Great point about how the market has changed over the last decade. What I said still holds in general, but needs to be rethought with regards to the T50RP. I think the fact that I have become more comfortable with more expensive headphones bothers me and I hate to see the market continue to move upwards.
Knowing about how market price is being driven, we should avoid buying really expensive rigs. Let's vote with our dollars! We, members of the headfi community should take a step further.
