You could. Amazon's price for the HD 650 went up to $495 recently. Some speculate it's in preparation for the release of the HD700, because Sennheiser doesn't want the next model down to be so much less expensive. That doesn't change your point, though, which is that the discounted price is still significantly lower than its list price. It would be nice if the price for the RS 220 gets discounted, but unless that happens almost immediately, I don't think I'll be patient enough to find out. I don't particularly relish spending $600 on the set, but if it's as good in reality as it looks in theory, it will be exactly what I'm looking for.
