The statement about the Nova player that is quoted in the OP is misleading. What occurs "hundreds or even thousands of times per disk," which in conventional players and transports is subjected to what it refers to as "Error Code Correction," results, at least in reasonably contemporary implementations, in bit-perfect recreation of the original data on the CD. What it refers to as "Error Concealment Correction," which results in less than bit-perfect recreation of the original data, only comes into play rarely (not at all on many CD's), in extreme situations such as severe scratches, or disks that are otherwise in poor condition.
See my post here, and the Wikipedia links provided in my previous post in that thread. Also see two posts in that thread in which Steve provides added confirmation, one of them stating that "with a clean CD, there are virtually no read errors with modern read heads. There will be some differences in jitter with each play however, based on lots of things, such as AC power, ground loops in the system etc."
The quoted statement about the Nova player appears to indicate that it disables BOTH error correction and error concealment until such time as its RUR process has been unsuccessful. If true, that would say essentially that their approach creates a problem which it then solves.
