Powerline adaptors - wired network and Uniti

Are your walls insulated?

Solid brick, Victorian - with modern wiring.

Hi Tog,

Not sure but wouldn't an Airport Express do what you need?

Anyway, I have used a powerline with my Uniti and for me, it works great. Never had an issue. I use the Netgear brand for my router, nas, powerline.

How do you organise you connections to the Uniti and the NAS Develyn?

Tog

Hi Tog,

NAS connected to router via Cat5, Uniti wireless to router.

*I normally don't use the Powerline as my wireless connection is consistently stable.

Has anyone tried it and would I just link my main Airport Extreme to a Powerline adaptor or the Imac with the music files?

Tog, Powerline adapters (PLA) can be bad news for sensitive hifi. PLAs induce a massive amount of RF energy into thebmains wiring than can produce a whole amount of inter modulation distortion in hifi and other devices. This can rob sensitive or detailed hifi sounding any where near it's best. The other issue with PLA is that even a close neighbour even on a different phase can cause issues with your HiFi if they are using PLA and you are not.
Finally some of the newer highspeed PLA can affect FM and DAB broadcasts and reduce the signal to noise ratio in your ADSL feed - all depending on the nature of the cables to and inside your house. If your mains wiring is unbalanced and most are the PLA turns your house wiring into a wideband radio transmitter antenna, again all this RFI is not good for Naim or other devices. Indeed Naim state in their instructions it is important to keep RFi away from their devices due to the sensitive high bandwidth nature of their electronics.
Best solution is cat Ethernet cabling, followed by wireless. You can get repeaters for wireless.

I use Netgear 200 Mbps powerline adapters (XAV101), and have no problems streaming (speeds of >80Mbps indicated). Sound quality is fine and there is no interference. My wiring is 40 years old.
There are some situations where manufacturers advise it may not work very well, like when your two plug sockets are on different ring mains circuits, so it might be worth reading up on that.

I don't have any experience with Airport Extreme i'm afraid.

There are quite a few posts where this has been discussed. e.g. Uniti streaming and powerline

I am thinking of using an Airport Express as a bridge to my new HDX, but am a bit worried about the power supply in it causing problems with the mains. Anybody any experience of whether the SMPS does cause problems (system is 252/300).

Oscar, although dirty SMPS can be bad in my expierience, they tend to be very cheap wall warts, some cheap and not so cheap flat screen TVs and cheap PCs.
I did use the Airport Express on the same mains spur as my Naim and other brand equipment and never expierienced any problems such that I have described elsewehre that I got from PLA and Plasma TVs. Also the airport express has fibre digital out rather than electrical, so if you are feeding a DAC there is one less path for noise to get carried into your Naim.

I did find the quality - I assume down to jitter - of the aiport express rather disappoinitng, and even the nDAC I was borrowing at the time couldn't really totally transform the sound. However from a usability point of view it couldn't have been easier - just make sure the airport express is on the same subnet as your iTunes server -which I suspect for 99% of home LANs will be the case.
