Headphones frequency response vs. amp frequency response

post #1 of 4
Thread Starter 

Hi, I have been reading a lot about Sennheiser HD 700. Apparently, they are OK to be driven from a portable (not very powerful device), but for best results one should use a DAC/amp.

 

Now, I found a reasonably priced DAC/amp: Musical Fidelity V90-HPA. Here's my problem though: The frequency of the headphones is 8hz-44khz. The frequency of the aforementioned DAC/amp is 20hz-20khz. In other words, the headphones have a wider frequency range than the amp.

 

Does that mean the DAC/amp is not good enough for the headphones? Would I be losing some quality? Thanks for any hints. (Apologies if this question has been asked before; I couldn't find anything related.)

The human hearing range is from 20 Hz to 20 KHz, and frequencies over 17 KHz are hardly audibles for most people.


In other words, we don't need 8 Hz - 44KHz bandwidth.

No.

Frequency response has nothing to do with audio quality. The average a human can hear is 20 to 20k. While the headphones can provide low frequencies lower than what you can probably hear and piercing high frequencies beyond what you would even want to hear, you would probably not notice a difference with the range cut off. If you do have different than average hearing abilities, in my opinion extreme frequencies wont necessarily make the music more enjoyable at all. The only thing that makes an amp objectively good enough for headphones is if they provide enough power to drive them.

Thank you for your replies, guys. You are saying we don't need such a wide range because we can't hear it, but I remember reading online that we can feel it, so that's why it matters. Is that true or a myth then?
