For anyone that might be interested, I posted my full, lengthy review of the PM-2 at HF finally: http://www.head-fi.org/products/oppo-pm-2/reviews/11555

The info itself isn't new...maybe a couple things here and there, such as the brief ZMFxVibro comparison and measurements (full review of that coming here soon). It's just more fleshed out and better compiled and organized than what I've posted so far.

Been patiently waiting for your review Hans. Going to head over to HF and read it now. 

edit: just read the review Hans.  Very detailed and helpful. Thanks.

Got the PM-2s. Not bad at all actually. Sort of closed sounding but IMO actually a little better than the PM-1s. They are close though.

So here are some measures of the PM-2s.

Frequency Response



Distortion Right



Distortion Left



CSD Right



CSD Left

Impedance PM-2:



Comparo with Sachu's PM-1s (right driver)

PM-1 yellow, PM-2 red.



Distortion PM-1 (right)



Distortion PM-2 (right)



Perhaps a little more distortion on the PM-1, but seems to be around the same frequency area.

Awesome, UB!  :)p7

Looks like the PM-2 is a little cleaner in the distortion department while the PM-1 is a little cleaner in the CSD department. Clearly you are spending a lot of money for the extra leather and metal accents.

Did you use the PM-1 pads for these measurements?

Dunno. They had some leathery pads with little holes on the sides... They are off to Colgin.

They are the alternate pads.  Not sure if TP was involved or not.

Thanks for sending along, Ultrabike. I should receive early next week. I don't have measuring equipment but will post my subjective impressions after I have had time to give them a good listen.

UB, you sure you're getting a good seal on these (or maybe it's comp curve related)? I know the PM-1/2 aren't too dependent on seal, but they will have a bass roll-off like that if they have enough leakage.

I think this has come up before with a particular set of modified PM-1s.

I would interpret these measurements relative to other similarly measured cans. They are not IMO absolute. But yes, I think the HD600s might have a little more bass. These are not bass lite IMO though.
