricing is an exception. SO, either the hd600 price is a sign of things to come and the 650's will increase by a similar amount, or its a result of constrained supply and it'll soon drop back down again. Just wait and see
