Was wondering if anyone here that hears a big difference between both. I don't actually hear a big difference, I still enjoy the sounds from DVD.... sometimes surprisingly better experience than watching blurays.

Recent dvd movie I watched was TROPIC THUNDER, the explosions and bullets were awesome, made me jumped (similar to SAVING PRIVATE RYAN last time).

I feel lossless sounds from bluray have slightly higher clarity and bigger space feel (like those amplifier sound fields/processing). But in terms of punch, seems less.

What you think?

totally disagree....
may I ask what sound system u use?

Yup, strongly disagree. Big difference between lossless and lossy.

Like Mpyw said, need to know your system bro.

maybe ur sound system unable to show out the potential of blue ray.curious about ur sound system oso.

Why depends on sound system? You mean lossless require special equipment or new speakers?

I'm using Yamaha 663 amp and PS3, output to Klipsh 6.1 speakers.

How do you classify as 'big difference'?

lolz...interested in tryin out these ppl sound system?
you will hear the differences then

And in case you are wondering about my PS3 or 663 settings, it's not a problem, all checked and researched on forums eg. DRC off, PCM output.

Lossless is from PS3 (PCM/HDMI).

Lossy from OPPO970 or Panasonic RP82 (Bitstream/coaxial).

Sure, don't mind listening since there are no HT demos for lossless vs lossy in showrooms.

How do you hear the differences? You actually compare same movie (DVD vs Bluray)?

I've personally compared Matrix3 and Kungfu Hustle for DVD vs Bluray..... very very hard to hear difference.

Some Blu Ray do come is lossy format for their sound, some in all lossless, some mix so is DVD.

If both the DVD and Blu Ray version of the same version have lossless audio files, then they should sound the same.

The reason we ask about the system because some people uses optical from PS3 to connect to their receiver, which will mean all audio will be lossy and the 5.1 PCM track will be downmixed to stereo. Or set to bitstream when using HDMI which will downconverted to lossless core DTS/Dolby Digital only.

Laowai, looks like your system is in a good setup. I'm surprised that you couldn't tell the difference.

To me the difference is so huge, I'm not buying any BD without a lossless track. More details, accurate imaging, directional, wider soundstage, deeper and more charasteristic LFE. Example, when a glass shatters on the floor, you will hear the pieces bounce 5 times on lossless track, but on lossy, you'll probably only hear 4 times, due to compression. That is why the track is called lossless. Exact duplicate of the studio master.

I did a blind test on my own using Casino Royale between the DVD and BD, the music on the opening Columbia Pictures montage itself already giving me goosebumps. I'll say again, the difference is huge.

do you think its preferences...?
well some ppl like fat girls some like thin...works the same on audio

Nothing to do about preferences. It's about the difference between lossless and lossy.

The word lossless alone will make you understand what it is. I know that in the end, our own ears will be the judge, but the technical part itself already explains a lot. Lossy audio the normal the bitrate is 448kbps, but lossless can be around 10mbps (example from Celine Dion BD) and more.

If want to compare, don't compare between different movie, must be the same movie like I did with Casino Royale. And must be the exact (proper) setup.

It's not about cables brands or speakers here, or any kind of placebos. But the audio track, the source itself.

Aiman, your lossy and lossless were from which player ... same PS3 or different players?

So far, I've been testing simultaneously via 663, switching sources to and fro (DVD <--> DTV)

Will try to do more comparisons DVD vs Bluray.

But so far, I can say from my experience, I've not been impressed with lossless. Without doing comparison, just listening to bluray alone, the feeling is just not the same. I guess lossy is already very good to begin with eg. listening to Marriott's AV show's power HT setups last time was testimony enough.

I guess I expected too much from lossless, based on the difference of technical specs.

Both DVD and BD tested using PS3.

I guess, like I said before, in the end it will be our ears to judge. But I won't upgrade to BD if I can't hear the difference, 50% of movie experience is sound. I would never pay more for BD, and certainly won't upgrade to HDMI receiver if it won't bring any new experience to movie watching. An old receiver with coaxial and a DVD player will be sufficient.

In fact, on BD, the sound is more obvious upgrade than the video, at least to me.

Well, to each their own.

Wow, now I believe "to each his own".

To me, the BD biggest jump in improvement is towards video.

Audio improvement very negligible.



So you tested by inserting and removing the discs. And also switching the HDMI (PCM <---> bitstream), or you played DVD as pcm only?

You started this thread ask for opinions right? So I gave mine. Nobody's forcing anyone to change their opinions here. Enjoy your BDs bro!

lol?
why so serious?
these stuff are very subjective dude...

to me,

the lossless sound have:-
1. more clarity
2. more dynamic
3. better LFE
4. better surround effect

my setting:-

PS3 --> PCM --> Yamaha RX-V861 --> PSB Alpha 3.0 speakers, Velo Sub & Sony surrounds

I can definitely hear the diff, even my wife can.....

I'm using PS3 to play blu ray movie, does this means I cannot get lossy audio as it is connected to receiver via optical cable.

u will get lossy sound i.e. normal dolby digital or dts, if you connect through optical from the PS3 to the reciever and set the PS3 to "bitstream" the signal.
