RE: Corning *Optical* USB 3 cable for noise reduction...

The problem is that Archimago's measurements come with a 16 bit noise floor. If you want to measure low levels of jitter appropriate to 24 bit audio then there needs to be a much lower noise floor. With 24 bit resolution the noise floor on the FFT should be below -150 dB. (The exact amount of "FFT gain" depends on the FFT size and window.) Another way of explain things is that if there is noise in your system it will make it difficult to measure subtle distortion. It will also make it difficult to hear subtle distortion. This does not mean that the subtle distortion is not present and in a different context the subtle distortion might well be noticeable.

AS to audible hum or noise in a digital playback chain. If you can hear any of this then there is something wrong with the system installation or with the system components. Basically, if there's any noise you can't get rid of, something is junk.
