Prep,
 
correct me if I'm wrong but you did not do the fuzzor mod right?

  Hi all,  
  
I took off the grilles of my HE-6 and pulled out the cotton stuffing behind them and put the grilles back on. It's hard to compare it side by side with stock as it's quite a process to put the cotton back in, but I think it could be an improvement - or at least different.   
  
Does anyone know if there's any potential negative effect of doing this? It seems like a pretty common "mod," but I'm also guessing the stock HE-6 has the cotton there for some reason. 

I asked HiFiMan, but never got an answer. To me it opens up the sound and adds some treble. The reduced treble could be the reason for the fibres and foam to be put there.
 
To me, removing the fibres and foam on the outside of the driver mostly (if not only) makes sense in combination with the "fuzzor" mod, because this tones down the high end a bit.

Yes - the fuzz or mod is done.

There are definitely some differences right, with and without cotton. If you opt on removing the cotton with the grills on, then better mids but no soundstage difference.
 
For my experience
 
Remove cotton + stock grills = Better mids and treble energy…..but no improvement in soundstage
Remove cotton + open grills = Better soundstage mids and treble energy ……….but makes HE-6 a little thin sounding
Remove cotton + open grills + foz mod / j$ pads = Better soundstage mids and treble energy………….foz mod resolves thin sounding
 
together these mods makes HE-6 lively, dynamic, smoother without losing its transparency and HE-6 delightful mids
 
also It would be interesting to try adding cotton back while other mods are on, I did not try.

Ah, you were at the head-fi meet in Annandale!  
  
Thanks for the information. I may also consider doing the "fuzzor" mod described here: http://www.head-fi.org/t/692494/hifiman-fuzzor-mod-driver-backwave-felt-damping-modification

Yes, I was the guy with HE-6 and Krell-400xi. hope you liked them

Agree on the open soundstage and energy. It gets the job done. But no such thing as thin on either of Theta Gen V + HE-9, EC 2A3MK4, Moon 430HA or class A speaker amp. I chose to use the horrible dust magnet velour pads, for the sound quality.
 
The stock HD800s on any of this, yeah that's thinner sounding than I would like.
 
Any mods that would further open up the sound and add clarity to the HE-6s, I'm all for it. No thinness or sharpness or anything undue with treble at all whatsoever here.

I liked your setup a lot. I know its much less exotic than a Krell, but I was hoping you liked my Crown D-75A, too. I've been listening to a lot of Infected Mushroom, actually, since hearing that track "Noise Maker" on your setup.

Infected Mushroom is really good. I like their earlier albums better though. Before start using speaker amp HE-6 for me does an adequate job playing those. Now every track of IM just makes me keep bobbing my head.

Does anyone have the he560 as well as the he6? It's been a long time since I heard them do audio memory is bad at this point. I'm seriously considering getting the he6 again.

Woukd I be right if the big difference is that the he6 has deeper bass and smoother mids? I know my amp is not adequate but looking at a v281 in the next few months.
