HiFiMan HE-1000 Measurements BETA - Official

HiFiMan HE-1000 Measurements - Official - Stock headphone.

  • Channel matching is excellent. Slight deviation in bass probably a result of pads / alignment. I didn't bother spending a lot of time adjusting. They already looked great enough, especially for orthos.
  • Distortion is excellent. TP mods remove 4-5kHz distortion spike. See below.

TP Mod to tame 7.5k peak: http://www.changstar.com/index.php/topic,2440.msg67729.html#msg67729
Subjective impressions: http://www.changstar.com/index.php/topic,2386.msg67709.html#msg67709

(Original "measurements preliminary" posted 5/20/2015):

HE1000 L channel stock.
  • Note "ortho wall" near 5kHz. All orthos exhibit similar behavior. It's not audible and absolutely nothing to be worried about. Here a link on the ortho wall phenomenon: http://www.changstar.com/index.php/topic,1726.msg45968.html#msg45968 I think there are other threads and posts where this is discussed.
  • Of some minor concern is the 7.5kHz peak, which correlates to subjective impressions from a few peeps. My early subjective impressions can be found here: http://www.changstar.com/index.php/topic,2386.msg67709.html#msg67709
  • The good news is that there is no long lived ringing / ridge at 7kHz. This means it ain't bad.
  • Bass extension looks to be fabulous
  • CSDs overall clean with fast decay from about 1kHz up.

Ahah! So there is that progressive treble rise that I found slightly annoying.  headbang

Do you think that possible roll-off in the extended treble might be part of the minor tonal compression?

Can we get lower noise floor a la 009/HD800 eventually with top down views when you get a chance?  :)p5

Looks promising, I might have to get my hands on one to play with. So far it's only this, HD800 and 009 that remotely pique my interest.

I don't think there is much rolloff in extended treble. Take anything above 11-13kHz with a grain of salt. High treble gets really weird and directional and sometimes doesn't measure right. The "tonal enforcement toward lush", soft, beautiful, or whatever only occurred with GOv2>Magni. No such issues with Rag, Studio, or even ZD (outside of bass).

I am not having any lack-of-focus or heft issues as with ohgourami or Sorrodje, at least when using the HE-1000 appropriate. At least there's a good side. Those who prefer the lusher softer sound have good cheap options.

K, just checking. Could be a TF diaphragm thing then or something else.

Those sort of correlate with my very brief and noisy JamCam SoCal 2015 impressions. Decent bass (hitting harder than the Ethers), but a bit bright perhaps... and that's as far as I go cuz I'm not HE1K loaner special.

To be fair, I think it's the most sensitive ortho I've heard to amp synergy yet. IME with the 009 and HD800 that's been a pretty good sign for scalability and potential.

Ether has some similarity. Both are kinda bright, but HE-1000 extends lower, has more heft, and is much cleaner. The pitch of low bass tones are incredibly clean and easy to make out on HE-1000. I'm a bass player so I appreciate this. Also because I am bass player, I know better than all your other guys. And my mom is a ballroom dancer, so that makes me know even more than any of you guys. And my son met Adam Sandler. Obviously I have better credentials. And by the way, I'm not an audiophile. I'm a music lover.

Sensitivity to gear = usually a good sign.

Well, I talked about the bass here after CES and everyone who went to Canjam thought I was batshit crazy.  8) For the record, I don't play bass but I do know how to spell it and could probably draw a picture.

Each new hifiman seems to have more and more of a problem with keeping a smooth response in the midrange.
