I'm not being coy about details, I just don't have details yet (including any firm info on price). As more information comes in, I'll share what I can.

 

Thank You!

Whatever happened to the practice of hiring pretty models for trade shows?  Just saying...

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.

I find it distasteful

Just don't hold your breath waiting.  Audeze showed off their closed prototype at CanJam 2012, and introduced their release product at CanJam 2013.  I tend to think Audeze was far more open with their info and sharing with guests, which leads me to believe they were closer to a release produce, then Oppo currently is....

 

I think they should do things the other way. Release the headphones, then take them to CanJam a year later :veryevil:

Thanks for a ballpark estimate that I can use in preplanning, in case the medium-impedance headphone showdown for my Asus® CM1630-06 has no winner.  As I understand things, Magnepan® uses a push-pull magnet configuration for the Magneplanar® family of large open-back speakers, so the Oppo® preliminary physical layout is not without precedent.  The actual frequency response characteristics are the big unknown with this model, as Oppo® obviously intends to execute some serious engineering on the PM-1 before it's available in enough quantity for the trade-show circuit.

Thanks Jude..... I hope our peppering Oppo won't force a premature release:wink:

Only the midrange panels and tweeters of the largest Maggies are 'push/pull' with magnets on both sides of the membrane. All the rest of the panels in their speakers are 'push' only.

I own a pair of maggies similar to the 1.7 which was push only the tension on the stretched plastic membrane pulls itself back to the resting state.

Not sure if this has been mentioned on this thread but I don't recall seeing it but it looks like OPPO are actually working on a Headphone Amp/DAC/PRE as well, which will certainly be an interesting proposition,based around the Sabre 9018 DAC, they are saying that it will even drive the HE-6's, the the only drawback being that they are not actually sure whether it will make production, I have a feeling it will though.

 

More info here, certainly looks like a beast -
