Thanks for the suggestions! I think ill go with the ATH-A900X when I get more money.

Thanks for the information, I will buy the e17s. Also what headphone would you recommend I buy if i sell my other ones off?

So e17s have better sound quality than the e10s?

How good is the e10? And is it more worth it than the e17?

Hello, I recently joined and would like some suggestions on any cheap amps/dacs that go well with m50s and hd 558s. My budget is around 150 and would like suggestions. I will be using it with my laptop. Thanks in advance!
