Got the PM-2 in and have been putting it through my normal tracks. Very early impressions (subject to change):

- Less warmth than PM-1, overall more neutral balance. Seems more in line with my HE-500, but overall more laid-back and less punchy (i.e. still a bit limpish). Good tonality.
- Marv was spot on about what he mentioned with the 8KHz peak. Not exaggerated, but gives a less pleasant, rougher sound than having one at, say, 10KHz. But it's not really a problem...just stands out a bit. I think Oppo could have and should have done a bit better here. I'm already working on basic front mods to smooth it out a bit, because stuff like this easily annoys me. (About to go to bed and am tired, which is when things like this really get to me.)
- Not nearly as constricting sounding in terms of air and soundstage. Still not a particularly open sounding headphone.
- Not the most clear across the spectrum headphones I've ever heard.
- Goddamn, this cable is microphonic. Scares me sometimes while listening.

VERY quick measurement attached. Was even too lazy to edit out the ugly window parts. Left channel, from left ear, ~90dB at 1KHz (playing 0dB signal). Full review and measurements to come in next day or two.

Whoa! I just took a look at the jergpad tutorial. That looks too complicated for me, so I guess if I wanted jergpads I'd have to contact Modulor. Still holding out hope for the Focus-A pads though. I was OK with the sound of a stock 560 out of WA7; I think that amp smoothed out the sound.

Hm yeah you're probably right, this was a mod that was 1 year in the making/development, it got so many iterations and not just from me, but a few others i.e. modulor. I've been trying to let modulor know that he may wish to buy off a last batch of pleathers/velours from Hifiman before they discontinue those pads forever, hope he acknowledges.

I'm in the process of modding the HE560, IMO jergpads are essential for the "perfect" sound I'm personally seeking, so is regrilling mod, but there are 1 or two more mods that seem promising.

Is Ryan still selling jergpads?

Here's what I got.  Please don't spread it around. I'll post something next week.

All four pads on a PM-2. Haven't done any listening yet.

I'll do an update at the end of the month. They're too spiky on the initial edge for me.

Peak move to 10k on Tyll's measurements?  Manufacturing variations or will HRTF turn that trough into a peak?

Tyll,
   apparently PM-2 has a different dampening on the back of the driver I suppose it would be nice to compare it to PM-1 with both original pads.  Based on Marv's impressions alternate pad made for PM-1 suits PM-2 best and so I wander how it fits PM-1 itself assuming it has original dampening scheme?
