Question:
I have a few SACDs that I play in my Oppo 93. If I tell the Oppo to play the SACD in CD mode I thought I could run it thru my XDA-1. But no matter what I try there is no sound. I throw in a regular CD and it plays just fine. But an SACD will not even if the Oppo is set to CD mode for SACDs. I assumed that the stereo track of hybrid SACDs would just send a digital signal out to the XDA-1 but apparently not.
Anyone have any idea if this is normal?

Geebo,
From my knoweldge SACD only supports 5.1 analogs out or HDMI. The path cannot be through Coax or Optical.
Since the XDA-1 Lacks HDMI (I've been told) then you are stuck sending it out Analog.

But Hybrid SACDs have a normal CD layer and can be played on most CD players. I just thought if the Oppo was set to CD mode (for SACDs) it would be handled like a normal CD but apparently not. Its not a problem per se, just a curiosity. |

gotcha... now my question is. Wouldn't 2 channel SA sound better going through the Oppo DAC then sending CD version of through the XDA?

I was just curious how the CD layer sounded on the Wish You Were Here SACD. The surround mix is outstanding and I wanted to compare the CD layer with the standard CD issue. |

I have found that not all SACD album have the CD layer even tho they claim to be Hybrid. Do you have a plain CD player to test this out? If it runs properly on the plain CD player I think the Oppo has a flaw in the FW. You will probably need to check with Oppo Tech Support to find out if they are designed to play the CD Layer of Hybrid SACD.

So the CD layer is there. Now the question is what does the Oppo do with it if anything. |

George, the CD layer was usually recorded with DSD bitstream, but still the standard Red Book CD.
It just sounds better than a regular CD.
And as you well know, that CD layer is fully compatible and playable in any player from both its analog and digital outputs.
If it doesn't, some's wrong!
* Did you try to play the CD layer from your Oppo 93 without the XDA-1 into the equation?
It should play, and from its analog out and from its multiple digital outputs (HDMI, Coax & Opt).
-> Just make sure that your Oppo player is set to play the CD layer of that Hybrid SACD, by the proper audio selection...
...OK, what's the verdict now?

I just sent an email to Oppo asking if the 93 actually reads the CD redbook layer when set to CD mode. |

Yes, it plays thru HDMI and analog outputs with CD mode selected. The Oppo's coax connection is only going to the XDA-1 and nothing plays when the XDA is selected. Normal CDs work great. |

George, I am sure that it will also play from its digital Coaxial & Optical outputs going straight
to your UMC-1.
Did you try? You don't have to try both, only one would be sufficient. Do you have an extra Optical cable around? ...You don't really have to, as we already know that it plays from the HDMI and also analog connections.
So, your Oppo 93 is working perfectly.
Now, what is goin' on with the XDA-1, between your Oppo player and your pre/pro, in that particular situation?
- It seems to be only from the CD layer of hybrid SACDs that you are encountering this issue, isn't it George?

...I have a good theory, but we need to find out more first George.
Best is you try the digital Optical connection first; directly to your UMC-1 pre/pro.
If it works (the Stereo CD layer of those hybrid SACDs), then we'll concentrate on the XDA-1 and what it does exactly with that audio signal...

Correct. And its not a big deal but I'm puzzled by it and I hate being puzzled. I have not connected coax or optical from the Oppo to the UMC yet. I may give that a try tomorrow night. |

OK George, take all your sweet time, and try what I asked you to try in another above post. ...That would only take a minute or two. Oh, I would like to know how the UMC-1 is handling a DSD audio bistream signal from the SACD layer of those hybrid discs, and of course directly from a digital HDMI connection. _______________________ I am almost 100 percent convinced of what is going on, but me too I will take all my sweet time to reach an inteligent and logical conclusion. ...And right here, in this very own thread.

Your thread George. The UMC does not decode DSD. It must be decoded in the player and passed as LPCM or analog. And its time for bed now but tomorrow's another day. ;D |

Yeah, I was almost sure of that. ...Meaning that your Oppo 93 has to convert the DSD audio signal and output it as PCM. ...From it's digital HDMI Out. Now we'll concentrate on the XDA-1. ...And its digital Coaxial handling from the Stereo CD layer of Hybrid SACDs. Because it has no problem at all with regular CDs, of course. ...And the UMC-1 does no have problems accepting the CD layer of them discs, DIRECTLY, through all its various analog and digital connections (well, only dig. Coax & Opt remain to be confirmed). So, we'll see very shortly, what the 'puzzle' is all about! ...Good night & sleep tight. |

I emailed Oppo on this:
To: OPPO Service
Subject: Hybrid SACD
If the 93 is set to CD mode for SACD playback, does it actually read the CD layer? And if so does it output a 2 channel pcm signal out the coax connection?
I have an Emotiva XDA-1 DAC and cannot get a hybrid SACD to play thru it no matter how I set the Oppo.
And their reply:
George,
Yes, the player will support the CD layer of hybrid SACD media. Go into Playback Setup and set your SACD Priority to CD.
The player will now output CD-Audio through digital coaxial and optical outputs.
Best Regards,
Customer Service
OPPO Digital, Inc.
So what I'm reading into this is that it should play thru the XDA-1, but it won't. Tonight I will try bypassing the XDA and go coax from the Oppo to the UMC and will also try a couple more SACDs (the only two I tried were both Pink Floyd - DSOTM and WYWH).

George, I am still waiting patiently on that last test you just mentioned above. * As for the Oppo 93, and what Oppo told you in their reply, I knew that. ______________________ I know what the 'puzzle' is all about; I'm just waiting for your latest discovery from the above last test. - My guess: YES, it will work; you will receive sound when directly connected to your UMC-1 from the digital Coaxial & Optical Outs of your Oppo 93. Only after your confirmation, that I will explain to you my theory of the highest probability. ...Demystifying the Puzzle! ;D |

I connected the Oppo via optical direct to the UMC then set the Oppo to CD mode for SACD. The 2 channel layer played fine. So I switched to the XDA-1 and it played too! Wouldn't do it last night. The Oppo reports outputting a 2 channel 44.1k stream. When using the direct connection from the Oppo to the UMC, the UMC also reports 2 channel 44.1k PCM. But when selecting the XDA-1 then the UMC reports a 2 channel analog 48k signal. But I think I just found my answer here. If I stop playing the SACD 5.1 layer, go into the Oppo setup and select CD mode, then start playing again, the Oppo goes into two channel but still reports SACD track type and will not play thru the XDA. But if I turn the Oppo completely off then back on again it will play the standard CD layer fine thru the XDA and reports track type CDDA. So it appears that turning the Oppo after switching modes is the key here. Ejecting the CD and re-inserting also works. One of the two must be done. I'm really surprised I didn't think of that earlier...  |
