As I understand it, the PS3 cannot bitstream the HD formats via HDMI and never will! It can bitstream DD/DTS via HDMI so why can't it bitstream TrueHD and DTS MA without some firmware update? What is the technical reason behind this?

or by a little pixie who lives in the cable.
Apparently it's because the chip that handles HDMI in the PS3 isn't capable of transmitting it:
Particular HDMI 1.3 chip in PS3 cannot pass TrueHD/DTS-HDMA bitstream
It doesn't matter anyway, just let the PS3 decode it and send PCM to your amp. Decoding is decoding - you get the same result whether it's done by the amp, by the PS3 or by a little pixie who lives in the cable.
If bitstreaming does not matter. How do you explain why my old Tosh XE1 and current Pio BDP-51FD's sound alot better (much more bass /louder) when bitstreamed to my amp compared to the PS3's LPCM?
As far as I am concerned there is an audible difference between the decoding done in a high quality AV amp than what is done by the PS3.

There is a difference. It's to do with the digital to analogue conversion process. The DACs in the high end amps are better than the decoding that the PS3 can provide.
This argument that lossless is lossless no matter where the decoding is done is clearly incorrect. By the same logic, all CD players would sound the same as they all decode lossless red book audio. Clearly not true.

Well Dolby TrueHD and DTS-HD Master Audio are both lossless CODECS which means that when you decode their signal you get out exactly what was put in. Whether the PS3 decodes it or the amp decodes it they will both end up with exactly the same data. 'Quality' doesn't come into it - a device either decodes it correctly or doesn't decode it at all. It's a bit like opening ZIP files - you can open them with WinZip, 7-Zip or Windows' built-in Compressed Folders explorer but you always get the same results.
So why does it sound different? I would guess at one of four answers (please bear in mind these are guesses):
1) It doesn't sound different, you just think it does. Human senses can be pretty subjective. If you put the same jam in two different jars, one with a label saying 'finest luxury jam' and the other saying 'no frills basic jam', then do a public taste test, I bet most people will say the 'luxury' one tastes best.
2) You may have set it up wrong - maybe you're not actually sending LPCM HD audio from your PS3.
3) Your amp is applying one sound processing mode to the PS3's signal and is applying a different one to the other signal, so you really are hearing different results.

Pick one!
My post said as far as i'm concerned. I didnt say that would be the same for everyone, Just my personal view.
Apologies if what I said was wrong in your eyes, but everyone has the right to their point of view without being ridiculed.
Hold yer horses there! The post 'nelviticus' made was both informative and humble. I saw no trace of ridicule.
That he took the time to explain how you may be mistaken in a friendly and helpful manner demands your respect, not your reproach or a defensive stance.
correctified ( ), and + 1
they were very helpful and informative posts, not condescending, malicious, or patronising in any way imho.

Rob, apologies for any offence caused. The "I" in no.4 was meant to refer to me - as in, "Nelviticus is just a random bloke on the internet" etc. etc.
I know a little bit about digital compression (I'm a computer programmer), a little bit about electronics (I studied it at college) and a little bit about home cinema and high-def sound formats (I'm an enthusiast and read about it in magazines and on AVForums). So, although I know a little bit about what I'm talking about I could still be wrong so don't take my word for it.
That's what I meant, sorry if it came across as rude.
