If you were to buy a PM-2, then attach your choice of PM-1 pads, plus the PM-1 cable, you'd be left with frame and headband differences that could have no impact on sound quality any moreso than the wood presentation box, the denim carrying case, etc. 

 

VEEEEEERY interesting !

 

On the one hand, doing this approach would make one worry about the "halo effect." Testers KNOW that the cans on their head, or at least the drivers and the immaculate finish, are the PM-1s, and that could color their judgement.

 

On the other hand, if the internal working parts are identical, then the null hypothesis for testing (so to speak) *should* be that the PM-2 sounds exactly like the PM-1, unless the cables and ear pads make an audible difference. 

 

If the general consensus agrees with this:

then the soon-to-arrive PM-2 is going to cannabalize the heck out of PM-1 sales, long before they would normally crest.

 

Since Oppo has to know this, clearly the PM-2 is being positioned as the world beater. And while the PM-1 is priced above the new HE-560s, the PM-2 would have a price advantage. Gonna be interesting. Exciting times to be a headphone addict. (Sorry about our wallets.)

Those of us who are beta testing the PM-2 were told no new NDA was necessary.  Given that both the PM-1 and HA-1 NDAs have been lifted, I'm not currently under an NDA. So, I'm free to answer your question.  :smile:

I was operating with the assumption that they had another NDA over your head; I would've been badgering you for more impressions via PM throughout last month otherwise! Your impressions spell great news for me; I won't have to shell out for the PM-1 when the PM-2 hits the (online) shelves.

I ran the PM-1s out of the same DAC into several very different powered amps and found some, but very little, scale at very high volume and very high power.  I think these will work fine from whatever source you have, low end desktop or phone dac or whatever.  I am still planning on testing with balanced cables though, maybe magic will occur.

Has anybody had a chance to compare the B&W P7 to the Oppo pm1 while using the iPhone 5S and the Onkyo HF Player app while playing flac, 24-96,192, dsd music files?

In the last five months since I received the P7s I have been using it more than my HD800 and my HDVD800 amp/dac.

 

I find the B&W P7 to be outstanding all around headphone and the bonus is it sounds terrific as a portable device.

 

I'm just wondering how the PM-1s compares in sound quality or mostly its improvements over the P7s.

Feedback from owners of both headphones will be greatly appreciated.

Thanks

Praying that everything works out well for you.  Be strong.  Hey OPPO guy,  how about getting "cute" a spare set of ear pads.  Please.

Since cupping your hands over grills on the pm-1 make no discernible difference, I propose interchangeable open and closed grills. :L3000:  I kid of course.

It is a great idea. I like it.

Just do what Audeze does, and name the closed version "PM-1C", with fully-sealing leather earpads too. Shake the closed headphone category upside down.

Hey, anyone noticed the little bump on the LEFT swivel assembly?   Where the left ear cup attaches to the headband assembly?    Left ear cup indicator!   Nice!   I know, Sennheiser has three bumps there but it shows how well thought out this new design really is.   

Just a little Oppo news for your early saturday morning coffee.    :tongue:

I like the idea. The PM-1 is super with the AK240 . If you make a close version  it would be an all the tome system with the AK240

Hadn't noticed, thanks.  Small but very useful feature.

That's smart design. :D

 

I wish that whole left side where the dot is were brushed aluminum like the cup frame. It's prone to finger prints and doesn't quite look right IMO.

Geeesh, I never noticed that, thanks!  I always had to put my glasses on and turn on a light to see the L vs R!

The bump appeared as seen in the retail version, with the second prototype we received from OPPO (the bump is on the outside of the bracket):

 

 

This is the first prototype we received from OPPO (the bump was on the inside of the left bracket) - open the photo in a new tab or window to see a larger version:

 

 

Another example of improvements made during beta testing...

To be honest, we anticipated releasing replacement pads and cables as maintenance options, so we did not prepare to have these available for sale immediately as we were anticipating months of use before customers would require replacement parts and accessories.

 

If you need extra velour pads now, rather than later, you can call during our standard business hours (Monday through Friday from 9:00AM to 5:30PM PST) or E-Mail us and we can arrange you replacement velour pads to be sent to you. We have a very small quantity of "emergency" replacement pads which we can make available to you.
