DVD-A Playback Unit S/N Question

Know Nothing · 7th May 2008, 09:46 AM

The question which can only be properly answered by wise soundmen like the ones around here is :

The playback of a DVD-Audio (LPCM Stereo 24 Bit 96000Hz )on a player which a 24/192 DAC whose s/n is 95 Db...Does it makes any sense ?- I mean the outcoming sound will be superior to the one that i'll get playing back the same program converted to CD ( 44100Hz 16 Bit ).

The point is that i'm updating my car head unit. I can go for a unit with a s/n 95 Db or for a unit with a 105 Db s/n but losing many other features.

Given the same amps and speakers. Will the DVD-A playback be a hell of difference because of the stated s/n ratios ?

Please answer me...I need to make an informed decision. Mi nickname suits me fine...

If you think that inside your car there will be a noise in the 50dB to 80dB, you shouldn't worry too much, do you??

Well, i know that sound on a car will always be far from pure.

I posted the question for the sake of knowing how the S/N ratio of a DVD playback device would hurt the 24 Bit resolution. Given that the playback system has 24/192 DAC ( I mean it does not truncate nor downsample ).

which brings us to the question.

Why do so many producers and engineers think that higher sample rates
are a waste of time??

There has been many threads here asking about sample rate and what people thought about 96khz and 192khz.

the overwhelming response has been that it makes no difference to the sound.

And some geek even posts a scientific paper with lots of pencil neck jibberish telling us that we are mad if we can hear any difference.

So why do equipment manufactures keep making these products.???

Yeah that was part the spirit of my question. I'm a regular music consumer so i've no tech knowledge but somehow after reading Bob Katz's bible i learned to appreciate many details of the music i listen to.

But may be because i'm a mere music consumer my insight could be useful for the mastering pro's. I still have not concluded wether the sample rates beyond 96000Hz are useful or not. What i'm convinced though is that bitdepth does really matter. In spite of having read papers telling that to the human ear 16Bits sound almost like 24 my ears keep on telling me that 24 bits sound more deep,wide and detailed than 16.

What i'm doing lately is remastering ( Sorry for the use of that word ;) my favourite cd's in the 96000Hz 24 Bit realm and staying there by burning onto DVD-V or DVD-A.And on my "high end" hifi ( 110 Db Dynamic Range 115 Db S/N ) it pays.

So what i wanted to know is if playing that DVDs through a worse ( 95 Db S/N DVD player would put these DVDs sound into a CD quality.Or it would still sound better than a CD but of course not as good as they do at home.

Are you somehow obtaining the original masters for your favorite CDs? If not, you should reap no benefit from ripping CD audio to 24/96. I have the feeling I'm misunderstanding you (?).

Of some local bands i do have the masters.

But recently i took off the shelve Bon Jovi's 1992 "Keep The Faith" CD, and through wavelab and Izotope RX i converted it to 24/96 ( Padding zero's ;) Then i did some uncompression ( Back in the day the loudness war was erupting ).Since the uncompressing was done at 64Bit internal and 32 bit float output i just "caught" the 32 bit float output and dithered to 24 Bit staying in 96000Hz. Burned to DVD-A and it sounded more natural than the compressed original CD.

The idea of this experiment came off Bob Katz's book where talks about remastering cd's input in high res and staying there by delivering in DVD-A format. S
