You can greatly improve the playback sound quality of your CD collection by purchasing a CD Nova Physics Group Memory Player, at a cost of
US$15,000, or you can do it for virtually nothing by following the instructions in this article! There are two questions you are probably asking at this point.
A. I thought the sounds of CDs couldn't be improved, so what are you going to do, the impossible?
B. What is a Memory Player?
To answer question one, yes, the playback quality of your CD collection can be greatly improved.
How? We first need to give you some background on how a CD payer works. When the CD laser reads the digital information recorded on the music CD, it is reading microscopic pits on the CD while it is spinning at high speed. It makes mistakes! So rather than create silence, or a click or a pop sound, like vinyl LP records do, it makes an educated guess as to what the sound should be, and plays this back. Well that's great, but it can make the wrong guess. This then creates sound distortions.
The Nova Physics Group Memory Player is a device created to solve this problem. Here is an extensive article on the device,
1. It has a special high quality CD transport to read the music CD on a very stable platform.Thus less read errors are created in the first place.
2. The Memory Player has specialized softwarethat re-reads the CD disk error location up to 90 times until it eliminates the data readerrors.
3. It stores the error corrected CD data in memory, and then plays back the error corrected music it recorded from the CD disk though a high quality Digital to Analog Converter (DAC), and amplifier.
Clever isn't it! Well you can do all this, and get close to the memory player sound quality, by doing the things listed below, for very little cost.
You do need a computer with a CD/DVD player to do this. The better quality the CD/DVD player the better.
1. You download and Install this free software “Exact Audio Copy” (EAC) from here http://www.exactaudiocopy.de/ and install it on your computer. This does the error correction for you. By the way, this software can also be used for damaged CD datarecovery.
2. You set this software up to copy your music CD collection in WAV format, in secure mode, in high quality sound. Once you have the error corrected CD recorded on your computer, you don't need to do this again. It can take 20 minutes or more to error correct just one music CD.
3. You can now play back the super recorded CD version at will, off the computer hard drive. If you want even better sound, you copy the music files onto a plugged in high quality USB flash drive, and then play it back from there. Corsair Flash Voyager Flash Drives are well built and to a much better quality than your average USB flash drive. This eliminates drive jitter and other errors that may be created from playing back the music file from the spinning computer hard drive.
4. Play back the recorded CDs through a good sound card or Digital to Analog Converter (DAC), or network player, and then into your home stereo system, to get the absolute best playback sound quality.
Once you have heard the difference in sound quality between playing a CD normally, and playing back the error corrected version, there is no going back.
