I'll take them off your hands
TBH, I don't think the clay you used has a high enough damping factor...try to source something >0.3 on this page: http://qualia.webs.com/dampingfactorvalues.htm
blutack 0.104
"Newplast" 0.398
using the very same phone and all, going blutack(synthetic rubber)>newplast made a drastic change for me...far les resonances and stray back wave tones. A proper clay is as important as a matching disc of foam before the driver IME. This phone is like a big puzzle, the goal is to find pieces that "fit" each other soundwise.

Anyone got a source for that newplast in the US? Every place I found so far is in the UK and its pretty heavy so they have plenty of shipping surcharges for that too, in addition to the already expensive international shipping.
And speaking of mass damping the baffles of a T50RP I wasn't sure whether to dimple the surface with a screwdriver the way everyone has been doing or not. Will this really help to diffuse the sound waves that are reflected off the surface or simply mess them up and add distortion to whatever is reflected off that surface? Would it be better to have a smooth surface? My acoustic knowledge is shaky at best but I can see arguments both ways.
Nichken, that is quite a storke of creativity. Looks real nice and comfy too.
And since you bring up the T20V2s, the search tool hasn't been updated the past few months is seems...i just received two sets of the T20V2s. Anyone want to run by the T20V2 mods for me please?
I'm beginning to think that vintage orthos aren't for me. No matter what I do they are pretty harsh in the upper midrange. I've only heard Fostex and Yamaha, so maybe they exhibit this and others don't? But I went so far as to cover the majority of the front of the YH3 with micropore, and dampened them with nothing but some fairly open cell foam and this actually brings the most neutral and balanced sound I have heard out of them, but they're still harsh. Anything I do with felts just makes it worse. I guess I always heard this, but since I thought the whole point of orthos was to avoid the peaky response of dynamics, I always just thought it was a damping issue. I also hear such potential in all of them. For comparison, all of my dynamics have smoother upper midrange and treble while having more treble presence. And phones like the M50, HD600 and K340 are not warm or rolled off. It seems strange because most of you don't seem to have this problem, and it seems that most of you also like the LCD-2 so it doesn't seem like our tastes are that far off.
oh, and nice work Nikchen! Looks great.
