I just got my D1001s. I listenened to them for 5 minutes and proceeded to recable and damp them.
I made my cable really short, about 24", because I intend these to terminate in my shirt pocket most of the time. The result is that I have to use a (q-jays) extension to get from my chair to my amp. I am now a believer, for sure, of cable making a difference. That extension has a definite effect on the highs (maybe more but definitely highs). Funny that it might actually be a good thing for making some cans less fatiguing.
BTW, on the subject of cable lengths, I also decided to try to do this part as rightly as possible on my D2000s. Rather than picking one particular length right off, I just ran a short bit from the cans to a 6.3mm Neutrik connector and then I made two cables with 6.3mm Neutrik connectors on one end and 3.5mm on the other end. One cable was long and the other short. I'm sure those with golden ears would be pretty unhappy with this, but I used the 6.3mm connectors because they have the least degradation of what I could find. (Technically it would be better yet with 6.3mm on both sides, but everything I have uses 3.5mm.) If I want it to go further, I use the longer cord. If it's just to something close by, I use the shorter one. No need for separate extensions (and the sound isn't changed by such a cable either.)
BTW, don't forget that even the D1000s need burn-in. As I recall, they didn't need much though. I think the sound settled at least somewhat around 40 hours or so even.
|For what these are and what they do and what I paid for them I like them much more than I do my D2000. (The D2000 are unmodded and are their way out the door because I just don't think there is any way I'll prefer them to the K701.)|
|I didn't damp the driver, just the cups. What exactly would the expected effect be? On person mentioned it slowing them down but this doesn't exactly make sense to me. If anything it seems like it *should* speed them up.|
|I put about as much polyfill in there as is shown in post #1. What are the expected effects of increasing and decreasing the amount of this stuff in there? I could still do with a little less boom and a little more punch but I would hesitate to give up any extension.|
Anyway, if you want more punch, you'll want less stuffing. In the D2000s I actually used probably more like half of what he described in that old post describing the mod. I pulled the fiberloft out as thin as I possibly could while trying to keep an actual layer (eg no big holes in it) and then I added one more layer on top of that. For me at least this got the bass to about the perfect point. The Denons definitely have a strong bass response, lol. For me this actually required a lot of toning down.
PS. If you look on the charts for the frequency responses for the various Denon headphones, you'll probably notice that they have a much smoother flow compared to most other headphones. I think this is probably a great picture of how they end up sounding so much more even and smooth.
