I would like to know why I would need a switch as discussed here, where I would use it, and what it would do for me. My knowledge of switches is basically non-existent, hence the dumb question. If this is not the thread for this then just say so.
Currently, my system is played through a digital-only source using either streamed Tidal or my ripped library, both played through a Roon interface. My system now sounds better than through any of the high end CD players I have owned so I don't really have a problem but I am curious whether I am missing out somehow by not having certain peripherals.
The source set-up includes running Ethernet cable from my Orbi router (high speed Comcast) directly to an Antipodes DX Gen3 server, then Ethernet cable again from the DX to a Metrum Ambre (Roon endpoint), then I2S from the Ambre into a Metrum Adagio DAC.
I would like to know what I am missing, or how my sound could be improved by having a switch somewhere in that chain? I simply do not understand the purpose of the switch. Thanks for any helpful information.
One off-topic thing I find interesting here is the possibility of optical cabling as an interface. The Ambre (Roon endpoint) will accept an optical input and connects to my DAC using I2S so I am curious if inserting an optical interface would offer any improvements.
