Madisonears, Unless you have made copies yourself and compared the diffrences between diffrent brands and recording methods I don't see how you can presume that they don't exist. It would be like me saying that Krell amps are harsh and edgy sounding and having never owned one, because that's what I've heard. Carl I should send you the copy and the original, that I've made where the copy sounds a lot better, so that you can hear what I am, email me.
