    @Marvey: When you get back and start on KISS round two, a bunch of us would be curious to see measurements using Second Skin Damplifier Pro instead of Dynamat Xtreme. Second Skin is now selling a 3" x 5" piece, presumably due to SBAF demand for their other sampler packs for headphone modding. Happy to buy one and send your way if you'd be willing, just let me know. Won't need the Creatology foam since it's already black.

    Marv, can you sub in bituthane since it's so cheap and take measurements too? Oh, and old edead paint on mass loader, CLD, and maybe some sorbothane since you're both absorbing vibration and mass loading?


    Oh man. I just bought like 10 extras from the UK so I can mod mine, haha.

    Don't be a smart ass. Damplifier Pro is an objectively better damper than the de facto standard Dynamat Xtreme and is both cheaper and easier to order in smaller quantities. It also looks better and does not require the extra step of Creatology foam or Sharpie to do so. Many of us have already done the mods with the product, but haven't seen measurements with it. If @Marvey is going to redo the KISS mod in its entirety on a second pair of headphones, I see no problem asking what I did above given it would cost him zero additional time or money.

    Re: your earlier comment, your statement that "[m]ass loading the magnet is a pretty different tactic from previous mods" is blatantly false. Dampener application to the magnet has been a part of the SBAF mod trifecta since the beginning and was refined in a thread you commented in yourself. See (source); (source).

    1. Acoustic radiation damping (absorbing vibration and converting it to heat) and mass loading (adding mass to lower the resonant frequency of a material) are different concepts. By his particular placement in this mod, Marv is trying to achieve both in this application. I know that damplifier pro has been used to good effect previously by you and others, but it's 20%+ lighter, making it inferior at mass loading and we're trying to balance the two. This isn't a car, you actually see benefit in the time domain from lowering the resonant frequency of materials in a headphone.

    2. I've used every mass loader and CLD out there over the course of 18 years working on car audio and speaker projects. They all have different properties. If you want to experiment, go ahead, but it's a lot of work to get the mod done several times and take measurements on each iteration. As an aside, if you're interested in trying different materials, consider regular dynamat. It's 30% heavier than the xtreme making it a better mass loader. It's not designed with damping in mind, though. The combination of weight and less effective damping make it significantly worse in car applications, but it might be something to try with headphones.

    3. Don't reference your own post when talking about something being objectively better for an application, especially when you don't have real world measurements to prove it. We actually consider all of these different factors when thinking about mods.

    Damplifier Pro is spec'd at 0.6 lbs / sq. ft +/- 5% (source). Dynamat Xtreme is spec'd at 0.45 lbs / sq. ft (source).

    Re: your third point, within my post I linked, I cited a post from Second Skin directly comparing the two products. For ease of reference, per the sources cited in this post:
    • Thickness: Dynamat Xtreme is 1.7mm vs. Damplifier Pro's 2mm
    • Foil: Dynamat Xtreme's foil is 4 mil vs. Damplifier Pro's 6.5 mil foil.
    • Butyl layer: The Xtreme spec sheet does not specify its butyl layer's thickness, but the post I cited above says that Damplifier Pro's "adhesive has a higher rubber content, and is about 20% thicker than the adhesive on the Dynamat Extreme."
    By my reading of the spec sheets, D. Pro is both a more effective mass loader and damper.

    First, I'll eat crow on getting the weight wrong. I was quoting from memory.

    Second, I'm done playing nice. Go f**k yourself. Your self-righteous, self-important over-indexing of threads, pontificating loudly to everyone who will hear and general policing of the forum is annoying as hell and doesn't change the fact that you know fuckall about physics or acoustics. Parroting shit you've read doesn't make you the expert on the HD6XX or whatever the f**k topic you're so interested in this week.

    Log off SBAF, read a book, spend time with family or take up a new hobby. If you chose not to and keep up the passive aggressive, smarmy bullshit you're getting a temp ban.

    He's been annoying a large number of the mods and admins for a long while. I've gotten enough complaints that I figured a more obvious message would be useful.

    The shit you see*. Things could happen outside, too. Small things that add up.

    After cooling off and reflecting some, I respectfully disagree that your message yesterday was useful.

    What was useful was our private conversation three weeks ago where we hashed out most of the issues you publicly raised again yesterday. You informed me certain mods had grown tired of the way I was handling some Randos' new threads, and I apologized to you and to a friend of yours I unintentionally hurt. I told you I agreed with you and referenced the constructive conversation re: a path forward already taking place in the Club Room thread. You instructed me not to pursue those plans/discussions further. Since 11/15, the date of our last PM, I've done as you instructed.

    In my opinion, you're conflating these past issues, which I considered resolved, with what happened yesterday in the KISS thread. I believe your negative feelings about me color your interpretation of my posts, reading intent into them that is not there. I was not being passive aggressive in the KISS thread. I was disagreeing with your assertion re: @MikeD's post and defending my claim that one product was objectively better than another. If you and/or Marv don't want to use D. Pro that I was willing to buy for KISS round two, that's totally fine. It was only an offer, so let's forget it.

    I agree that I'm not an expert on the HD6XX, physics, and acoustics. I've never pretended or claimed otherwise. Instead, I source things out so people know where the information I get comes from. What you call "parroting," I call "citation." My sources frequently include your, and other admins', content.

    I created a couple compendia recently because I thought they would be helpful resources for both me and the forum, not because I'm self-righteous. Others, including admins, encouraged me to do so and thanked me for it. As we discussed in our recent PMs and as has been discussed elsewhere, these resources are to help site visitors and members easily find information without needing to repeatedly ask the same questions in a product thread. These projects help me file things away and get them out of my head instead of trying to remember where I found something as specific as a single sentence. I know where to easily find the information later and don't have to go off of memory. I also enjoy doing it. You may find my work over-indexed, self-important, and not useful, but you are not the target audience. These projects are also not relevant to our discussion in the KISS thread yesterday.

    From my perspective, you told me yesterday that:
    1. I'm facing a temp ban for "forum policing" despite complying with your instructions re: the same since our 11/15 PM on the topic;
    2. I'm facing a temp ban for volunteering my time and utilizing my training to create helpful forum resources that will hopefully further reduce forum noise;
    3. By disagreeing with you twice in the KISS thread, concisely writing why, and citing sources backing up my assertions, I'm being passive aggressive and smarmy; and
      • Note: In my last response to you, please note the "[snips]" which mean I was not addressing, and deferring to you on, those arguments. I was conflating mass loaders and dampers without even realizing I was doing so. I hadn't yet looked into the mass of both products, so it was a catalyst for further research from which I then shared findings.
    4. I'm facing a temp ban if I don't log off the site, read a book, etc.
    With you, it feels like I'm damned if I do and damned if I don't.

    Let's be honest. You don't like me or my content and have it out for me to a certain extent. I think you're usually cantankerous and often disagree with your moderation style. We're both adults, however, and I'd like to move on and peacefully coexist.

    i liked that review Zonto did on youtube where he listened to some entry level stax for the first time and had his mind blown and all i could think was what a pedo perv he was based on his disgusting monitor wallpaper.

    Was that your favorite one? I liked the one he did where he conducted a sighted AB test between the Bifrost Multibit and some shitty Emotiva DAC by listening to a weeaboo song and switching between them every 5 seconds, only to come to the conclusion that all DACs sound the same.

    Is there some joke getting lost in translation here? Surely @zonto isn't making those Z Reviews...
