The HD700 arrived today. $840 CAD to the door. They are quite different from the Amperiors. I don't think I have ever tried open-ear headphones before. After 10 hours of burn-in, they are sounding excellent. They are being driven by an Aune T1 /w stock tube. The sound stage is wide, and noticeably more definition in the low-end and the trebles are strong, and clear, but not overly bright. I love them.
Are they worth 3 times the regular price of Amperiors (MSRP)? From experience in home and car audio, my speaker spending hits it's diminishing returns point at ~$1000. Rather than upgrading through the price ranges, I just decided to go for my endgame. I'm glad I did. Now, I'll just roll tubes until I can afford a really nice headphone amp/dac.
