Where in your network can you site the NAS?

To be honest I'd leave all the commercial electronics as far away from the Naim kit as possible. My NAS is audible (moreso than the ubiquitous transformer hum) plus all the PC kit can be fed from a surge / brown-out protected supply.

Make it your mission (impossible) to rid yourself of the Devolo stuff. Get handy with a crimping set and a big drill if necessary. Do it, no excuses now.

I have a finished basement in my house where the internet router is located in a room that I use for watching TV. I  have the NAS on a shelf connected to a Switch which is connected to the router. I have a (approximately) 40 foot cat5e ethernet cable running from the Switch up to the first floor living room connected to the NAIM streamer.

I have a MAC desktop located in the TV room downstairs that I use (dBpoweramp software) to RIP CD's to the NAS. iPad located on the coffee table in the living room upstairs controls the music selection with the NAS blinking blue lights and very light hum on occasion safely and quietly tucked far away physically from the stereo system.

The basic network topology is alwasy the same: all your networked components get connected to a switch (in your case your router is acting as a switch).

Ethernet cable runs can be as long as 100 m (for CAT 5e) with no degradation is quality. So that gives you a lot of flexibility in placing the network components as you see fit. The ‘only’ constraint being hiding network cables.

The basic network diagram is like this (picture courtesy of Mike B)

As do Devolo - Internet-over-mains is best avoided for high-quality streaming. Mains introduce far too much noise and signal degradation.

I have mine in an upstairs study connected via a 25 metre cat cable from the switch which is in the lounge. The powered switch ( a Draytek) is in the lounge but plugged into a different radial circuit. I use the QNAP as backup to my Core which sits in the equipment rack. The Core has an SDD drive which is silent. It also has a linear PS which makes it ideal to sit on the equipment rack. I avoided mains over the Internet for reasons stated bt Adam and others. For those of us with Sky Q boxes it’s worth turning the internet over mains function off as the installers leave this on. I also use Ethernet connections on said Sky boxes. It’s quite easy to configure using the hidden menus. I tend to run the Ethernet cables through white micro trunking along the top of skirting boards - it’s very neat and blends in nicely.

I have one of mine about 50cm away from the renderer. My other one is 200cm away.

Although I have been known to stream from another country. For example, from Switzerland to the USA.

Thanks folks.  Very helpful, and I now have a project on my hands..!

Happy Christmas.

I had a problem with my router positioned a distance & a very difficult routing via walls & roof cavity distance from where the audio was located;  I had the phone company move the incoming line access point (plus remove all the old extensions & fax/telex line - all extensions are bad bad for www line speed)   The best £130 I've spent as the router is now located were I really want it,  near the audio,  the TV is now ethernet wired & the study works just fine over wireless.   

I now have the NAS in a cabinet (silent & no flashing lights)  the cabinet also houses the UPS & switch & the router sits on top.  This is a 4 meter ethernet cable distance from/to NDX.
