I'm wondering whether the brand and/or formulation of CD-R makes any audible difference when copying Redbook CD data from a computer hard drive. I'd be particularly interested in any studies showing differences in the recorded data, or blind tests showing an audible difference. In my minimal, sighted listening tests, I've never noticed a difference in sound between the original CD and the CD-R copy, except when there's an obvious, drastic problem with the burn.
Thanks.
