Here as though there are 2 topics:non-technical and technical.
About the first:
I expressed doubt that the signal quality on a CD at high frequencies will be good and made an argument (see above). And the impact on man and what affects him is the question.
Well, for example:
The case of life. In the presence of a person at the stake made red-hot red-hot regular tablespoon and suddenly attached to his arm. People got burned, but the joke involved the substitution of the invisible spoon in the cold. And that was done. People got burned from the cold spoons. Faith changes reality.
(Andrey Nefedov "Office reality")
If we are talking about the sounds with a frequency of 3-10 Hz (that is written in the annotation to listen to through headphones), the quality of the recording when copying is excellent.
But of course I suggest to still use the original wheels.
Briefly touch on the technical side for the last time.
About the normal drives, discs,codes, errors, and the speed of recording - see the link that someone gave in the beginning of the topic (better not write).
By the way:
My main thought is that the "uniqueness" of the audio stream with the usual CDDA - delirium. All repeatable. And no special bells and whistles it doesn't need. If player everything plays as it should (and is in General a NECESSARY condition for the spread of audioproducts), then this digital stream can security and save.
There is also all painted, just need lazy and like links.
Yes, there is sypka test the players and compare the signal quality when using
external DAC.
It is a pity that there are no tests, CD players for computers ( with their noise on the power - 5 Volts and 20-40 Amps!).
8 years ago, faced with the problem of reading poor discs.
Went to a friend on a computer firm for advice.
Here is his advice:
1. Plextor
2. Teac
3.NEK
On Plextor hand was raised - too expensive, and Teac 2 times cheaper, so I bought and have not regretted.
For the cost of it about
SD-player,more 2 sput
5-6 of these crafts (I don't remember how much they cost then, but I paid not frail). By the way, there (at the earliest) references explained the difference between drives from different manufacturers (whether they fail or not, as they varied in their fix, as the firmware chip in the player depends on the number and quality of bugs).
On the impossibility of loss of quality when the number and
the studios so the sound is recorded for SACD and DVD-Audio. T,E. for audio-maniacs, storage, and "future-proofing"
The Source Is>16 Bits.
Copy the 16 bits at least 1 000 000 times - they will be the same,
BUT:
Source ->16 Bit-> 16 bit ЦАП1->Output1
Source ->16 Bit-> 16 bit ЦАП2->OUTPUT2
Where Output1 +/-0,0015 % is not equal to OUTPUT2 +/-0,0015 %
(in the ideal case).
Source ->24 Bits (or even 20 bit)-> this is the standard and it is possible to tell with confidence Output1 or OUTPUT2 worse.And in case of interference and errors, guaranteed (with a huge margin) to do 16 bits.
In this technical part is done and
I will not write more
All I wish to purchase the original disks and a happy New Year!<
But that would not have to ask the author rip?
