Where do people get this figure that digital has 1/20th of the information of analog (vinyl)? 
 
I was always under the impression that CDs and Vinyl have equivalent inherent sound quality (excluding physical distortion of a record).

You are more or less correct. Information is ambiguous term when reffering to analog, but in principle it is defined by the ratio between full-scale and the noise floor.
The same is true for digital. And in many cases the performance of 24 bit audio (or even 16 bit) is simply not achieved because the noise floor is too high.

In theory 16 bit audio has a theoratical dynamic range of 93dB with dither. If the ratio between full scale and the noise floor of a vinyl record is 96dB it has a the same amount of information as a 16 bit digital audio file. The 3dB difference is the result of dither, but that doesn't really matter all that much.\


I don't see how this is related to the rest of this thread, though.

I guess it comes from the impression that vinyl is analog, and better represents the infinite amount of steps between two values that happen in the real world than digital, which is for CD, 44.1 thousand samples per second saved into 16 bits of volume information. I've seen some people say that analog = infinite. That argument fails to realize that signal-to-noise ratio limits the dynamic range of LP, and that the grooves of an LP can't be crafted "infinitely" precise either limiting the frequency response. Now dynamic range alone is a poor argument to favor CD, because most CDs are digitally limited in dynamic range to appear louder (ie. Loudness war), and LP records are usually mastered to have more dynamic range than CDs (exceptions exist of course), even though CDs are technically superior (70dB LP noise floor vs 96dB on CD, more with dither). CDs also don't suffer from the clicks and pops and distortion usually found in a midrange LP system, that alone makes it superior to me.

But yeah, LPs are usually mastered better, and I'd argue that a good LP system with no audible noise floor can sound better than a more compressed CD master. If the masters are the same though, CD is better of course. It's not the fault of the format, as a format CD is superior, looking at SNR and dynamic range and the lack of distortion and pops and clicks vs. LP, most CD's are just digitally limited (not compressed, limiting = high ratio compression, basically flattening the dynamic range by a factor of 1:10-1:20)

lol I'm doing that right now



My IT teacher disapproves of Turtle Beach. I have feeling that his an audiophile too.

>> calling yourself audiophile, still using a soundcard.
 
plus, he is right, get yourself a DAC and bypass it :p (don't take this too serious, haters gonna hate .etc)

the sound card has a good dac on it ,but I here you. I rather use a nice sound card then a dac
there is some things that a sound card dose that a dac can't do tho, a top$ dac would be better

edit
I have this

he also said hi fi headphones and speakers are a waste and all you need are the earbuds like or  the ones that come with a ipod  or some logitech crap lol
he was saying that sound cards where a wast all together and everything should be onbord but gpu's

You know you're an audiophile when your friends ask you to research headphones for them, and after finding out what they want, you already know what they should get.

[size=small]You know you are an audiophile when you are watching a belly dancing performance and all you can think is "man this sound system is crap, where are my headphones?".[/size]

Or rather, you know you're an audiophile when you are watching a belly dancing peformance and all you think is, "Damn, these headphones sound amazing"
