Removing the foam from HD600 - Page 8

post #106 of 107

I just found out another foam mod for the HD600

 

Basically u remove the tiny piece of foam that is above the outside part of the driver!

 

See a description here:

the upper registry opens a bit.The sound of bass seems to me less congested and has a more natural sound.A little more speed on transients.
Before removing the foams on the outside of the drivers i've listened 2 times to a song i'm extreme familiar with.And i've done the comparison listening to the same song
 

Before you try this u should know though, that its hard to put the foam pieces back on.

just tried the classic foam mod incl. the outer-little-foam-mod from apuresound as well...(w/ original cable, otherwise A/Bing would be insufficient..)

 

the curtain lifts its face, sounds not so muffled/veiled as before: bass has more accuracy/defintion but loses the senn-typical (HD56x/6xx) roll off and dominance, treble is clearer, cleaner, and more realistic, same with the middle, very realistic, but even: i would tell it are the middles which are the "weak part" within this mod, not the bass...because they sound so much more lively than the rest - got it?-) everything else is just not as good as these natural middles!!

1st, i think now i can separate the instruments better, especially with complex sounds as classical works...2nd, sounds more neutral, and even reference-like, because the frequencies are somehow averaged and voices are centered more. tends to sound a fad more like a grado hp, as mentioned in this thread earlier...

 

what questions me right now, if the superb soundstage of HD600 improves or downgrades w/ this mod..? the separation is easier with the mod, but somehow the instruments are played like "apart" from each other, but closer (e.g. like in a smaller room), which is usually a good sign for reference hp's - but: OTOH i am missing the overall congested sound of the original senns which keeps the record "together" and opens this incredible room in front of me...hmm time will tell, maybe i have to adapt first...
