Network Switches

@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!

“If you want to eliminate any noise into your streamer or dac, convert the Ethernet to fiber then back to Ethernet at the streamer/dac.”

@rbstehno , @deep_333 and anybody else who knows,  I’ve been thinking about trying this, as an empirical experiment. In my case, I’ve got a cable modem capable of 2.5Gb speed, but my ISP tops out at 1.3Gb, going into an eero 7 which then connects to a standard unmanaged ZYXEL switch, which itself is connected only to a Roon Nucleus One and my streamer/dac (all integrated into my NAD M33), which has an iFi silencer in its port.

So, as i don't have or need 10Gb capability, do i need anything beyond 2 media converters and a length of 1000 BASE-LX or SX fiber cable?  And is LX (single mode) necessary —or better - when the run will be less than 1 meter?   Assuming SX is fine, do these converters fit the bill?

Anybody have recommendations for fiber?

will this do the trick?

Thanks very much @deep_333 ! 

I found what i hope are equivalent devices on Amazon (bowing to tax, shipping and return issues). I’m going to try this out.

I’m also tempted to do this for the reason @erik_squires mentions. I could build two “moats”: one between modem and router and then one just before the M33.

good listening, everyone!
