Really safe answer, lol 

  That sounds interesting. Sometimes, I found out some vintage Sony earbuds in my house which were made from the time I wasn't even born. Interestingly, it was totally blowing my mind with its really impressive and decent sound. "Vintage" doesn't frequently mean to be worse than "Modern". 

Actually, the amp itself doesn't cost that much. But the custom fees/taxes, shipping cost (and, maybe, other fees of assembling for those who don't want to do it themselves) do. In EU, I am looking for this amp with better prices and right voltage, but I haven't found the right one yet.

It looks really cool. However, open back is.... .

Thank you for your info. I'm taking a look at them now. 

Thank you guys so much for your recommendations. They would be great helps for me to find out my own set-up for the HD650. Actually, I had a chance to give these cans paired w/ Eddie Current Zana Deux in a portable audio show, and the sound was perfectly beautiful. However, it's far away from my...

Thank you for your reply. Actually, I tried these cans with my O2/ODAC combo, and they sounded great imo. However, I also felt like the headphone could be even better when being paired with better amps, especially tube amps. I've read through many threads about these cans and Bottlehead Crack...
