Guys,
If you have no problem with purchasing from eBay, get some E500PTHs from there. There was a guy selling them for ~$280 new. Same as the 530s, the 530s just have better foamies, that's it, as comfirmed by a Shure engineer on head-fi.
Unlike other electronics Shure warranties the product regardless of where purchased from, 2nd hand, etc. They can go by the date code on the product, no receipt necessary.
RE: the $1500 Stax setup... I had about $5k sunk into this hobby as of last year, sold off much of my setup to buy a motorcycle. There are guys on head-fi that have several $10k into it - drink the kool-aid, I know you all want to.
Once again.

Oh yeah, and don't mention any love for Bose on that site, you will get ripped a new one.
