If you use eac you can prove that the rip you have made is perfect. On my six year old bog standard laptop, I have copied hundreds of CDs and only one needed to be reread (it was dirty) to get a perfect copy. You do not need anything special. There are peculiar individuals who instead of being happy that modern technology can work perfectly even if it is cheap insist of spending huge amounts on unnecessary nonsense like magic mains cables or special CD rippers. They simply don't understand technology. Ignore them and you can spend money on things that do matter like speakers or red wine.
