There must be an HDCD indication in your receiver. Otherwise there is no way to know.
Thanks. I played around last night and I noticed no difference between feeding HDCD signal into my Onkyo 805 with 44.1kHz and feedign the 48kHz "garbled" signal.
My receiver did not (is not able to??) indicate a HDCD signal.
Therefore, I am sticking to 48kHz output.

Bear in mind that the original sampling frequency of SACD is 2822 kHz (64x that of CD), so 176.4 kHz is extremely *down*sampled -- not upsampled.
176.4kHz at 16-bit = 2822400 bits per second. Exactly the same as high-res DSD. It is neither upsampled nor downsampled, simply converted.
Just to add that the PS3 does all calculation for sound processign in the highest sampled frequency.

Yeah, they're not putting out 176.4 at 1-bit.
=D
The SACD playback is very good from the PS3. It's not going to compare to a $7,000 Marantz reference player, but it's definitely as good as the majority of North American standalone PCM Universal players I've listened to, including the Pioneer Elite DV-45 and DV-46.

Mate, I myself rate the PS3, but you really think it's that good?
If so, I can forget dreaming about gettign a "dedicated" SACD player.
Like I said, I rate it highly, but I couldn't be sure HOW good because all I had to compare it to was a Philips DVD-SACD combo(which was good for £60 in 2004!!!!!!!)
I've always said:
The Sony PS3 takes the original DSD data from a disk more-or-less intact. It can then do whatever it wants with that data. Which means, with the power of the cell - and well over a year's worth of a Japanese sound engineer-or-two's programming - who in turn had dedicated access to the Sony SACD team - then, even if that DSD data is converted to PCM, it can be done so in a way that surely SHOULD be a match for a high-end SACD player. Well, at least a mid-range one.
Is my logic flawed, or is it simply hard to swallow given that people would not want to accept the premise of what is essentially a bespoke £300 media centre outperforming a machine costing twice the price that can only do one thing?????

Agreed.
It's definitely not upsampled.

I think the answer is obvious as to why no DSD, they no longer make a receiver that handles it, it isn't part of Blu-Ray, no one makes DSP equipment for it. PCM won out, inferior or not.
Pioneer also no longer makes a receiver that handles DSD (the 84 was the last) and I would guess others will follow. SACD is being relegated to the 2 channel "audiophile" group and the home theater user who is not serious about sound quality (thus the conversion to PCM).
This is what really irks me about some audiophiles and how they are catered to. For some reason, Surround Sound is seen as inferior to Stereo. Both speaker configurations should be given equal attention and respect.
Yes, I know some feel that two channel sound is supposedly superior, but in my mind, the sound quality is improved with the extra channels in Surround Sound if one uses a disc like Stay In Tune with Pentatone and a sound pressure level meter properly.

THis must have happened mostly before my time so I hope someone else can shed a light on this: How long has it taken stereo to get taken seriously and eventually replace mono?

Pioneer may no longer make a receiver that handles DSD, but Denon, Marantz, Onkyo and Yamaha still do.
THe Pioneer 91-94 receivers have the DAC's to do DSD, but for some reason do not have a direct mode.

I've yet to compare it to hearing DSD direct, but I believe in North America most players with the exception of the Oppo 980H still do the DST>DSD>PCM conversion in the player...so it's probably a fair statement to say that it compares favourably to most standalone universal players that are in the same price range.
I paid US$400 for a Pioneer Elite DV45a in 2005 and I'm hard pressed to favour either one...but I cannot say how it compares to the high end dedicated players like the Marantz reference series.
I am going to try the 980H with an Onkyo 905 later this year and see how I feel then regarding PCM vs. DSD direct. For $169 the Oppo can hardly be considered taking a chance and I would like to have a DVD-Audio player with an HDMI connection, which the PS3 can't do.
In the meantime, I fully believe the PS3 team did an incredible job using the Cell for DSD>PCM conversion.

Hi,
does anybody know if the PS3 audio upsampling features (to 88.2, 176 Khz and bitmapping) also work when streaming audio files from the likes of Tversity or when audio files are played from the internal hard disk?
I am under the impression that these great features only work when a actual cd is in the Ps3 tray in fact my receiver properly displays pcm 88.2 Khz and I am NOT able to engage any post processing like DTS NEO or Dolby Prologic Music.
On the contrary, when I play lossless (converted to pcm from Tversity) files from Tversity and ripped CDs (AAC) from the internal HD my receiver does not display anything at all and I am able to apply post processing algorithms which could indicate that I am listening to 44.1 khz files.
Am I right in the above assumptions?
If the answer is yes, does anyone know how to make the Ps3 apply all the upsampling features for streamed files as well?
Thank you.
