Use of Switch to Improve Streaming Quality

Hi to all,

This question pertains to the advantages, if any, of using an ethernet switch between router (Eero device actually) and the streamer. The streaming service is Qobuz. I have gone over many threads on streaming and am now convinced a dedicated streaming device is the way to go to enjoy the best result in the audio experience (interface and sound quality). Therefore that will be next as the major addition to the sound system. The Devialet Expert Pro provides a terrific ‘all-in-one’ solution that is very competent and rewarding for listening to music and not without a few occasional glitches. It is most likely not on the level of a dedicated streamer, hence the decision to move forward on this type of solution when finances permit.

The particular question is regarding the use of a switch in the ethernet chain. My understanding is that this is effective as it galvanically isolates the components providing an additional layer of noise reduction? I have an older Cisco Systems Linksys 10/100 5-Port Workgroup Switch model EZXS55W left over from my old home network of years ago. Could this be used effectively? I believe that technology has progressed to Gigabit Ethernet (1000baseT). Will the Cisco switch I have now limit throughput of high-res data? The assumption is that a standard (but good quality Cat6 cable acquired from Fry’s Electronics will run from the Eero (which is connected to the NetGear router via WiFi to the Cisco switch, then a high quality ethernet cable (Audioquest Pearl) will run to the streamer. The streamer then connects to the outboard DAC via the marvelous Black Cat Silver Star 75, so kindly gifted to me by Don (Audiogon user CFarrow). RIP Chris Sommavigo - I am still very sad about his passing. Such a loss to the audio community.. Then DAC to preamp and amp. I further understand Uptone Audio is working on a next-gen Ethergen product which is very interesting.

Any input is welcome. And my thanks 🙏
