Good job on the review mate, ignore the troll and enjoy your amp.
I have the O2 running MadDogs, JH16, JVC S500 and ,MDR-F1.
With the exception of the F1, it sounds great with all of them.
Yep, I did a O2 vs. FiiO E11. No contest
Everyone is entitled to their opinion. There's no need to attack someone just because he doesn't agree with you.
This seems to be the problem. If someone doesn't like the sound of a headphone with a flat, low distortion amp the person doesn't like the headphone. Saying it's the amp's fault is absurd.
Been keeping up with this thread, again great job randomkid. With all this different talk about neutrality and whatnot with the HD650s, I just have three questions for you guys and hopefully the OP would not mind since it is relevant to the thread.
1) Does this amp drive the HD650s efficiently/properly?
2) If #1 is "yes" do they synergize well with this amp (not too much of anything in the spectrum and clean sound)?
3) What sources are you guys using with the O2 & HD650?
Thanks in advance...
