Oppo PM-1: A New Planar Magnetic Headphone! - Page 23

post #331 of 2548

Maybe the hearers of the LCD-X are still too mesmerised by them to post about the experience.

Or, it was a non-event.....

I've been looking for one for so long for a reasonable price but have yet to find one. 

It's not the 'reasonable price' that's the biggest problem, but the actual finding. 

It doesn't even seem to pop up at head-fi meets either for auditioning purposes or bragging rights.

With the LCD-3 you have an array of 16 magnets, 8 per side, per driver as I understand this from a bit of research.



The area of the LCD-2 and the LCD-3 membrane is 6.17 square inches, which is about double the radiating area of a typical dynamic driver of 50mm diameter with 2.5mm maximum excursion available between the magnets.



You can still have some push and pull effect with magnets on one side but Magnepan used to call magnets on one side push like mine some time ago.



 



Thanks for the research. That means this push pull is nothing 'special' anymore.

The abyss is push only as I remember. As far as I know push-pull is superior to push in most instances when measuring distortion and so on..

^ oh, surprisingly for the price, but they can argue they use more powerful magnet etc etc.

No, their argument is not "stronger magnets". It is their claim that the sacrificed efficiency with single-sided magnets is dwarfed by the increased clarity due to backwaves reduction compared to having both sides lined with magnet assemblies.

Not sure what you meant by  nothing "special" about push pull.

One of the reasons I ended up getting rid of my Magneplanars or maggies as I like to call them was compression at moderate to loud volume due to nonlinear nature of the magnet strength by distance. With magnets on one side the magnet forces on the diagram comes much weaker quickly with distance as the diagram pushes away.  This makes things like piano playing at fortissimo levels losing some of its sharpness at transit peaks.

I find that electrostatic forces like on my Stax headphone sounds a bit more linear. I noticed that my Fostex T50 the sounds tend to bounce around a bit at certain frequencies.

These headphones were secret. Jude said he hid them under the table when too many people stopped by, and they wouldn't let anyone else listen to them. So pretty models would not have been appropriate.

 

They're nowhere close to production. It sounds like they will be making some major tweaks to their sound signature.

 

Pretty models are always appropriate.

I am a bit of an Oppo fan boy, having (all?) of their DVD players and many of their Blu Ray players. The 105 is just sublime. Oppo are mid range price, high end delivery. I wondered about a headphone after I saw their DAC / Amp prototype. I am another very interested in this. I expect serious permance for the money, just wish Henry was still here with us :(

Give a shout out frank I he has an oppo player he might have some inside info.

Well they are rare to begin with, I've seen around 6 or so in the past 3 years pop up on various auction domains, but none for the price I'm willing to dive in and give it a try at, it's mostly for bragging rights though as the last person who sold theres here didn't think they were that good.

I meant nothing new anymore, but no doubt it still very good. No wonder Stax sounds very good.

OPPO announced on their Facebook page that they now have a "Future Products" section of their website highlighting the headphones and amp / DAC.

 

Still no pricing information, but an interesting read nonetheless: http://www.oppodigital.com/future/

My jaw dropped when I saw the pic on the landing page. That is dead sexy.
