Move router far from hifi components?

Adding a LPS to the modem/router hub for WiFi streaming has been a surprise revelation. Essentially, it is the source to the source. I’ve now auditioned 6 different power cords - each with a different sonic signature. More or less, each one maintains its sonic signature as when plugged directly into the streamer or DAC’s LPS. Yet, IME, that sonic signature seems to be even more pronounced when used on the LPS for the modem/router - kind of like on steroids. Only auditioning will determine what PC works best for your system and your ears. My system is relatively hi-res - very sensitive to cabling and power. When I auditioned a Sablon Robusto with the modem/router LPS, it was if my rig just downed a triple shot of expresso. Way too intense!

Within my budget, I’ve been very satisfied with the regulated 12vdc power supplies made by Astron: Astron RS-4A or Astron SL-11R - using this copper wire and this connector to make an umbilical cord. Voltage can be precisely set to 12vdc by dialing a wheel found under the cover. Used Astron’s can easily be found on Ebay. Avoid the ones with the captured power cord. Get those with an IEC inlet. You can even upgrade the fuse, if you wish.

Steakster, thanks. I have also found improvements with a better ps to the hub. Currently this is by Sbooster a Dutch company. Also works well with the Lumin D1 player.

As regards something even more exotic, I have been in touch with Paul Heynes and he has confirmed he is still making power supplies. He sent me a long list of various types and options, prices ranging from about £300 to £1800. The more expensive options include silver wiring and dual rails for better SQ. I have heard good things about Paul's power supplies.

There are a lot of great LPS available today I just chose the W4S for their versatility , the ability to hook up 4 different units instead of using 4 different wall warts or 4 different LPS, Currently the one W4S comes in handy powering my FMC, Aqvox switch and Optical TV line. The 2nd W4S and mentioned previously handles the router. I have found its very important and effects the SQ having high quality Ethernet cables vs the standard cables supplied from the Manufacturer like the basic PC from manufacturers are cheap and effect the SQ of the overall system. Mike Lavigne once stated, once you reach a certain level in a high end system the improvements are small but so important to the overall SQ. Boy is that the truth. Every little step regardless of cable, PS, isolation, room acoustics ,component makes an improvement. My system is Ethernet based and high quality Ethernet cables have definitely made an improvement .
I would very much like to get my hands on a Paul Haynes PS one day as Im sure they well further improve upon the SQ in any high end system.

In regards to the router being in a separate room my access point ( router are in the same room just 10 meters from my system and on a different power line, I have an isolation transformer running my system with digital and analog on different dedicated lines. 

I have found from reading about this on CA that running Ethernet with optical ( Isolated lines ) have made a huge impact on SQ and highly recommend it with anyone using an ethernet based system.

I realize this is a conversation from a couple if years ago, however, I just read it for the first time recently and decided to see if some if the advice contained within would help my system and I can say that it most certainly did. 

My WiFi modem/router is still close to my system rack, but I moved its power cord and also a couple of other various switching power supplies for the cooling fan, Roku and Aptx Bluetooth receiver I use when I am looking for something new to add to my Tidal playlist to a separate power conditioner I had  and plugged it into a separate outlet and I am very, very pleased with the results. 

I may try an isolation transformer later but I am really enjoying this essentially free improvement.
