Will using an Powerline Internet network extender effect Sound Quality?

Possibly - Ethernet over power lines is the work of the devil and best avoided. I just hardwired my connection with 30m or so of cable around the outside of the house. 

BTB - LAN cables are designed with runs of say 100 meters, with no deterioration in the signal.  Given that, and the fact that you inted to use your network for streaming, a regular LAN network will be your best bet.

My Internet box is downstairs at the front of my house and my system is upstairs at the back I would prefer a wired signal to my ND5 XS rather than WIFI and instead of running 40 or so meters of cable all around my house I was considering  passing the signal over the mains using a bt network extender but will this effect sound quality?

Really is quite likely, as injecting high levels of RF noise onto the mains is usually seen as a bad thing because of the low levels of intermodulation distortion produced in sensitive circuitry connected to that mains. Less sensitive and lesser resolving circuitry will be less affected.  I have certainly had much experience of this over the years. Luckily I found Ofcom very helpful at the time in having the guilty device culprits in my neighbourhood removed, but I did need to demonstrate at an engineering level the interference caused to protected services (which hifi alas is not one). It was a fascinating experience.. especially the stealth RFI detectors they used built into unmarked vehicles.

You're a builder, for god's sake. Get your drill out and do it properly;-)

I didn't notice a difference when I put some of these in, but I did when I took them out!  By then my system was more resolving, but I recall the improvement when removed was significant enough to post here about it.

I'd recommend doing it properly now.  You can get flat cable which is very easy to conceal under carpets etc.

What makes you say that?

I have been running devolo dlan for 2 years 500 mbps and it sounds great. No issues. Having said that i havent tried hard wiring with cat6 as its a fairly large distance from my router upstairs to the living room below

Possibly your forum ID.

I have just orderd a 50m run which whilst I am intalling  my beloved will ask 'why are you doing that I told you I dont want loads of cables all over the house' to which I will answer 'but it will sound better because of the rf interference' she will then shake her head and walk away.  Anyway thanks for all your advice I will let you know if it sounds better.

That's the spirit!

You need to recruit her to do a blinded listening test.  Whichever she picks as better, say it's the new cable.  She will then finally realize that you're always right.

After a house move at Christmas, I tried initially using Ethernet over powerlines as my router comes in under the stairs cupboard in the hallway and the system is in the living room plus there's two PCs in the office upstairs. I needed Internet connectivity for my NDX and the PCs.

Whilst it worked from a technical point of view, it generated a lot of noise, hum and clicks in the system (audible clearly when no music was playing) particularly when the pre-amp was set to Phono.

Took it all out again and things went back to normal. I now use wired Ethernet from NDX to switch to NAS and a wired Ethernet from Switch to wifi extender plugged into the wall. This talks quite happily to the router under the stairs cupboard and streams radio with no interuptions. Same upstairs receives wifi for the PCs

Do we take it that those who experience issues don't have a dedicated supply for their system? 

Is wired better than wifi? If so, why's that then?

I'd used Powerline Ethernet for years. When I got the Mu-so I had problems streaming 96KHZ FLAC. When I replaced the powerlines with wired Ethernet I no longer had streaming problems and there was a noticeable improvement in sound quality.

Interesting! I have absolutely no problems steaming via WiFi to the Muso. I have loaded all the Beatles records to my Synology 212j, which is wired to the router but in a separate room from the Muso,  in FLAC and thought I'd give at least one album a listen this afternoon. I had to use DSAudio to play the music from my iPad as the Audio Station on my MacBook  simply cycled through the tracks and played nothing. Haven't tried it from the PC today.  Regardless, the FLAC files played perfectly with only the long and very silent gaps between tracks a little disconcerting. The Muso is absolutely silent with no mains interference, no crackle, nothing.

Not this girl I'm afraid we live by the simple rule that she is right always especially when she id wrong and if I live by that one simple rule I pretty much get to do as I please its a strange system but it works well.

Bart, you are a genius! That's almost as good as my get her drunk on a bottle of wine and beg strategy

It was not WiFi it was Ethernet connected via Powerline (i.e. over the mains cabling).

I have a Mu-so qb connected via WiFi and that streams perfectly even to 192KHZ.

When first moved into our 1909 foursquare here in Seattle tried power line over the outlets (wiring and box had ben updated throughout) it wreaked havoc on then 5si. I wouldn't do it, but then with an old house you have the luxury of cutting holes, running cable outside, etc etc. It doesn't hurt that the phone in is directly below the main stereo and so I've set up  top shelf in a closet that serves all the network needs with modem, switches, Vortexbox, backup drives, linear power supplies, etc. Run a two meter length up of AQ Cinnamon up to the now microrendu (was UQ) and bingo. But I realize not all have that luxury, and I'm still nee to get to other parts of the house. We have wifi of course, but the more and more I read about it and health effects like to plug in as much as possible. 

Anybody tried adding a Moca adapter to existing CATV wiring?  I never had to, but seems similarly easy as powerline adapters.
