I'm interesting, can new Onkyo receivers with HDMI 1.3 accept and decode DSD from SACD....?
http://www.mm-news.org/72-new-onkyo-av-receivers-tx-sr806-and-tx-sr706.html
"The TX-SR806 and TX-SR706 have five and four HDMI 1.3a repeater inputs respectively to allow optimal HD audio and video performance with the full spectrum of Blu-ray, cable, game, and satellite sources".
If it's any help, I have the Onkyo TX-SR705 AV receiver and DSD would first have to be converted to PCM through HDMI 1.3. However, in the Analog 5.1 channel mode, DSD is passed in PURE AUDIO Form. All new receivers in order to accomodate Dolby True HD and DTS Master Audio, are in essence, a DVD-A codec utilizing the principles of Meridian Lossless Packing. For the money, however, the Onkyos are amazing and work flawlessly!

According to the FAQ (you're right, it ought to be updated) the 805 supports DSD via HDMI so I'd guess the successor 806 model supports it too, though you can't always rely on such logic. Not sure about the 706.

What do you mean? DSD is supported by HDMI v1.2 and up (see http://www.hdmi.org/learningcenter/faq.aspx#12). So DSD doesn't need to be converted to PCM by the player for transport to the receiver. You mean the receiver converts it when you feed it DSD?

Now DSD may be pretty close to analog but it's still a digital signal so this doesn't make much sense to me either. Please explain.

And perhaps a corollary question – is there any perceivable difference in sound quality in passing the digital signal to the receiver via HDMI and having it decode, vs. having the player decode and passing via six analog cables? I would suspect it would depend on the capabilities of each piece of hardware relative to the other, but can it be stated where it is generally better to decode? Put another way, apart from the convenience, and perhaps cost savings of using one HDMI vs. six analog cables, are there any other advantages or disadvantages to using one vs. the other? For reference purposes, I’m using an Oppo 980H and a Denon 2807, patched via HDMI.

Yes, generally speaking, whichever has the best DACs, and peripheralcircuitry, will give the best sound. In other words, if your receiver has better DACs and sound circuitry, then you're better off using HDMI, otherwise, use analogue. Of course, there is the added element of DSD to PCM conversion along the line.

Its not the sound quality issue, but matter of settings and applied digital post-processing...
