It's random, mine also looks very similar to this... And I've seen another 20k pair with the same curve.

Because all the HD800s are the same within manufacturing tolerances.

I  don't hear it, or it's not significant. I  tried to tame the treble with eq, only to revert it later : not much interesting.

 

Perhaps sibilance is a bit emphasized with some recording, I'm not sure.
I'm especially disappointed while listening to Mylene Farmer, lot of sibilant tracks.

Not unbearable though.

The comb effect looks pronounced to me, but you might still enjoy it. The bs2b has no comb effect, but I  didn't like it.

The new version has a comb filter to deal with that effect.The filter can be turned on or off as you choose. I don't know how you took that graph but the HRTF setting and distance setting can really muck things up if not set to your ears. Any measurement you are taking would not account for the effects with your specific ears. The point is, we all hear differently.What your graph shows  would represent only one set of settings and without the effect of your specific ears. If you turn off the HRTF function and the room function and set this distance to 0 you would get a reasonable graph without ear interaction and only the crossfeed which is always present. Took me a while to understand how this works. I agree with the fact that you can really destroy the sound with the wrong settings. The head function alone is probably the most important setting.  It works for me and when I use the bypass to check the tonal characteristic when set to my ears is identical to no Isone at all.

Was very apprehensive when I bought my HD800 with the serial number of 00854 because of early production model, sibilance and non existing bass etc.

Luckily they came with a Cardas cable and lo and behold.....they sound terrific.

Also,just received a Norse adapter so I can use my balanced LCD2 ALO chain mail and things improved even more.

Needless to say that I have just sold the LCD2.

So I think with the right components, there is no sibilance or lack of bass etc.,in fact I do consider the bass superior to the LCD2.

^^^ BINGO!

But if you wear them backwards, you will hear "Paul is dead" instead of that bump in the frequency graph. Really!

It's been stated that the variances in the FR charts themselves are reproduced simply through minute positional adjustments when measuring the headphone. People are seeing these wildly differing plots and speculating on a re-voicing of the headphone. It's more likely that slight variations in certain frequencies (<1dB and within spec) and the right upstream components are coalescing to pass the Goldilocks test.

Are you being deliberately obtuse? I was agreeing with him.

post #1166 of 24295
I was just trying to make a lame joke -- that wasn't directed at you at all man. Just a joke about what a joke the FR charts are in the first place. Sorry if I somehow offended you.

You forgot to add the sarcasm meter........

 Honest question: I KNOW my Bifrost is the bottleneck in my chain right now (Bifrost->V200->HD800), but how much of a bottleneck. Am I going to see a huge improvement all around if I move up into the $1k DAC range? I really like the Concero, but now I hear they're going to release a balanced version? I feel as though the V200 is really bringing out the Bifrost's true colors. Opinions welcome.

I thought the upgrade was easily justifiable. Concero is $200 more than a Bifrost w/USB & also comes with an Apple remote and USB power plug and lots of neat features.

 

Bifrost is probably good enough for most rigs, but once you reach HD800-level resolution it is too limiting IMHO.

post #1170 of 24295

 Ugh. Well I need to get rid of the Bifrost first and have had ZERO interest in it. It's pretty much brand new. Oh well. Maybe I'll sell some more gear and get a real decent $1k-1.5k DAC... Seems to be plenty in that range.
