With regards to HDMI information, the only known difference between components will be the jitter value.

the thought never crossed my mindstrapped for cash said:Simply because those parts sit between the disc and television in the image processing chain, not to mention the fact that the TV uses its own picture processing technology. It can never be the case that "what you see on the TV is what's on the disc." Even you would accept that the Pana V20 you owned introduced image processing anomalies (as does any other TV).
All audio visual technologies are comprised of chains that transport stored information (whether analogue or digital). No two chains are completely identical, even if they are made up of exactly the same products. There are simply too may variables at work, including the environment of reproduction, for this to be possible.
I've read widely on the myth of perfect fidelity from both a cultural and technological standpoint, so hopefully these claims are better informed than simple conjecture.
Anyway, I'm not having a go, Max, which I hope you appreciate...
yes there are believers and non believers and that's fine.aliEnRIK said:Generally speaking in hifi there are 2 main camps. Believers and sceptics. Now im not saying your either one or the other, simply that generally speaking most people gravitate towards one or the other
For example
I see genuine differences with BLU RAY playback between my oppo 95, S370 and PS3 on my not very high end Sony 46W5500
Ive seen reports like posted above where people (A group of people) couldnt tell differences on much bigger screens
Why is this? I could say everyone in the test/s have bad eyesight - but as that seems to upset many (Because we all know everyone has perfect vision). So lets talk about believers and sceptics
A believer (like me) will have -
A mains conditioner (I actually have 2 mains conditioners and a balanced mains transformer). A decent rack (Atacama and rubber feet inbetween the rack and the equipment). A decent HDMI cable (Van Den Hul). Decent mains cables (Like Russ Andrews, mine are copies). Fully calibrated equipment (Both camps should have this regardless)
A sceptic will have -
Dirty mains. Cheapest cables you can buy (or came free with the equipment). Equipment on anything (On each other in a lot of cases).
Lets just assume for a moment that the believers are correct. That to see genuine differences and have the eyes capable of seeing genuine differences that you NEED a clean mains supply, a well made HDMI cable and something half decent to sit the equipment on.
Perhaps, just perhaps, THAT is why people cant tell a difference (Including the online tests, and especially online tests done by sceptics)
Someone also mentioned that 1080P 24Hz pics should be the same off of any bluray player. But ive read that the sony S5000 goes through picture filters regardless of settings. Im no believer in filters, the signal should be as clean as possible to my mind, as any change might make some pics look better, but it will 'always' be at detriment to some others (And not as the director intended either way).
My Oppo 95, PS3 and S370 dont use any filters that im aware of, and I can see genuine differences watching blurays. Nothing major - not that old chestnut 'night and day', but subtle differences ive noticed over time.

Maybe, but a HDMI cable isn't the only link in the chain between source and reproduction.
Did this same debate occur with regard to DVD players? Cables aside, I don't see what's so different about Blu-ray. Both devices are designed to deliver digital information. Perhaps the greater resolution of Blu-ray means differences in performance are less marked, but there will inevitably be differences between players.
BenLaw said:Rik - can you explain any more about the Sony having processing hard wired in? And are you saying that if there were 2 players with no processing they would give different images?
bigboss said:So there are 3 types here; those who can't see any difference (this includes all those blind testers I mentioned before), those who can see a difference, & those who think they can see a difference (until they're disproved by blind testing).

sheehanjuk said:Personally I hope WHF includes some of old reference high-end bluray players vs the new models in the upcoming issue eg Denon 2500T or Cambridge.
