I recently reread most of this thread, it appears the consensus is that if you can, go straight out of the OPPO HDMI 1 into the TV, then go analog out for the SACD/ DVD-Audio playback, straight into the Amp then into the speakers. By doing this, is the movie soundtracks audio also going to be from the analog out, not the HDMI? Is this ok for some of the newer sound processing like DTS HD Master Audio?
If I ran the analog from the OPPO into the Onkyo TXNR-809 AVR analog multichannel inputs would this be a degradation of the sound? So I take it, that this is not a analog passthrough once it goes into the receiver? The AV receiver has 192KHZ/24 bit (PCM 1690) all channels TI Burr-Brown DACS, but I assume that the OPPO is a much better DAC and you don't want multiple conversions?
When going analog out, how do you see the DVD-Audio menus and lyric screens on the TV? Do you see it from the video portion of the HDMI since it is a AV Split?
Going straight out of the OPPO into an amp and running my Direct TV into the OPPO from the HDMI input in the back is intriguing. The only drawback I have from not using my current receiver beside additional costs for a new Amp is that I have a turntable connected to it, plus sound is also run to my bedroom, and outside porch through Multi-zone, oh well, the sacrifices of trying to improve ones audio. The other concern is the lip sync issue I am experiencing playing Blu-ray's on the OPPO, if I run the Direct TV through the OPPO, will it have the sync issue too?
Thanks again for your answers. .....Mark
OK, several different topics here.
The multi-channel Analog outputs of the 105 are capable of playing every file format the player can handle -- both music and movies -- at top quality. The same is true when playing stereo content using the Dedicated Stereo Analog outputs -- whether that's stereo music content of movie content. (Playing multi-channel content out the stereo outputs would, of course, require a "down mix".)
Next, your Onkyo may very well provide a setting for analog direct "pass through". In which case it is basically being used as a pre-amp -- just volume control. Doing that means you forego any value-added audio processing in the Onkyo, such as Audyssey room correction. Any such processing would be done digitally, and thus the analog audio input would have to be re-digitized by the Onkyo as the first step, then processed, then converted back to analog for output using the DACs in the Onkyo -- hardly a case of "pass through".
HOWEVER, you may LIKE the results of Audyssey (or other processing in the Onkyo) enough that it still SOUNDS BETTER to let the Onkyo do all that for you. Personally I always pass Analog audio through my Anthem Statement D2v and let Anthem Room Correction (ARC) do its thing. It's amazing.
The folks experimenting with the direct-to-power-amps analog connections are going a step FURTHER than "pass through". They are eliminating the pre-amp ALTOGETHER, and using Volume control provided by the OPPO itself. Even in "pass through" the analog audio still has to go through the analog audio circuits of the Onkyo, and a direct-to-amp connection eliminates that. There's a "less is better" mentality here, and depending on the quality of the rest of your equipment, and precisely what's going on in the "pass through" circuit design in the Onkyo you might hear a difference.
Next, using Analog for audio output doesn't alter what's happening on the video output. Yes, you would still see disc menus and player menus on the HDMI 1 video output direct to your TV.
Next, give it a try -- I suspect you will discover that using Analog audio output eliminates much or all of the lip-sync issues you have noted.
