I don't remember if it was the latest TAS, but I recall Robert Hartley talking about potential CD read errors, and stating that they should be rare. I think the reasoning was much deeper than that we would hear clicks if there were read errors. There was a discussion of the error correction encoding and he detailed how many consecutive bits would have to be misread and/or unable to be read, to generate a genuine read error.
Reading off a CD for playback should be basically error free. Reading off a hard drive or out of RAM would be literally effor free. It just seems that the handling of digital files in the digital domain is a solved problem.
