I recently picked up a pair from Newegg.ca with Free shipping from their ebay listing. Fast service. Amazing headphones, ridiculous considering the price.
Having owned the Amperior once prior, and owning a set of HD-25 1-II for a decade, I can say that while the Amperior may lose a bit of the balance the HD-25 has, it has superior definition and clarity top and bottom. They were a bit sharp initially, but seemed to have tamed, well that isn;t entirely true, some tracks are a bit sibilant and sharp with the Amperiors treble.
Note: If you like electronic music, you will especially love this headphone as a portable. It's still a solid all-rounder, and I concur with Tyll's review http://www.innerfidelity.com/content/most-excellent-sennheiser-amperior-and-hd-25-1-ii
I chose the blue, as Sennheiser is only producing the 'Aluminum' edition of the HD-25. The blue will be a bit more rare and they don't stand out as much the silver. They are more like the 'classic' HD-25s.
