i am sorry but as an IT professional i am staying with the objective view that bits are bits, if any of that stuff had any impact we would constantly have issues as normal datastreams are a lot bigger than the ones we need for streaming.
I am NOT saying that any of “that stuff” has any impact on reliable data transmission. Even the cheapest consumer switch will deliver packets 24/7 and not need more expensive components, such as a clock with low phase noise or an electrically quiet power supply, to do the work for which it was designed.
We are learning, however, that it wasn’t designed for high resolution audio. Please read what IT professional Dean Waters had to say, and then give us your thoughts on the role of networks in quality music reproduction. Thanks.
