question: I presume you're interested in test point access so you can do a little I2S tapping?
BTW, if you're not specifically focused on I2S; but are looking to access the 983's Mediatek processor digital output for use with your own DAC of choice: you can access the PCM via HDMI.
As with the 980H, Oppo has confirmed that the 983H outputs the following via HDMI:
CD @ 16/44.1
hardware-decoded HDCD @ 20/44.1 (thank you Oppo!)
DSD converted to PCM @ 24/88.2
DVD-A up to 24/192
I've been enjoying 20/44.1 hardware-decoded HDCD from my 980H to my DAC-o-the-moment and computer audio interface...... now just waiting for high-quality DACs with HDMI interfaces to make it somewhat less convoluted than the current hardware solution.
Yes, I am interested in the I2S points to output out to my DAC. In particular I want to have true digital out of the SACD audio I am currently looking at the oppo 981 for this purpose, but if the 983 can do it too, I will definitely pick it up.
What are you using to process/access the PCM stream inside the HDMI? The licensing fees for HDMI have been rather cost-prohibitive

1/ DSD, Oppo have confirmed that the 983H unfortunately does not provide the DSD stream over HDMI, only the 24/88.2 PCM downsampled version.
2/ PCM stream:
Oppo HDMI > Atlona AT-HDMI-DVI ---> vid out: DVI ---> video destination
Oppo HDMI > Atlona AT-HDMI-DVI ---> aud out: SPDIF coax ---> audio destination
several options wrt the HDCP-compliant video destination: HDCP-compliant HDTV's DVI input; HDfury > PC monitor; others. Of course you must have the video destination powered on.
This works w/ 24/192; if you only want up to 24/96, gefen makes some HDMI-DVI converter products (audio: TOS and IIRC coax outputs on various products). However, as of a short time ago, gefen steadfastly refused to confirm if their products will correctly pass 24/192. I even had time with a VP and he came back only with an "official" response that they "meet SPDIF spec..." Perhaps this was simply putting a stoic face on time until they are 24/192-confirmed....
Another option is a receiver with HDCP-compliant HDMI input which provides a dig out; I didn't investigate this path as my interest was to use my own choice of downstream audio equipment. However, IIRC I've seen postings that such creatures exist, think they were very high-end / pricey.
oppo---> some device ---> benchmark dac (in on rca or toslink) for 24/96 capability off of dvd/dvda/dad (or sacd)?
You may have difficulty doing this... Even if you sent the high-res signal from the DVD player to a receiver over HDMI, the receiver might still restrict the unmodified output from being transferred (ex. via a digital output on the reciever).
AFAIK, there are no consumer external DACs that can decode a DSD stream, so the DAC1 can't be used with SACDs.
However, there is a somewhat unique route. A few Panasonic DVD players came to market without the copy-protection-based downsampling that's supposed to be implemented. They will output the unmodified stream over both coaxial and optical digital outputs, all the way up to 24-bit/192 kHz (IIRC). There's a thread around here with model numbers if you're willing to search.
what's the point of the USB? anyone? I mean how do you use it (rather than speculate what one might use it for)?
Plug in a USB storage device that has videos in either AVI (DivX or XviD) or MPG (MPEG4) format, or audio files in WMA, WAV, or MP3 format, and the Oppo will display a menu that allows you to sort through them and play them back.

from a quick search it seems panasonic only does this for unencrypted discs?
I got kind of excited thinking this was a blu-ray. What is $200 better about this than my 980H?
It contains the superior ABT Chipset which if you plan to upscale your image on a Hi-def screen will justify the extra $200.00. Trying to get this performance from a Japanese or European player would cost you an arm and a leg. Also Oppo provide considerable support to their products.
