Thanks a lot for your help! I have decided to get the Fidelios x2 thanks to your advice and now consider the Objective 2 as a great amp for it!

No, nothing specific, I'll rely on your more professional judgement :)

Wow, of you could do that for me it would be really great :) Because I myself have no such possibility. If you will do that could you tell me what sound source you were using too? Looking forward to your response.

And what do you think about the AKG Q701 compared to the Fidelios x2? I know the Fidelios need no amp, but would they benefit from one? If yes, recommend please :)

I very much appreciate your help. I mostly listen to active kinds of music like pop, rock, instrumental, a bit of heavy metal and a little bit of classic . Which ones would work better? The fidelio x2 with no amp or the dt990 with an amp? I am absolutely sure, you are getting irritated with my...

I am sorry for the misunderstanding. I will be using the DAP plugged into the phone, that's what I meant. Or did you mean that the sound would still get much better if I use an audio player (eg x5 or something) with the DAP (eg e12) if compared to the phone plus the DAP? If yes, will that be a...

Yes, it is a portable setup, I have an Asus Xomar Dx audio card for my computer though, will that be good too? So if I get the e12 I need no other player? Just plug it into my smartphone(htc one m8) and that is it?

So, I decided to get myself a pair of new headphones. My choice fell on the Beyerdynamics DT990 250Ohm version. My question is: will they be performing with my HTC one m8+fiio e12? Or should I get something like Fiio x5? Note that my budget is limited. I also considered the Sennheiser hd598 and...
