All this is also equipment dependent and also the optical isolation does not really happen if you also hook up the coax at the same time , so test should be performed with coax disconnected. The bottlerneck off toslink is usually the reciecwing and sending parts , cheap not precision stuff . (192k can be hit and miss ) . It usually has worse technical performance than coax with the exception of galvanic isolation . But in reality on almost any equipment both these interfaces have for example jitter way below human detection level . So the expected outcome in a proper test is to not hear any difference its not a mystery :) If one hears an actuall diffrence it's more of an indication of problem somewhere !
