Orthodynamic Roundup

I find that classy sounding is a better word for it

Wow 2 weeks since the last post, did we reach some sort of technical limit?
 
I've been following this thread off and on for a long time. I remember reading the entire thing when it was about half its current size.
 
I recently acquired a pair of HP-1's and am itching to get to modding. I want to ask if there is a consensus on what the best mods are? Have been enjoying my YH-2's for a couple years now and only have vague memories of what I did. I do know it involved replacing the foam and using a felt donut to damp the driver. However, I would have to open them up again to see if I left in the reflex dot or not. That being said, I know the HP-1's may deserve  a different strategy.
 
Don't really want to go back and read through the entire thing again. And, before it comes up I have used the search function without coming up with a definitive place to start. My take is that mod paths usually evolve as more people experiment and after using the search function I am left with a lot of disparate posts, but no single guidepost.

I too am looking for information.
 
So far what I've found is that the felt-paper-felt damping configuration works best for the YH-1. It's just like it sounds; 2 circles of felt sandwiched with a circle of paper in the middle. 
 
If this is wrong or someone has something better, feel free to jump on in and correct me.
 
As far as this thread being dead for a while, guess what I found...
 

 
NOS. They're on their way right now. Excited.

If anyone needs spare ear pads for their old (over-ear 100mm size) PMB headphones, they still make the same headsets (unfortunately with dynamic drivers), and have spare parts in their store: http://www.german-maestro-shop.de/epages/61902279.sf/en_GB/?ObjectPath=/Shops/61902279/Categories/Zubeh%C3%B6r/Ohrpolster

That's nice 

 
Pictures of the inside later? Perhaps an entry in the wikiphonia?

Thanks for the stock GMP/PMB pad link I never thought of that. Even looks like the old catalog pads right down to the scrunchy edges.

Their new headsets are just about identical too - same cups, headbands, they even have the same red/black cables.

DIY Replica/ prototype maybe hmmmm....

Rather tempting, to take an old PMB driver... (I suppose some of the old USSR drivers and Yamaha drivers would fit as well...)

 

[nick n]

Wonder what a new T50 driver would be like in there.
 But in the interests of keeping costs low an older round thing would be perfect if it was on the bassy side, some of those old PMB are lighter sounding aren't they...

 

[DefectiveAudioComponent]

No, if you repair them properly, they are not bass light. This is an unfortunate reputation they have got from people who have tried them with ruined ear pads.

But of course.

Considering most of the stock pads go to fabric by the time folks here get to them, that's a great point I never thought of. Had always assumed folks would fix the pads before anything but that's my thinking not everyone else's. This would include much of B&O U70 impressions also ( housing issues aside ). Only bass light ones I can recall that are similar are the Hok's, but are they %100 an actual PMB driver not sure/ do not recall.

Regarding the U70, I didn't find they were so much bass light, it was moreso that they sounded really hot and unnatural throughout the frequency range... it was basically just like my (heavily modified) KOSS Pro/4AAA tonally, with somehow worse transients and higher THD. Compared to my (stock) YH-1, they were damn terrible. They just sort of seemed to sound "off" in some way that I couldn't really describe at the time. 
 
It's weird, since the Magnat RT-10 (menitoned earlier) uses the exact same drivers but somehow manages to be quite nice sounding, at least according to DAC...
 
Which prompted me to start experimenting. I'm working on transplanting them into an Audio Technica ATH-6 shell right now. Here's a WIP shot:
 

 

 
Cheers.

ohh yeah very nice work, and that shell is tops. Keep the updates coming.
