    I have the Dekoni pads. The best quality leather pads available for the TH900. Unfortunately they make the bass too light, and they have smaller opening than the originals. I prefer my carbon foam pad fillings, but I have kept the Dekoni around (together with several versions of the Brainwavz and Stax pads).

    I did some side by side comparisons between the Purpleheart and Ebony versions a few months ago. After about 20 minutes I could hear the differences reliably. The ebony is more flat sounding and probably what I would recommend for most people. That said, I own the Purpleheart and have no desire to switch because swapping back and forth repeatedly is not how you listen to music. If I'm in the mood for a more neutral sound I won't want to listen to a TH-X00 regardless of the cup material. When I'm in the mood for a fun sound, might as well go as fun as possible.

    Hi,

    did you try the Dekoni pads which are made for the TH-900 or the ones for the TH-X00? I ordered and received some pads for the TH-X00 PH lately. Quality is great and I really liked them on the PH, but then I also tried them with the TH-900. It took away the sharpness in the treble for me, while still keeping the bass quantity. Not sure about the bass quality, I still have to compare to the original TH-900 pads. However it made me think about selling my TH-X00, since the Dekoni pads seem to fix the treble sharpness of the TH-900 for me.

    Would be interesting what you and others think about that.

    The time I bought the pads there were only ones made for the TH900. Any link? I still don't see any other pads there than for the TH900.
    http://dekoniaudio.com/?submit=Search&s=fostex (there are subjective opinion + measurements as well).

    Did you measure the bass with both pads or do you rely on subjective impression? I ask because I was surprised to see the bass roll-off with the Dekoni pads, ok they sounded a bit rolled off, but on measurements it was quite much.

    EDIT: it may be that the sealing on the coupler was better with the original pads than with the Dekoni. Anyway they are very nice pads and definitely worth trying.

    Just subjective and very early impressions, still have to check more deeply over the next couple of days. I was talking about the pads from massdrop for the TH-X00. They don't have a round opening like the TH-900 pads, but the same shape as the the opening of the TH-X00. So the ones made for the TH-900 dropped to much of the bass for you? How about the treble with those?

    Did you try the Lawtons as well?

    FWIW, Ebony version version PH. Another datapoint from Massdrop's measurements.

    Hard to say if the flatter 500Hz is because of the Ebony. It's possible the Ebony cup dimensions are slightly different, resulting in a different internal volume. Wood material resonances affect small CSD ridges. They don't flatten dips.

    IIRC also the mahogany version was flatter in that region. It's indeed hard to say why we have that notch to start with, and we don't have enough measurement data for consistency over various versions, but when measured without the cups, it's not there. Actually the TH900 would sound very nice as an open headphone (provided the treble is fixed). Hopefully next week I will get the ebony as well and then could measure it.

    My Purplehearts came and went, I really didn't like them at all. That huge mid-bass boom was the most obvious reason - it really sucked the life out of / bled hard into the mids. My D2000 has that "bassy boostiness" clearly in a lower region, it doesn't get in the way in the same way at all. (Also the sub-bass is much more present and pleasing.) Them Denons are lots of fun, still. High recommendation for fans of hip-hop & big 'n deep bass overall.

    The Denons might have some extra energy up top, but they're like a breath of fresh air (pretty close to Aurvana Live FR-wise, btw) after the boomy wool of the Purplehearts. I'm not so sure those trebles were up to snuff either - there seems to be too much coloration for my tastes, reminds me of X2. And that is not good.

    P.S. I listen to lots of rock and metal and love me some substantial subs. I very much hate messy upper bass /lower mids - mids bloom in general. I need to hear the separation between guitars and bass. PH failed hard.
