@ All of kind users who helped me with their replies   Thank you. At last I made my choice and decided to go with HE-400. It seems to be the best choice. And about amp I would go with Fiio E17 or Objective2.   Peace.

Wow!!! thank you.   I've never heard of this site before. It's graphs are great.   But some of it's reviews seem strange. For example if you count negative points (based on your criterion) of Audeze lcd-2 & Beyerdynamic T5, it's even more than Audio-technica M50 (14.5 negative point...

@extrabigmehdi   Thanks. Quote: I know I can't. I only wanted to make things a little bit more objective.   @TMRaven   Thanks. -------------------------------------------- I'm curious to know if amping or changing pads of DT880 can help it to sound a little bit less...

and it is 30 Hz & 300 Hz square waves of HE-400:

@extrabigmehdi   Thank you for your detailed answers.   If we want to talk based on graphs, as far as I learned in this 24 hours (I'm not sure at all)(I only talk about my 5 top choices):   Hifiman HE-400:                                                                 ...

and also, can someone explain, why Denon D7000 has such a difference with HD800 & Audeze LCD-2 & even with Dt880 and D5000? I can't understand it.   Thanks.  

@our martin Thanks for all of your helpful replies.     @extrabigmehdi Thanks a million, dear friend. these graphs and your analysis were really great.I'm doing the same thing with others headphone too, but I have some questions.     Quote:   &   Quote:  ...

@goldoon & extrabigmehdi   I've asked Mike's (Headfonia) idea and here is a copy of our chats:   (Me)1.Hi Mike, I’m looking for the best & most natural-sounding (a headphone which doesn’t add external qualities to the music as much as possible) headphone and an amp for about 600 $...

@our martin   I've heard many good things about this one and I think It would sound good with HE-400. Thanks.

@our martin   Thanks again, dear our martin for your helpful replay. Have you ever used Matrix M-stage with HE-400?

@extrabigmehdi   Thanks.I've heard Sony MDR-SA5000 some months ago, and as I remember it wasn't that brilliant.   @catscratch   Thanks for all of your suggestions and words.   @our martin   Thanks for your vote to HE-400 and about Graham Slee Novo, it seems really good but it...

@extrabigmehdi   I own Sennheiser HD-280 PRO, Sony MDR-XB500 & Sennheiser HD201. But none of them can't satisfy me.They lacks the clarity, neutrality & almost all of my desired factors.

Thank you.     Quote: Amazing analysis.     Quote: HD600's are really popular among ambient listeners & I still place it in my top 5 choices. But I'm not sure about Stax.I don't know if it's that good that some people say or not.
