Move router far from hifi components?

Had exactly the opposite experience re: distance of router/modem when using Ethernet connection to streamer. Started out with r/m in laundry room far away from my listening room using new 75’ generic CAT6 cable from r/m to Aurender. Sound quality was meh and lots of dropouts listening to Tidal.

Moved r/m to listening room with 1 meter Purist Audio Ethernet cable and sound quality was night and day better. Even when using a 1 meter generic CAT7 Ethernet cable the sound was n&d better than the long Ethernet cable, just not as refined, clean, black and extended as with the PA cable.

Wallwart p/s and power cable from r/m was carefully isolated and plugged into completed isolated AC receptacle/circuit as I believe that Erik nailed it re: the power supply being the major source of noise.

I think it is true. You should try this.

I keep my router in a room upstairs. It is very far from my audio system and I use wireless to access much digital music. I have a cd player and DAC when I listen to CDs. I have power strips (hospital grade) and low noise which are pretty far from my components. This setup is the best I have found for sound. I have zero power conditioning, but my room is acoustically ideal for the type of music I have and speakers I use.

To Randy's point, I keep my computer audio front end and router/modem electrically isolated from and around 10+ feet away from my analog gear using 20' long XLR IC's from DAC to preamp.

I got better sound using wireless than from a long Ethernet cable. Can't really buy that with all of the RF from phones/wireless devices shooting through the air that the location of the router/modem (to avoid RF noise) is that critical. As stated before, it is more likely the noisy power supplies in consumer computer-related gear that creates the sonic issues and that can be managed. YMMV.

Are you suggesting to buy a linear power supply for the router instead of the wall wart?
