Network Switches

My advice is that switches upstream don't matter.  Bad power supplies do.  

Keep your networking power supplies (i.e. wall warts) off your clean power area.  Use a separate conditioner if you need to, and consider using iFi power supplies for them if they are near your audio. 

Also use shielded IC's and power cords (the cheap shielded, not the expensive shielded) to avoid noise pickup.  I like to make my own from parts at Parts Connexion.

@erik_squires, if you have a second, along the lines of this discussion of switches and power sources, can you tell me what you’d recommend i do about power supplies?  I have an NAD M33 that serves as integrated amp and streamer & DAC. It is Ethernet cable connected to a basic, unmanaged 5-port switch (ZYXEL) and the switch is Ethernet cable connected to my Roon Nucleus One and my router  (Eero 7), the router is ethernet cable connected to the cable modem (Arris surfboard S33).  All of the cable modem, the router, the ZYXEL switch and Nucleus One are, at the moment connected to an AudioQuest PowerQuest 505 (outlets in the non-High Current sections) with their manufacturer provided power cords and power adapters/wall warts.  (FWIW, the M33 is connected to the High Current section of the same PQ505 via a new Audio Envy “Expanded Ocean” power cable.) 

(Speakers are DALI Epicon 6s.)

Would you recommend that I get the network items off the PQ505 and put them on their own conditioner/surge protector (E.g., a PQ303)?  (I had been thinking that the PQ505 would do a good enough job of separating and killing any noise or other interference, but now you have me questioning that assumption.)

Many thanks!

@rivinyl is there a reason why you need a switch at all? 
In my opinion, invest in a better ethernet cable first. They make a difference.
You can also pick up an iFi LAN iSilencer on amazon and combine it with a better cable. I wouldn’t waste money on a $500 switch. Unless the switch reclocks the signal and throttles the output at 100mbps and your streamer prefers that speed. But now we’re talking $1000+ for a switch which to me once again makes almost no sense.
