My Very Simple Denon D600 Mod

[moodyrn]

Well since I now like these enough for them to be keepers, I decided to do a little experimenting. There are quiet a few things I like about these cans. They're not as boomy as the d2000/5000, have a nice treble sparkle, and sounds a bit cleaner to my ears. This is all while actually having the isolation of what a closed can should have. I also like the cables and iPhone control(including Siri). But there are a few things I would like for them to do better. Though the bass is less boomy, it's still a little boomy compared to my high end cans. And the mids are still a little recessed. So I would like just a little better balance and coherency. 
 
The first mod I tried I liked so much, I decided to leave it at that. I really didn't want to mess with dynamat because its so messy, it would be too much trouble to remove it If I didn't like the affect. So the mod I tried was to simply stuff the cups with a decent amount of fiberloft. What this did was to significantly tighten up the bass which in effect brought the mids forward. I don't really think the quantity of mids increased but more so the bass getting out of the way made them come through more. The soundstage is also deeper with the treble being a bit less splashy. The sound as a whole is more balanced and coherent. The treble seems to have a touch more sparkle with more air around the instruments. They also have a bit more clarity.
 
All of this did come with a trade off though. The bass looses a little energy, but is still just a little more than neutral. But the extension is still there. So you loose a little of the fun factor with gaining a more of a reference sound. How much fiberloft you use is up to the individual to play around with. The sound as a whole is also less grainy as well. And it's so easy to do, only takes 10 minutes tops. 
 
Happy listening!!

Well, moodryn started this thread a year ago, so hope he comes back and posts up.

I love the D600 and would like to play with the bass tightness a bit but need to figure out how to get the cups open.

Are the fleather pads removables ?

cable upgrade should be also considered and you don't need to remove anything, though it's a bit more pricey.

cable upgrade is nothing but Voodoo and is an alternative for People who also believe in flying saucers.

U are blessed with sonic indifference. Wallet is safe

I was getting tired of the highs of my DT880 and that's why I bought D600, but it was just as sibilant as the DT880, but in bad way, so I would like to tame the highs a little bit.

try covering the driver with some felt

Does anyone yet know how to get at the drivers/cups for some Dynamat testing?  I'm reluctant to do anything without some prior knowledge.
 
Anyone ever had the pads off or cups open?

There's a picture of them dissassembled on this site somewhere, looks to me, like you need to remove the Denon badge from both cups.

Hi Moodyrn, how do the Denon-D600 sound compared to the Stax SR-Lambda Signature?

perhaps you are right, if you use combination of mp3 and built in laptop audiocard as a source
