    thank you for the reply. i was going off the post regarding the goals of the mod on page 5. what's problematic about my treble issue is that it is only noticeable in one of my ears. i am also using sonarworks which has given me a much more pleasing sound overall, but at times that peak still shines.

    i've got the SDR mod. my dust covers off. magni 2u/modi2u as amp and dac. i've heard the new multibit model might help some. looks like the cork mod is something you have to do on your own and not sold anywhere.

    i'll give the TP trick a go and see what happens. again, real annoying at times since it's only in one ear. the other ear sounds wonderful!

    much appreciated for all the input.

    I'm feeling like the rug mod may have narrowed the sound stage a bit, or a lot. Anyone else hear that? Sort dulls the sound down a bit, maybe too much for my tastes.

    For the treble peak definitely add a simple cork cutout from the original Anax mod (found on Innerfidelity). The liner mods are really more of a midrange, overall tonal balance mod than helping you with the treble spike. It's very strange though that it's one ear, perhaps check if you've placed the SDR properly, @sorrodje wrote an extensive guide on how to place it, it might have something to do with that.

    @AllanMarcus this was exactly my problem. http://www.superbestaudiofriends.or...800-mod-formerly-btamod.254/page-9#post-63487 my cutout might fix that problem for you. It addresses the same things as the SBAF mod but simply with more air.

    After months and months of material chasing and going after the perfect mod I've found piece in SDR + SBAF (with my own cutout) and just a bit of cork around the ring to work best for my needs (including blind testing with a friend's HD800 with different mods to see what we like most without being biased, interesting topic actually haha).

    very interesting. anyone else find the SBAF original cutout makes the sound too closed in?

    maybe Im way off, but the small cutout Jun and Skiring seem to prefer would only treat the first reflections points. if there is such a thing as first reflection points in the hd800 cup.

    bringing the rug close to the driver would only be useful for secondary reflection which are not problematic... maybe im way wrong about that though lol

    Although we didn't feel need to blind test whatever noted changes,
    I did similar with a friend hd800.

    We would keep one HD800 with whatever mods were unanimously agreed,
    and then used the other to experiment and then compare to first.

    If change was improvement we added it to first set.

    Was fun but too much trouble.
    Anyways,
    Definitely an advantage to having an extra can.

    I have borrowed a friends HD800 which I am also modding for him with SuperBAF and SRD. How do you re-install dust covers with SuperBAF in place? There doesn't seem to be enough room behind the pad to get it seated correctly...

    I removed the pads, installed the dust covers, then replaced the pads.

    Personally I don't find the dust covers necessary with the SBAF mod, but when I tried it was possible to shove them in with the pads on, albeit with a slightly imperfect/creased fit. Just had to tuck the edges of the dust cover well under the pads. I also tried putting pads on last and that was a nightmare fail. From different methods expressed here, clearly ymmv :).

    Thanks @Serious, I was able to get hold of SBAF material.

    I made the cutout more then a third smaller then the original so that the metal ring is uncovered by the SBAF.

    After a couple of days, I can say the HD800 seems less bright and is less fatiguing. I can listen at higher volume without getting tired!

    the treble is still too bright but no longer untolerable! I also feel the midrange gains in focus, its bit less recessed which make the sound more dynamic.

    ive been living with the hd800 + sbaf for a week and im blown away

    the harshness have disapear. i cannot believe how smooth the hd800 modified sound. Im searching for harshness but its gone. completely gone!!!

    SBAF remove harshness, fatigue and make the hd800 sound lush. its not even clinical sounding, i find it very relaxing where as before with only the SDR mod it was still a bit over harsh

    Ive cut the cut out by half as i found that the original size made the sound a little soft.
