Just for reference! It may not be absolutely true which depends on whether you believe or not.
Question #1: Is the digital data in original CD same as the copying data in your hard disk?
Answer #1: Yes!
See statements as below. (Ref: http://www.lessloss.com/about.html)
Digital audio data is 'just' 0's and 1's. There may be many formats (.wav, .aif, CD-audio) but the information is still digital. There is no loss during format conversion, provided the formats don't utilize compression.
Copying CD's (if they aren't damaged physically) is a lossless procedure. You can extract CD-audio with your computer and generate a file on your hard disk. Compare this file with the file created when you extract the same audio using a $30,000 player, the resulting two files are identical. This is proven by countless mathematical experiments and by HEX comparison programs.
Question #2: Will hard disk perform better than CD transport in transmitting digital data to DAC?
Answer #2: Yes!
These comments were done by people in Hong Kong. But, better to express in term of “jitter rate”.

Question #3: Laser reading mechanisms in all CD transports are digitally perfect, even if they cost as low as $30. Will $30,000 expensive CD transport perform same jitter rate with $30 cheap CD-Rom?
Answer #3: No!
See statements as below. (Ref: http://www.lessloss.com/about.html)
Digitally, a $30 mass-produced CD-Rom at 52x does exactly the same job in a few minutes as a $30,000 CD transport does in real-time. If you don't believe this, then all you need to do is digitally record your favorite tune from a $100 CD player into your computer (provided you have a soundcard and software that doesn't add yet more lies into the equation, which is often the case, so beware!) Then borrow the most expensive CD transport you can get your hands on and repeat the experiment. The resulting sound files aren't just similar, they are identical! This is not a theory. This is proven by much experimentation and mathematics.
But the $30,000 CD player does indeed sound better! How do you get a $30 player to sound the same? The first and most important step is to slave the CD transport to a DAC which is the Digital Master. That's it. This simple step alone is worth half the price of a $30,000 CD transport. (i.e. clock sychronization problem)
Conclusion:
Even if it is true that a HK$500 hard disk performs better than a HK$10,000 CD transport in digital data transmission, this concept is quite difficult accepted by most of HiFi fevers or DIYers in psychological point of view.
