48k is the typical material, but it supports a lot of stuff including 96k, but only in stereo (I have DVDas with additional 24/96 tracks for regular DVD players).

DVD and DAT used 48 kHz as their base rate, while CDs used 44.1. This setting on the PS3 is for CD playback only. I think Sony made it a choice, and defaulted to 48 kHz because for digital transfer to a receiver, they all support 48 kHz, and while most support 44.1, the upsampled rates of 88.2 and 176.4 are less supported. Handing a receiver an unsupported sample rate can do anything from produce silence to a speaker/ear destroying screech (if the volume is turned up). So 48 kHz is safe.

The HDMI interface is able to tell the PS3 which audio rates/formats are supported by the connected device. But when using the optical connection the user must check the right boxes. One thing, DTS-CDs don't work when upsampled. Going to the output settings and unchecking 88.2 and 176.4 while using the setting I mentioned before, will make DTS-CDs work correctly, and not really have any hindrance on any other discs. Well, it will affect SACDs, but since most PS3s out there don't even support SACD playback it's safe. Though if you do play SACDs, you need to choose between them and DTS-CDs (or change the setting each time).

ClubNeon, I see that you have an Elite 79avi. I have the same DVD player and I find it is really good at playing CD's with the Burr Brown DAC's.

I was wondering though what you see when playing a CD with the 79 to your 1018 (I have the Elite VSX-01 which is pretty much the same receiver). When I play CD's (through the 2 ch analog connection on the 79), the receiver display shows "96 kHz Stereo" which I think is odd because a CD, as mentioned, has a sampling rate of 44.1 kHz. 96 is clearly not the multiple I would expect for upsampling. I'm a little worried about the fact that it isn't a 1x or 2x upsample. The "Pure Audio" feature on the 79 doesn't seem to have an effect on the receiver display.

Any similar experience/insight? Thanks.

You're using the analog outs and it's showing a sampling rate? There's no sampling involved with analog it's a continuous wave form.

I don't have the stereo outs on the 79 hooked up, but the 5.1 connectors instead; they're connected to the 7.1 input on the 1018. When I use the Multi-Channel input, it doesn't show me a sampling rate at all.

If you're using a pair of stereo ins on your receiver, you're taking the digital audio on the CD, turning it to analog by the 79, then the 01 is turning back to digital (probably at 96 kHz as the display indicates), applying processing, and then converting back one more time to analog. If you use the multi-channel ins, you'll bypass the extra conversions, and processing.

Really though, I prefer the HDMI connection, then applying Dolby Prologic IIx to the stereo signal and creating a 7.1 upmix, and then making use of the MCAAC processing to attenuate standing wave peaks. That's over the pure, direct method. When I had my ancient Sony receiver the DACs in the 79 were definitely superior, and it only had old-school, 4-channel (left, right, center, surround) Prologic. Now I can't tell the difference between the 79 and the 1018.

I have both the 2 ch and 5.1 ch analog connected (probably redundant in most ways). I know that when you select Multi Ch, the receiver doesn't apply any processing. Similarly I found that when using the CD input (2 ch from the 79), in standard and Direct modes, the 96 kHz rate was displayed. In Pure Direct it does not. I guess the only way the 01 won't convert back to digital is in Multi Ch or Pure Direct Modes.

Thanks for the help.

That's funny you reply to this now. I just hooked my PSP up to my 1018 via stereo analog cables last night, saw the 96 kHz display, and thought of this post.

Glad I could help.
