Got it Red. Either way, the Oppo really is a great SACD player in addition to everything else. Whether PCM or dsd, all good. Were all trying to squeeze every last drop of performance out of it. I'm experimenting with isolation and at the risk of ridicule, can say there's a worthwhile tweak there too. But now I'm really going off topic.

Loopinfool.. The dsd is on the m/ch outputs also. Not just stereo. Sorry, I wasn't completely clear. I meant to say the 83 has a special DAC that can directly convert DSD to analog, but it's only stereo and has separate RCA outputs. The Multi-channel outs on the 83 and all analog outs on the 80 will get converted to PCM and sent to the multi-channel DAC on the unit. I'd expect the sound quality to be similar between the Oppo's analog output and the UMC-1 via PCM in this case. - LoopinFool |

It is converted to PCM before it is output via analog as the DAC does not support it. This explains the separate DAC on the BDP-83 you mentioned. 2) The player will automatically switch to PCM if DSD is not supported on the pre-pro/AVR. PCM in all cases is 24 bit/88.2 kHz. This explains why I am hearing a difference with the SACD versions of same CD titles that I own, but not hearing any differences between analog or HDMI since it's all being converted to PCM 24 bit/88.2 kHz. I otherwise took the below statement from the BDP-80 manual that DSD-to-analog was supported, which I checked on before buying the BDP-80. It's apparent this just means it will play audio from an SACD over analog, just not full SACD resolution. No problem with me since I'm planning a purchase of the hot-rodded BDP-83, and I use the BDP-80 mostly as a blu-ray player in the second setup anyway. |

I just saw that on the comparison chart. The 83 does do DSD to the m/ch analog however.. not just the stereo outputs. Oppo doesn't mention that dsd is only for stereo analog anywhere and the reviews I've read have said the m/ch analog do have that capacity. The 983 also would go dsd to m/ch analog from what I've read. Although I prefer the stereo outputs, occasionally I'll use the m/ch and if the display is turned on during playback, song starts over in pcm and sounds obviously different though close.
If you're getting the 83SE, you'll be very happy! Well worth it to me.

However, the DSD data will be converted to PCM before it's converted to analog, just like if you sent PCM to the UMC-1 via HDMI. Notice in their comparison chart ( www.oppodigital.com/blu-ray-bdp-80/blu-ray-BDP-80-Compare.aspx) that the "SACD output over Analog" line shows DSD/PCM for the 83, and just PCM for the 80. The DSD exception on the 83 is 2-channel DSD sent out the extra dedicated stereo analog output. Those have a separate DAC that can convert DSD directly to analog. - LoopinFool |

No, the comparison chart makes no distinction between stereo and m/ch. It means you can select either pcm or dsd. It's been discussed at length at avs with the apparent spokesman confirming dsd to all analog outputs. I stand corrected. I was repeating something I read elsewhere (in a discussion of the BDP-80), which was obviously wrong about the BDP-83. - LoopinFool |
