I wholly agree here. you need to hear the difference. I have done listening tests with another audio friend who has a burner. We have two different burners and completely different audio setups, We agreed that there is noticable difference between source and original. There seems to be a high end rolloff. Imaging was certainly worse in both copies. I think that high end rolloff may give some the illusion that it now becomes darker and more wholesome sounding (especially on a crappy cd), but in my mind it trashes a good recording. The image is all wrong. even a lower output of some intrumentations. I encourage those to listen agian. Get in your sweet spot and get the spouse to confuse you.I find it more than conciendental that two people see things the same way listening to this info on more than one system, with more than one burner agree on this.
