Streaming over fiber vs. cable Internet


Has anyone found that Internet delivery via fiber instead of by cable improves the sound of streaming via Qobuz or Tidal? For the longest time, cable Internet was our only alternative to the old DSL days, but now it looks like we may have a fiber option.

Old question, but he may be talking about Xfinity (cable internet) vs. AT&T (Fiber internet)
Sorry if it was an old question, but yes, that was my question.  We are cable customers in the big city and increasingly our service is interrupted as usage in our community surges.. My nephew works for a fiber-Internet company in a college town and he tells me there is no comparison in terms of available speed and reliability.  I was wondering if sound quality would improve too.  It would seem to be likely a yes.
