HD800 Variability Measurements Starting with Jason's HD800
« on: September 03, 2012, 01:03:09 AM »
At the H3 meet, three of us, including Jason, noted that Jason's HD800 was pretty darn harsh, even with the Anax mods*. We compared threeunmodded HD800 with Jason's modded HD800 and still noted that Jason's HD800 was harsher and grainier in the treble. It wasn't like these HD800s sounded completely different. Jason's HD800 still sounded like an HD800. Just that it was a little bit worse than the other up in the treble.

To help unravel this mystery, Jason sent his HD800 (along with the review Mjolnir) for testing. It should be noted that the s/n is 16K. It's a newer HD800. Note that measurements are without the dust covers on unless indicated.

So do you guys see anything interesting? I will follow up with measurements from other HD800s.


* These were from the Tyll cutouts using one layer 2mm foam and thinner ring. Note the official Anax mod is different.

8kHz adding to the 16kHz on Jason's pair making some not-niceness?

The schiit one looks to have a mild case of the double-octave-penetration at ~7 and ~14khz.

Interesting that 6k on Jason's pair isn't a peak either since 8k is pushed up so the FR plateaus from 6k+. I would think this would make the treble sound more even, but as Mav said you do get that double octave thing going on.

Max's HD800 does sound the best - the smoothest.

Why? What's missing from the others? Is Max's HD800 an anomaly amongst the various HD800 samples you've heard?
