Howdy all,
Thanks for the kind words; it really was a "labor of love".
I should add that I know there are folks here who think there's absolutely nothing wrong with the stock Denon D5000. Obviously, for those people, there would be no point in doing this mod. There will always be people who like the sound of 12 subwoofers in the trunk, and that's fine.
However, if your impressions of the stock D5000 match mine, then you owe it to yourself to give these mods a try.
Alternatively, if you have only a minor issue with the Denon's bass, and wouldn't mind a little improvement/tightening, but are afraid of going all-out, I would suggest the following:
1. Do the ear pad mod. This should be mandatory no matter what.
2. Apply the circle of Dynamat (with center hole) to the smaller butt of the driver.
3. Apply the layer of Dynamat to the inside of the ear cup.
You will end up with a phone that is about half way between the overblown stock phone and the "perfectly balanced" full set of mods. It will still rattle your skull a bit, but you wil experience a very solid degree of tightening.
What I would really love to see is someone take the Denon drivers and transplant them into another headphone frame (one with good build quality), and possibly create a new larger wooden enclosure shaped sort of the like the R10s. Of course, all that is well beyond my capabilities.

It seems like the (Denon) engineers are 'ruining' their headphones on purpose to cater to the masses.. Ala, flabby, farty bass.. & Why aren't the engineers doing what Mark did? |
This is exactly what happens when you rely on your machines and measurements to tell you when you have successfully designed a product. Clearly, no one bothered to *listen* to the finished product.

Also if you think this type of resonance control mods could work well on the DX1000s too. |
The DX1000 has a different problem than the Denons. The DX1000 has two inner chabers within the wooden ear cup. One or the other (or both) of them is causing that hollow, echoe-y, reverberant sound that is so distracting. I'm not sure how to corect that, but I'd probably start experimenting with some carefully stuffed Fiberloft in those chambers. I no longer own my pair, I sold them when I corrected the Denons.

Wouldn't Dynaxorb work equally or better to absorb the driver's back radiation wave instead of Dynamat plus the foam covering the wooden cup? |
That looks interesting (not familiar with it), but I mainly chose the foam because it is porous and has holes to allow air flow. Those little foam pads still sit on the face of the driver and do cover a few holes each. I felt using something that would allow air through might give me the advantage of damping but without overly restricting air flow.
