Ethernet switch worthwhile?

I know that reducing noise for both analog and digital devices leads to better audible performance. I remember 40 years ago Jacques Riendeau from Oracle coming to demonstrate his new external power supply for his turntable - absolutely an improvement in sound (how could this be, I thought?). Almost all of us have devices with external switching power supplies of various voltages and quality of manufacture. If you can replace those wall-wart power supplies in your audio system you will hear improvments on both streaming and analog playback. A better switch with a linear power supply offers better sound, isolating your audio system's wired ethernet connection from the rest of the house's network gives improvements in your digital audio playback. Use something like an iFi https://www.silentpower.tech/collections/enhancers/products/lan-ipurifier-pro or an ADOT to do this. Have a look at the DC linear power supplies made by KECES Audio - the P6, P9 and P14 models. Or the Plixir BDC mk2 DC power supplies. 

@fastfreight--What is to understand? He asked if a switch was worthwhile and I said no. Please conduct a statistically relevant test with / without your high priced switch and get back to me. Please explain how this switch can produce a sonic benefit to your highly resolving system? 

Instead of feeding into the audiophile insecurities that exist, I suggest spending his/ her money on something that may actually make a system sound better.

Did you try your switch with a linear power supply? 

Is an audiophile ethernet switch worthwhile?  Why yes, everything (improvement/upgrade) is worthwhile!!!  Get the best switch and ethernet cables you can afford, as they do make a noticeable difference (in my experience they do).  Happy listening.

I’ve found that optical isolation before your streamer (N10) is one of the most effective ways to clean up the Ethernet signal. You might want to look into something like this ⬇️, for a clutter-free setup.
