I stumbled upon this when I was researching the topic.
 
Quote:
  For those who wihs to output 24/192 from PS3, you need a HDMI switcher unit like the Porta or Monoprice equivalent.
See http://www.audiocircle.com/index.php?topic=82217.0
 
By connecting HDMI out from PS3 to the Porta and using the coax or toslink out from the Porta to my Esoteric SA-50 DAC, I am able to get 24/192.
 
FYI, my PS3 does not have sacd and I use my Esoteric for that instead.
 
Hope that helps

 
Can anyone verify this or is it simply just up scaled?
 
I want to take a Little Dot 1+/Bifrost Uber to my friends house, he has a working PS3.
 
Where can I buy the product that this fellow is describing?
 
Also how do I set up the audio settings?

Why not just set the PS3 to 2-channel stereo, connect the PS3 to the Bifrost using optical and be happy with the sound you get.

I want the best sound possible, I do not want to bottle neck the system.

So far, as I can tell, when the PS3 is outputing 2-channel digital PCM audio, HDMI and optical are going to offer the same audio quality.
 
If your starting out with HDMI full 8-channel 24-bit/192Khz uncompressed audio and want to send it to a external S/PDIF (optical or coaxial) input on a DAC (for a headphone), you need to use something that can do Headphone surround sound processing, like an Astro mix-amp or a receiver that can process headphone surround sound, most of those external switching boxes you are looking at only convert digital to analog, they are like a fancy DAC, but offer zero surround sound features.
If you send 8-channel (using HDMI) of audio thru them and you output with the 4 mini jacks, you get 8-channels
If you try to output using optical, it will only be 2-channel and you will lose the other 6-channels of sound.

So what you are saying is that optical will sound like normal/the same since it will be two channel audio?
 
I might get a mixamp for gaming, I just don't know if my headphones have a large or accurate enough soundstage.

Yea, the 2-channel PCM digital audio signal is carried about equally, by optical or HDMI.
 
Some people plug their 250-Ohm DT990s into the Astro mix-amp, so if you headphones are under 250-Ohm, should work with the mix-amp.

Where can I buy this porta thing that the guy I quoted talks about?

You just posted in another thread,

Today I feel the same as you as well, I just brought the Bifrost Uber and Little Dot 1+, and I hooked it up to my friends PS3, but the change in audio quality us underwhelming. I was expecting a mind blowing change in sound.My problems could be that I am still burning in the tubes, the tubes that I have bought are not up to par (GE JAN 5654W) and maybe my quality of music is not up to par, who knows.


Like your efforts to buy an uber expensive DAC/amp setup for <$200 headphones to improve the SQ, you are trying to throw money at the electronics of an audio setup to improve SQ. You should first verify whether or not the Sony optical output supports the sampling rate/bit rate you want for 2 channel audio. Consult this thread on the PS3 over at AVS.

Even if it doesn't, the path to better audio will generally be better headphones than the Shure SRH840, not spending $700 or $800 or more on electronics to eke out that extra 1% in audio quality.

Can anyone explain this to me, I have no idea what they are talking about. They are attempting to play FLAC files on the PS3.
 
I found out that it may not be possible to play 192 khz.
 
"Ooh, you're a tricky one. I like that. I'll mess around with it to see if I can get 48000 to play. But the 24-bit would require adding a line specifically for 24-bit and would most likely require coding to AAC or something similar since only 16-bit WAV is accepted...I think.
If you notice the line for LPCM, the mime type is l16. This means 16-bit LPCM. The mime type for 24-bit LPCM would be l24 which is not recognized by the PS3 as far as I've seen.
Now, as with the resampling to 44.1 or 48 kHz, are you certain that your original is one of those? If so, then it shouldn't resample at all and should actually just play it normally. However, if it is something along the lines of 96000 or so, then you will need the resampling button checked."

 
"It appears to work well in 1.90.2 which is a dev release. Take a look at it and download the dependency version before renaming to PMS.jar and placing it in the program directory.

Correction: I fixed it! As it turns out, for LPCM data, you need to have it separate from the wav section. Create a new line in the PS3.conf file under audio and make one out for Supported = f:lpcm a:lpcm n:6 s:48000 m:audio/l16
If you have/use DTS, you'll need to separate that one as well but find the correct mime type for it. But this should handle everything. ^_^
Oh, and don't forget to remove references to LPCM from the wav line."

Talk to the guys in the PS3 thread I linked to above. I would imagine they would help you. AVS is to home audio as head-fi is to headphones. If you look at their FAQ in the first few posts of that thread, you'll see their goal is to know EVERYTHING audio about the PS3 :)
