Do we really need anything greater than 24/96? Opinions?


It's really difficult to compare resolutions with different masterings, delivery methods, sources, etc. I have hundreds of HI-rez files (dsd, hi bit rate PCM, etc). I have to say that even 24/44 is probably revealing the best a recording has to offer. Obviously, recording formats, methods, etc all play a huge role. I'm not talking preferred sources like vinyl, sacd, etc. I'm talking about the recordings themselves. 

Plus, I really think the recording (studio-mastering) means more to sound quality than the actual output format/resolution. I've heard excellent recorded/mastered recordings sound killer on iTunes streaming and CD. 

Opinions?

When I say 50% of the information is missing what I mean by “information” is that dynamic range is doubled and resolution is increased considerably. I am not (rpt not) trying to say there is twice as much data available to the DAC as was on the CD 💿 Obviously, the data on the CD cannot be changed. But what can be changed is how the data is pulled off the CD. Yes, I know what you’re thinking - doesn’t Reed Solomon and the CD laser servo system take care of all the errors? 😳

We know, for example, the reason there IS a laser servo system in there in the first place is because the original designers were aware that the CD 💿 flops around while spinning, that the nanoscale laser beam cannot stay on the nanoscale data spiral without help. It helps but is not 100% effective. IT CANT KEEP UP. The laser beam is an out of control locomotive roaring down the track! 🚂 

So when you add up the increase in dynamic range, the increased bass performance, increased air and increased signal to noise ratio SNR you get 50%, if your system can handle it. And I’m being conservative here. Who wouldn’t want to DOUBLE Dynamic Range? It’s subjective. Put those books down! Use your ears. And yes, I know what a lot of people will say, “but my system already sounds fabulous!”

There is no substitute for signal to noise ratio.
www.2l.no  has plenty of free hires and redbook samples of all kinds. It also shows the source format, almost all studio DXD. It is easy to compare the same piece of music at all sampling/bit rates. Ask somebody to assign new ABX file names (do not check file sizes) and play them as long as you like- blindly. Note your ABX test choices. This double blind self-test will tell you the truth. About the hires and/or about yourself.
VI,


Your 50% information theory, which was previously 25% is a fantasy not a reality. Unless your CD is severely damaged, the multitude of control system and data correction methods on a CD player take care of all the things you claim and eliminate effectively all the errors with few exceptions.  Modern CD players also buffer and reclock so you can't even claim timing issues. 


VI, if you had any, and I do mean any data to back up what you claim, that data very easy to produce, then you would be broadcasting that from the rooftops. You do not. You just have an unfounded hypothesis. Basically a fantasy about the missing "information".
Tatyana69,


44.1/16 upsampled to 192/24 is still 44.1/16. A standalone upsampler is just a more accurate digital resampler or it is intentionally making the 192 signal less accurate which is okay if you like the result. 


Your post would suggest 24/96 is enough?
@atdavid You are completely right. I have worked with developing optical media testers for the industry for 10 years. When it was thing.
And I got scared when as a newbie to this forum reading about this misinformation about the optical media.
Just think on the simple fact that we developed and had for many years ago, servo systems that not only read but also write at 1x, 2x, 4x, 8x, 16x, 32x, 52x and higher speeds!!
Why should we suddenly today have issues with servos to track at 1x for listening on music if you do not have a lot of scratches in the disc.
