Problems streaming super hi def music

Posted by: david deakin on 24 December 2012

Having upgraded from Cyrus to Naim (following a Naim factory tour) with a SuperUniti I bought some music from the Naim label - Meet me in London - 24 bit at 192kHz. It sounds wonderful, playing from a USB drive. However I have tried to stream this from a NAS using wifi (BT Infinity) and then tried ethernet mains network adapters (200bps). In both cases the music played for 16secs and then stopped for 3-4 secs - repeatedly! All CD ripped music has been fine. So as a newcomer to streaming is it possible to effectively stream super hi def music? Unfortunately getting hard wired ethernet is difficult due to the locations of the router and the SU being far apart. Is it worth trying 500 mps or even 1gb mains network? Or do I need a better nas? Any advice from anyone who has streamed this super hi def music?

Hi David,

 

My guess is that it's the network, not the nas / server itself.  I can reliably stream 24/192 over wired ethernet.

 

Many folks will tell you that it's pretty guaranteed to be unreliable to try to stream those files over wifi.  I am not experienced with the ethernet over mains hardware, but I suspect it's not robust enough either.

 

Especially if you can return it if it doesn't work, try better-rated ethernet over mains adapters.  Maybe you will get lucky!

Hi Bart

Many thanks - yeah I'll try faster mains network adapters

You can always place your NAS near your system, and connect it through a simple ethernet switch. NAS > Switch > SuperUniti with short runs of ethernet cables. If you need the NAS on your home network, you could get a Wifi base station, ether connected to the switch or built into the switch. this way, the NAS > SuperUniti connection is still wired. Lots of options.

 

a "cross over" ethernet cable should also work to connect the NAS directly to the Super Uniti.

Hi, yes you need a wired Ethernet network. I am afraid mains Ethernet adapters are  half duplex (single collision domains) and don't have the bandwidth (as well ashaving a host of ther issues). Wifi again isn't really designed for this sort of thoughput and again is unlikely to be able to supply the bandwidth. Wifi (in most installation) is  also half duplex. Regular wired Ethernet is full duplex and is good for 100Mbps at least in both directions simultaneously. Hidef audio is trivial for wired Ethernet.

I had exactly this issue, and even going to Devolo 500Mb/s powerline ethernet-over-mains wasn't enough (as S-i-S details above).  Only answer was to go for wired Cat5e in house.  Thought it was going to be a big deal and involve lots of drilling, holes, brick dust, etc., however a friend (who installs burglar alarms for a living) wired the lot up in 90 minutes - no mess or fuss!

 

The other benefit is that I'm no longer contaminating my mains with RFI or other noise via the Devolo powerlines......

 

It's taught me that Installing wired Ethernet may be easier than one thinks.

If you are stuck to wifi you might also consider convertig the files to 48/24. This is something I can stream via wifi without any problems or dropouts.

I keep the higher res files for later use of course. 48/24 is still very good and in any case better than not being able to listen to it at all.

Just confirming what everyone else has said. I had the same issues trying to run via Internet over mains, and finally gave up and moved my router close to the SU, enabling wired connection. Since when, no problems at all.

Hi Guys

Many thanks for your replies over Christmas - really appreciated. I'm going to try Mutterback's suggestion of using an ethernet switch? to enable the NAS to be directly connected to the SU. Otherwise its wiring the whole house as George has done or seeing if I can change where BT Infinity router is sited. In terms of the ethernet switch or 'crossover' where is the best place to get these - PC World?

Try somewhere like on-line store (e.g. the one that starts with an 'A' and ends in 'N' and sounds like a jungle), as PCW very expensive.

 

I ditched my home hub 3 last year (too many issues and only had one Gigabit socket) and replaced it with a Billion Bipac 7800N modem/router.

 

I also use Netgear Gigabit switches (e.g. GS-105 & GS-116 Prosafe), depending on number of sockets you need, and have had no issues whatsoever. If you do a search, you'll see Phil Harris from Naim recommends Netgear switches.

 

Believe me,it'll be worth the effort when you are able to sit back and listen to your Antonio Forcione with no gaps or pauses..........

David for clarity if you you are using a switch to plug you NAS and Unitiserve into you should use standard pass through patch leads and not crossver leads. Although most switches will self configure it's best to get it right for fustration free performance.

Success! I tried both suggested solutions from Bart and Mutterback. Upgraded from 200 to 500 Netgear powerline and bought an Ethernet switch so now connecting SU through the switch to the NAS. Now streaming 192/24 no problem! Thanks for everyone's help - much appreciated.

David glad you got it working .. You can't beat wired Ethernet
