Here is a review of the Lexicon BD 30 BluRay player, where the reviewer does a very good job of explaining why this is a Oppo BD 83 with a fancy faceplate.
This is a case of one American producer of high end products licensing a product of another American producer and then selling the same with a 600% markup which covers the branding cost and the cost of a good looking hefty case.
This is common practice in the audio industry. You can not expect every company to have R&D team capable of working on CD Players, DVD Players, BluRay Players, AV Receivers, Integrated Amps, Speakers, etc. But you will find that most companies sell an entire range of audio gear.
There are quite a few big manufacturers of white labeled products. These companies would typically specialize in a few products. Their R&D teams would create a range of products that are then offered to other companies for sale using their own brand. A lot of time the company that puts a brand on such a product does make changes to the original product and its quality. Mostly this is limited to the changes in menu structure and some firmware tweaks along with the external appearance.
Those who believe that chinese manufacturers are only capable of copying products that they manufacture for major global brands should get a reality check. Today in the field of electronics and computer hardware, there are a lot of chinese companies which do a very good job of designing products from scratch. And there are quite a few chinese manufacturers who do offer white labeled OEM products that any manufacturer can pick up and sell with minor tweaks.
Currently there is Convergence Asia fair being held in Pragati Maidan, Delhi. I have not been to this fair in the past 2 years, but before that I saw lots of chinese cell phone OEMs offering cheap white labeled GSM cell phones. Today you see those products and their successors being sold in the Indian market by all the new "Indian" GSM phone manufacturers. I would suggest those who doubt the chinese producers capablities to visit this fair and check out the various high end products on display.
Having seen the quality of work produced by the chinese, I would not be surprised if there are some genuinely good designers working on high end audio products in China.
