If these cost anywhere near a 1000.00 that would be a huge mistake for oppo imo no matter how good it sounded. As a newbie to the headphone world, you just can't price stuff the same as other products that are well established, tried and true. I know there are people here that will buy them at that price if they sound the part. But that number is small in the grand theme of things. If these debut anywhere near the 1000.00 mark, many will say for that price, I can have an lcd2 beyer t1, etc. Or better yet, for 300.00 less one could have an he500. And that's what many will do instead of spending that kind of money for something unproven.
Remember the original he-5. Many were saying it might have been the best can on the market, and there were comparisons to the hd800, and T1 everywhere. As a previous owner, I will say it easily sounded good enough to be priced at 1000.00. But it debuted at 600 and instead of people saying it was over priced, they were raving about how great of a value it was and it sold like hot cakes. Hifiman later improved on the design with the he5le and later the he6. And by the time of the he6 they were a well established company that had gone through the growing pains of earlier designs and were known for producing great orthodynamic cans. So they could easily justify charging 1300 for the he6 with many still saying they are still a great value at that price.
That's just one example of many when it comes to bring new cans on the market.
