I saw this testimonial on the totaldac for their switch:
"Many enthusiasts think that the sound of a digital player is not as good as a CD player. That's because your digital player system can only exert less than 60% of its performance without adding a network switch. There are two concepts for adding network switches. Of course, the prices of network switches are also very different, and the quality is uneven. There is no doubt that adding a network switch to a hifi network playback system, especially the advanced network switch can directly double the "value" of digital player products or even show the value of several times the machine itself"
I agree with this after adding my switch. It does get you a lot more performance from the dac/streamer.
