So my HE-400 arived before 3 days, and I am impressed. That's my first pair of Cans, so I think my wallet will stay empty . I bought them from Amazon.de for 400 euro, but I'm sure they deserve every cent. And now it's coming the next step, I need a good amp for them, so can someone recommend me a good desktop amp for around 300 euro. I know that I can drive them with Fiio 17, but i want to spend my money for something what I will use in the future, not just for this cans.
