This is likely to occasionally cause scratches. When the disc is loaded, the surface of the disc is in contact with the loading mechanism.
If done right (reliable software for extractning, high quality CDRs etc.) you will not hear any difference. A decent alternative could be a HTPC with a good external D/A converter (for best possible sound). That way you could play back anything you want directly from the hard drive.
No, it sounds reasonable enough.
I apologize for the totally humour-free answer.
thanks!!!
