3.2 sounds like it wraps around the rest of the damping...

 

Or picture would be pretty nice too >_<

pictures are worth a thousand words. :) Luckily our pal Sachu has been buying up the last few YH/HP1's and this pair was pristine ( best condition I have seen yet ) 

 

 

#1 - spare bit of foam or anything that flattens which will damp the pivot joint. 

 

 

#2 - fairly dense felt cut to about the same size as the opening, when pressed down it should overlap the sides and damp the vents 

 

 

#3 - creatology foam cut to fit the inner aspect , press fit into the cup 

 

 

#4 - gasket "stuff" blu tak, bitumen etc , whatever you want to use to seal the driver to the front baffle, roll it into a long snake and press fit the driver into position. 

 

Make sure the driver is aligned so that the tabs do not catch on the lower screws and so that the strain relief is aligned correctly. 

 

Finally close it up - I start with the screws at the wire entry and then go to the opposite side - there will be a small gap 

 

 

the gap should be no more than this - it is a firm press fit to close, and it will close smoothly and completely. 

 

 

 

This mod will not be for everyone but it is the best performance I have ever had out of a YH1 / HP1 - as good as a well modded YH100 ( which is a bear to mod correctly ) 

 

 

hope that is clearer now than before.

Great Sony transplant there.

 

and dBel never seen that thin foam used on top against the driver, seems like it works well though!

 

I've always chucked that adhesive-backed version of that exact foam directly into rears without mush success as an extra bit of added damping, then hit up the felties on the driver itself. very interesting thanks.

 I assume it adds to the top end  and a bit of sub bass?

Have you tried punching holes in it at all in various sizes or locations?

Loud and clear, and thank you sincerely for posting these pictures!

Gotta try this out when I get home.

I'd be interested in your thoughts. The felt layer dictates how much of the midrange is pulled in, the more dense the further back the mids are in the presentation. start with something that is reasonably dense but not extreme. ( moorbrook is too dense if that makes sense to you ) 

 

@ nick. Not tried punching holes in the creatology , it does exactly as you say but also seems to smooth it all out. I have always felt that you can improve on the stock HP1 marginally , but this is a different league.

Thanks. Sadly the memory foam i had was simply too fat for the cavity and it needs to be used in conjunction with one or two other things to pull it's magic.

 

Will try to make it by and grab some of the foam but non-adhesive. Got the thicker stuff but not this thin.

 

So judging by the pics there, the felt damps the side vents at the lower parts, then the foam damps the top half of the venting? The way it is laid out in the pics anyhow.

 

Has there been trials with the felt as it is but larger so it rides up the sides more and the foam secures it in? That little difference could change things somehow. Especially if everything was very precisely snug

 

Anyhow thanks .

If the moorbrook is too dense, then you guys might want to try Nick's 'Arctic Bamboo' felt which doesn't do much damping but should be appropriate here . Also, you guys might want to try some thin chamois instead of felt.

A disc of loosely-knit wool fabric between the front baffle and the front of the driver (i.e. between the driver and the baffle grille facing the ear) works well for my HP-50S - a slight increase to the soundstage, kills a few treble spikes, and hurries the decay giving a more responsive sound. At the back of the driver, I use a disc of dual-layered nylon cloth rather than felt. It took a lot of effort to make the HP-50 sound good, may be the same with your HP-3.

thank you dear saint, it really clears up a thing or two.

How's your supply of that, I'm just a PM away if you need more. wink_face.gif

Is that a closed-cell foam?
post #21761 of 23454

Can somebody comment on how David Clark gel ear seals might work with Fostex T50RPs? Has anyone tried it? 

post #21762 of 23454

Something else arrived today, the dynamic next of kin to the Russian TDS-16, though both models of the TDS-16 were  Echo and this TDS-17 is Amfiton.

 

I got these to do a recable on some TDS-16, someone used some massive wiring that was a real pain to place into a REAN TRS jack, it ended up too short. Since these have always intriugued me and the cable is identical including plug and strain reliefs to the Amfiton TDS-15's ( at least the models with the concentric squares logo not the scrolly figure "A" logo ) this will have to do for the Echo TDS-16 recable.

 

At least it is the military grade copper for what that's worth, and of same time period. Why not. The plug end is odd seems stereo but the spacer looks metal there, will find out when i open them up and i should test that soon. Worst case there the plug end simply needs replacing with a fancy right angle black Neutrik one

 

Have to say though upon initial listening I sort of don't want to ruin them now.  Very high impedance the included manual says 100 ohm, I measured roughly 46 on each channel. From what I can tell sensitivity is 98 on these. Rather really decent sounding. I wonder what they would be like with some smaller HT-21 pads and a tiny baffle mod.

 

So that's why i posted the pictures here in case anyone wants a cheapo recable to take theirs back to stock on one of their Amfitons.

Give me these over a Grado any day.wink_face.gif

 

Hmmm what to do... I know order another one!

 

 

 

DAVID CLARK PADS:there's been some posts using the Beyer gel pads ( round ), you'd have to search. White with a clear top.

 

The David Clark ones will need to be flush mounted I don't think there's a flap around the edges to hold them on, which would mean scraping off the stock baffle felt that is adhered to the face of the baffles so the bond is perfect.

 

Surprisingly they have nearly the same inner opening dimensions as the stock pads!

 

Here is one of the Air Pillow types from a David Clark headset, grungy since they are a possible project not cleaned up yet.

I assume they would be similar to the gels in size though no idea for sure %100.

Side by side and overlaid for comparison.

What are you paying for those Dave Clark pads? I seem to recall his stuff being overly pricey.

thank you soo much for the pictures nick. i looked around everywhere for the beyer gel pads but they aren't available anywhere. WHY did they have to stop manufacturing these!! angry_face.gifNow ill have to figure out a way to make the DC pads fit. They should provide more seal than the shure 840 pads, right?

post #21765 of 23454

Funny enough there is a post on the Beyerdynamic Gel pads near the top of the first full sized page and they mentioned  B&H, so I looked and what do you know beerchug.gif

 

http://www.head-fi.org/t/668341/bayerdynamic-clear-gel-pads#post_9532211

 

buy them here. says back-ordered but hopefully they will get some

http://www.bhphotovideo.com/c/search?Ntt=beyerdynamic+gel&N=0&InitialSearch=yes&sts=ma&Top+Nav-Search=

 

I would think that they would have a better seal than Shure pads, though probably heat buildup will make them sweaty at times or if using for long periods. No big deal though just take a break here and there.

Sennheiser also has some Gel pads Will take pictures tomorrow for that.http://www.mypilotstore.com/mypilotstore/sep/2425

 

 

and a pile of other things no idea about dimensions though.http://www.mypilotstore.com/mypilotstore/tag/ear%20seals

 

Hutnicks were you asking me about David Clark pads? If so these air pillow versions are not worth using on much, and they were from a free headset.
