Fibre optic cables are able to transmit data at huge bandwidths without (as far as I am aware) huge issues, Yet there appears to be an audiophile consensus that coax sounds better than toslink. Can anyone explain why this might be. Therre is a tremendous amount of interest on this forum for software and firmware mods which are intended to improve the sound from a dac connected to a Touch. It is difficult to see what effect these mods can have other than through the transmission of electrical noise which would presumably not be passed via toslink. So why is it that toslink is supposed to sound worse than coax. The only explanations i can find are 1) the signal sent by toslink leads to data errors in the receiver (ie the receiver cannot accurately read the bits) or contains a large amount of interface jitter which the dac is unable to remove. Is this something inherent in the toslink medium or is it the fault of bad transmitters? 2) the operation of the optical/electrical conversion in the dac asversely affects the dac or analogue stages somehow
