So I finally decided to Sony MDR MA900 and they are awesome! Never heard so much space, I am really happy, thank you guys for your help :).
And I have decided to buy a headphone amp cause still with these headphones I need to turn up volume higher than before. And in addition I want to buy some AKGs in the future. I read on MLE guide about Fiio E09k and Fiio E12 and want to know, which of these will be working better with MA900 and with potential AKG in the future. Or if you think that there will be better choice, tell me about it please.
Thank you for any advices.
