That said, my Mind is not really done about this subject. I "feel" different amps bring something more complex than simple EQ but i'm not experienced enough to be sure. Headphone audio experience is not only a matter of Frequency response. it's a bit more complex so why EQ should be the only parameter to fix ? That's my question.
There's more to it than frequency response - absolutely.
Re-verb, decay, harmonics.... some amps are fast... some are slow... etc.
I'm just saying that it's sad to dismiss certain dac/amp/headphone combos just because they turn out a little bright and a simple EQ could have solved that in two seconds.
Take my Anedio D1 & HD800 combo for instance. To me the combo is absolutely fantastic, there is so much detail and texture that it literally feels like I can reach out and touch the notes in front of me. However - the overall tone is a little on the bright side and can be fatiguing. So I made a gentle EQ curve where anything above 8k is -1 dB, anything over 10k is -2 dB and anything over 12k is -3dB... it's subtle but very effective and to me it brings the tone down to where is should be. Then for electronica I have a different preset with a +3dB bass boost, fantastic for trance/techno etc.
Some people own different headphones and switch between them for different genres. They have grado's for rock, ultrasones for trance, sennheisers for classical etc. I find that the HD800's are so good that they just need a gentle EQ nudge and they can be perfect for anything.
