Mains extension blocks

People have different preferences and are free to choose which suits them best.
I started off with my two naim leads into seperate unswitched sockets then tried the old two leads into one plug and liked it better so it stayed like that for a few years.
Bought a hicap dr and needed an extra lead so then purchased a chc hydra but didn’t like the build quality so quickly ordered a grahams hydra. Wasn’t keen on the hicap so it went back to the dealers but surprisingly i preferred the grahams hydra although i’m only using two out of the three leads.
I ocassionally try going back to the old two leads into one plug in order to tidy up the mass of mains leads under my rack but it doesn’t work for me and the grahams hydra is always quickly returned. So for me garbage is the way to go.
I haven’t tried powerlines as refuse to spend over £1000 on two mains leads but if you have the cash to burn and think they offer a worthwhile improvement then go for it.

If this has been put into action demonstrating Naim devices with those large Focal speakers, no wonder many have been put off with those large Focals. Those superb Beryllium tweeters and sandwich drivers are going to tell everyone that they have been mother fed from a plank of wood and plastic.

Maybe what many here and Naim themselves are in need of is a Super lumina mains block, ( configurable between 4 to 10 outlets) and of course super lumina mains cables.

Glad it worked out well Jim. Now stop messing and get listening :grinning:

After reading this thread I am now looking at my MK- 6 socket block with surge protection :open_mouth:

Spotted this MCRU 6 WAY AUDIOPHILE MAINS BLOCK | LAPP CABLE | SILVER PLATED PLUG

Does anyone have any opinions on this mains block, it is very reasonably priced.


The LED has been disabled

:small_blue_diamond: EazyRyder,…My simple advice is,…Avoid surge protection and mains filters.
It hijacks transients,and makes the musical presentation more “laid back”.

Well I have gone ahead with the purchase.
It doesn’t have any filtering and no surge protection, looks a good quality mains block.
Plus the LAPP power cable will match well with my QED Genesis silver spiral cable :ok_hand:

I have the non silver plated version with a Powerline Lite mains cable connected to it. I’m happy :grinning:

Clearing the wall socket for the hifi worked well.
As regards the long cable for the ‘other stuff’ it’s a bit of a struggle.
I have bought a Wireworld Matrix 2 and a 6M kettle lead, but I sent the kettle lead back because it was making the TV picture worse - a very low quality lead I think. There wasno description of what it was even made of.
For the moment I’ve daisychained bog standard extension leads together - but these have into one socket:

  • router
  • Cisco 2960
  • Samsung TV
  • Samsung STB
  • Humax STB
  • link box to upload solar panels data to the net

Too much I think! Probably unsafe.
So should I try another better quality long lead?
Will all these 6 items go ok into one block?

You could try the TV into one of the wall sockets instead, for a better picture. Then just take it out when critically listening.
6M of quality mains cable won’t be cheap. Might be more cost effective to get an electrician install a closer outlet.

For general purpose power extension leads & the devices JimDog has on it, a 1.5mm or better a 2.5mm cable is perfectly OK. If the TV was not happy I doubt it was the extension cable, more like a bad connection in the power outlet block.

My important extension cables are Lapp 100 CY 2.5mm cable & a home brew power block with MK sockets. And at something like £5 or £6 a metre, it can’t be beaten for quality vs price.

Jim - I’m not sure why the TV was giving you problems - worth checking the connections as Mike suggests. For those items and as you have the Matrix block, I’d buy an IEC plug (C13 type) and nip down B&Q (other DIY stores are available) to get a suitable length of 13A mains cable and a mains plug and wire that up.

That’s a fair ‘cop’…
(Your invocation of Godwin’s Law, I mean - not the bloke on whose dodgy haircut that graphic is based.)

Good idea - except then I’d have to listen to the TV through its own speakers.
Yes, I’m talking to an electrician anyway because everything in that room - including my daughter’s lava lamp - is all on the same ring so will be degrading the sound.
Meanwhile I have ordered a 7M white cable with a right-angled IEC for about £18 from t’river - about twice the price of the nasty cable that went back - so must be twice as good!

Thanks for that info, Mike.

The one I’ve ordered is described as:

  • RIGHT ANGLED IEC C13 SOCKET - These connectors have 3 holes and are classed as female IEC sockets even though they are usually plugged into a recessed C14 plug
  • 3 x 1MM² ROUND POWER CABLE - 10A Rated 90° IEC C13 Socket with 250V 3183Y 3 core Earthed Cable to a standard 3 pin Fused 13A UK Mains Power Device Plug

I’m not sure what they mean by 3 x 1MM² ROUND? Does it have 3 conductors in it each with a cross section of 1mm²??
But I’d be better off buying the bits and making it.

3 x 2.5mm² would be better, MK plug and 13A fuse. You should find a rewirable IEC 13 socket of RS or Farnell.

Yes that what I read & highlight/www/search on that shows you bought it from electricaldirect co uk. I hate to say it, but not what I would choose. I would always got with 2.5mm 3 core.
If you do intend to fit an IEC320 (C13), you need to look around the higher end vendors as the one you have chosen will probably only accept a 1mm cable.

To give you some bench marks:
The standard Naim PowerLined Lite cable to power an individual Naim unit is 0.75mm
Most 3rd party cables sold to the audio market are 1.5 or 2.5mm
Naim’s full-fat PowerLine is 4mm

Thanks Mike and others - the order is cancelled.
I’ll make a good cable for it.
Jim

Have a look at www / MCRU & consider the item shown as AUDIOPHILE MAINS LEAD LAPP CABLE, you can add extra metres. Also look at whats available with the selections of cables off the reel & the various plugs & sockets & for you to DIY

At the moment I’m running my Cisco switch using a PC kettle lead that has been in my damp garage for 20 years.
If I was going to get an inexpensive power lead for that, would half a metre of Lapp cable be suitable?
