It is just possible that cryo treatment could modify valve microphonics. It won't alter distortion etc.

OK - I hear you say "This is digital - it is 0's and 1's". Well it might be at one point, but I'd invite you to look at an eye diagram for the analogue output from the photodiodes in a CD mechanism. A CD mechanism is analogue through and through. Focus, tracking and data.

Error correction means that the data entering the DAC is perfect almost all of the time.
