Yeah, I was, but pretty much ignored most of those threads/posts due to the overbearing emotional content. I take it those threads beat this one out by a long shot?

Wonder if this one sets a record for a hardware related thread?

Have an Onkyo 805 receiver and having trouble setting up Audyssey?

Looking at the posted photo, on the board I think I see traces running to all of the DSD inputs of the multichannel DAC, but I can't trace them back to discrete input pins on the connector from the main board.

Ah well... was hoping they'd change their stance on who they'd send out units to. Luckily I have a fair amount of patience. I can hold out til the official release.

No, selection is based off of your location on the Blu-ray Interest List. They may weed out incompatible applicants due to e-mail address, country code, IP address or other means before actually running the numbers through Random.org.

Looking at photos and determining what it can and can't do is not verifiable proof. Unless he has tried to perform a mod, or used the player and can replicate a sequence which shows a DSD to PCM conversion has occurred over analog, there is no proof.

Until someone can direct proof bu using the actual product, there will be no alteration of the First Post.

It would mean that the player always converts DSD to PCM over the analog outputs. That is, there is no native SACD DSD streaming over the analog outputs.

So it appears that if your setup meets the qualification's noted, you can defeat the menu click sounds.

Nope. The disc over-rides those settings if you are using LPCM audio over HDMI.

In defense of the button sounds, with how slow the first generation players were in response to button commands (both red and blue), button sounds were an absolute necessity to prevent machine lockups and unintended responses to multiple button pushes.

Is this what is in dispute?
(From the BDP-83 manual)
DSD – SACD DSD data is output over HDMI without any conversion. For the analog audio
outputs, DSD data is converted into analog signal directly by the internal DAC. If you use a receiver that supports HDMI v1.2a with DSD over HDMI, or you prefer the sound quality of straight DSD to analog, please select this option.

Yes, someone claims to have looked at the actual circuit board and determined that the manual is wrong as regards DSD -> Analog without any intermediate conversion to LPCM.

Looking at the posted photo, on the board I think I see traces running to all of the DSD inputs of the multichannel DAC, but I can't trace them back to discrete input pins on the connector from the main board.

On the CS4382 for PCM Audio for 8 channels you have

Master Clock Pin 6
L/R Clock on pin 7
SDIN1 Pin 8 (PCM serial data for 2 channels)
SDIN2 Pin 11 (PCM serial data for 2 channels)
SDIN3 Pin 13 (PCM serial data for 2 channels)
SDIN4 Pin 4 (PCM serial data for 2 channels)
Bit Clock Pin 9


For DSD at the DAC you have
DSD-Serial Clock Pin 42
DSDA1 Pin3 (DSD serial data 1 channel)
DSDB1 Pin2 (DSD serial data 1 channel)
DSDA2 Pin1 (DSD serial data 1 channel)
DSDB2 Pin48 (DSD serial data 1 channel)
DSDA3 Pin47 (DSD serial data 1 channel)
DSDB3 Pin46 (DSD serial data 1 channel)
DSDA4 Pin45 (DSD serial data 1 channel)
DSDB4 Pin44 (DSD serial data 1 channel)

NOTE: The CS4382 does not share any pins between DSD and PCM input. It is 9 totally different pins into the DAC for 8 channels of DSD.

To control the CS4382 you also need two lines:

SCL Pin 15 serial control port clock
SDA Pin 16 Serial Control Data

Now look at the ribbon cable feeding the audio board.

+5v
DGND (Digital Ground)
SACLK (Master Clock)
S3CK (bit clock)
SLRCK (LR-Clock)
DGND (ground)
DATA0 (PCM Serial Data for 2 channels)
DATA1 (PCM Serial Data for 2 channels)
DATA2 (PCM Serial Data for 2 channels)
DATA3 (PCM Serial Data for 2 channels)
DGND (ground)
SDIN (PCM Serial Data for 2 channels, 2 channel downmix DAC)
DGND (ground)
SCL (Serial control port clock)
SDA (Serial control data)
DGND (ground)
DGND (ground)
DGND (ground)
DGND (ground)
RST (Reset)
????
DGND (ground)

BTW, anyone that wants to try and 'scope this... play a SACD (with HDMI set to DSD) and then look at pin 7 and Pin 42 on the CS4382.

If you see a clock on pin 7 the DAC is receiving PCM. If you see a clock on pin 42 it is receiving DSD.

If it is PCM the frequency of the clock on pin 7 is the sampling rate of the data being fed to the DAC.

I wonder whether we'll be able to get a response from any of the EE's at Oppo over the weekend?

Agreed 100%. This is on par with the remote that ships with DVDO's Edge, which is excellent. I still use a Universal remote, but the BD83 remote is the best I've seen on a Blu-ray player, and I've reviewed a lot of them.

for the record (and I know this is the subject of debate) such incredibly techy posts like this make me supremely happy... I mean, so much is just rambling back and forth, it's nice to see someone with far more Electronics experience than I show a way formally of testing assumptions rather than basing it on hunch (or a manual that's undergoing changes).

It's the upping-the-ante of the nerd level that I find amusing.

Neuro is of course right not to change the first post based on this theory, but it's undeniable that the evidence is compelling. Now, whether or not this is a deal breaker for some is certainly up for debate (being able to -hear- the difference would be up for grabs, certainly). Still, if there is an error/misreprentation, there's clearly enough from your post to at least verify with Oppo engineers just what's going on here...

yeah, worries me that Neuro had the internet when he was 18... man, I feel old... The worst thing I was doing at that age was lying in order to play Leisure Suit Larry....and that was by answering questions about the Beatles correctly!
