I have a Philips 765 CD dual-deck CD recorder (xmas present for wife). It doesn't sound very impressive as a CD player, but I have never been able to tell the difference between a digital copy made with the machine and the original disc (I use the philips as a transport through an MSB Link DAC). I have heard other people say they can tell the difference depending on the brand of blank disc they use. It probably depends on the transparency of your system and your ears. I would listen for yourself.
