Alas I am not a subscriber, so all I have seen are the comments about the article. My intention was to point out that a single study may not prove a point, and several people more well informed than I were skeptical about the results.

Did latest firmware uppdate do that?

Can anyone play CDs or SACDs with latest firware update?

Which PS3 do you have? 20gb? 40gb? 60gb? 80gb?

I too would like to know this as I specifically purchased my PS3 for its SACD capability. I do NOT want some firmware to wipe that feature out.

There is no chance that Sony will disable SACD playback with a firmware upgrade. They have never even removed any documented feature that was added by an earlier firmware upgrade. The only known example of a remove feature is an officially undocumented one: DSD-to-DTS transcoding in v2.00 (out in v2.01); see the PS3 SACD FAQ.

I dont know the technical term but what are the technical "numbers" or bitrates between SACD, DVD-A compared to the three Blu Ray lossless formats? How close is SACD to, say, PCM on Blu Ray?

resurrecting this thread to ask for clarification on something -

the only way i have found to matrix 2-channel stereo SACD'S to multichannel with my receiver (Onkyo 805) was to de-select 88khz from the ps3's audio output screen. That also let me matrix regular stereo music streamed from my computer....even after de-selecting it, I can hear SACD at 88khz according to my receiver (SACD multichannel still plays at 176khz, too).

I really like the sound of all-channel stereo from the 805 with 2.0 sacd's, but am missing out on a lot letting the 2.0 sacd's downsample to 88khz?

is there a better way to go about this?

i'm assuming you meant "de-select 176[.4]kHz" in order to get 88.2kHz stereo output from your PS3 which you let the Onkyo 805 process (i.e. matrix) to all-channel stereo. I found the same thing with my Onkyo 605, in that I have to down-res to 88.1kHz in order to get DPLIIx "music" processing of stereo SACD recordings. I'm pretty sure it has to do with the receivers' ability to only layer processing on sampling rates of < 96kHz. Anything above that, e.g. 176.4kHz or 192kHz, is passed straight thru.

I don't know this for sure, but my guess is that the PS3 does the same processing of DSD to 176.4kHz LPCM as it does for 88.2kHz, it just omits every other sample from the stream (in effect halving the sample rate.) You lose half the bandwidth in effect, but that's still twice the sampling rate of redbook CDs. You lose some aural time slices (which I'm not sure one can really notice in listening), but gain processing on the receiver-side. At least, that's how I understand things to be.

Of course, I don't understand why they chose 44.1 / 88.2 / 176.4 kHz sampling rates for the DSD to LPCM conversion either...why not 48 / 96 / 192 kHz? Oh well.

In the end it's whatever sounds best to you that counts.

It is more natural to convert DSD (by spec DSD64 is 64*44.1 for easy down-conversion to Red-book) to some multiplier of 64 than to deal with fractions to get to multiplier of 48.
