Not saying I'm going to buy these anytime soon, but if money were no object these would be on the top of my list.
- Sennheiser HD 800 S: I have always loved the clean Sennheiser sound, and these are some of their best.
- Mr Speakers Ether C: Closed Planar Magnetic. These would be a replacement for the Alpha Dogs. They would also probably be the only headphones I would need.
- Stax SR-009: Electro Static headphones often called "The Best Headphones". You could also say the most expensive. They even require a special amp to play them.
- Sennheiser Orpheus: I would just like to hear these. I'm not sure I would ever buy them, even if money were no object.
