RKR used to recommend getting in contact with your electricity provider to install a 100 Amp main fuse on the basis of installing power showers and normally they would oblige…
Unfortunately I extended above the garage, and that extended loft space is a sort of plastered room, so cant feed through that, however this thread has got me thinking of other routes. In reality I would probably just go 1x10mm into a double socket, then use my Mains block. Actually I think MK do a triple socket also, although probably not un-switched. Anyway there is a light bulb above my head know - let’s hope it doesn’t shatter.

If it helps I had to replace my old dirty 20 year old crabtree (the recommended socket at the time) switchless sockets for shiny new metal switched sockets in the new extension for cosmetic reasons (matching) and wife pressure and found that practically it made no difference to the SQ. Also the added advantage that I can switch off at the hifi end for occasional maintenance rather than running the length of the house to the CU to find I’ve switched off the wrong component

Hi from Sweden, I have just installed my third dedicated mains. I measure the phase (we have three phases) with lowest usage when “all appliances” switched on, I then install a Klangmodul automatic switch box, good wire (Furutech 16 mm2 outer diameter, shielded), shield to ground at box end, then wire to 1 Furutech dcf outlet. Then Audioquest Tornado to Audioquest Niagara 3000. Sounds great! Quiet, dynamic and beutiful! Same impact all three times.

If the wall is plasterboard, you could cut a channel and re-skim afterwards or go over the ceiling or under the floor

I’ve never installed 10mm armoured before, but looking on Screwfix(UK), it comes in 3 core. So would the outside steel armour be bonded with one of the cores, in which case that gives quiet a decent earthing connection, which presumably helps a lot?
Update: Just checked, from what I can see the amour steel does also connect to earth via a banjo connection (or similar) as well as one of the cores, so that should help effectively give a really good earth connection, which Naim gear loves
Does it need to be armour plated (as long as it’s in trunking)?
You can use either, although armoured cable is usually easier. Running properly installed, sealed conduit is more work, then you’ve got to pull that stiff 10mm cable through it. But your electrician will know that!
Anyone recommend an electrician for this sort of work in the West Midlands? I’m just NE of Brum, in N. Warwickshire. My installation would need to go right round the outside of the house. Our lounge is a single storey extension that doesn’t have any access to the roof space.
It should be fairly straight forward for most electricians, as they will being this sort of work quite often when they supply power to a garage/shed/out-house.

The electrician I use is excellent, and has experience of installing and fault finding “quiet earth’s”, or whatever they’re called, for computer rooms. He can also install dedicated earth systems, although he hasn’t done mine yet. He’s a great bloke, but he still thinks I’m “f****** mad” 
He lives near Cannock Chase and will travel. PM me for his number.
Thanks, Spanna. I’ve temporarily put my email address at the end of my system details in my profile. Can you email with the details, please? (There’s no PM facility on here.)
(I’ve also tried to message you via PFM - if that’s the same @Spanna!)
Yes they do. I’ve 3 triple mk unswitched sockets (linked) but have used 6mm cable

With good results??? I am considering doing the same…
MK do a 3 gang socket, switched or unswitched. Either way, it will be fused, which may make it less appealing.
Now that’s interesting, as I’m sure they never used to be
They’ve been fused for as long as I can remember. I’ve got one on a ring main that’s at least 20 years old.
As far as I can hear yes. It’s been done for approx 25 years now but is a ring (dedicated 32amp). I could take the return cable out and it would then be a radial just as the diagram as posted here but I’m quite happy with it as is!
Just be careful a lot will have you believe this and that some differences will be ‘placebo’, if you know what I mean. The same reason a lot of posters wouldn’t dare be submitted to a ‘blind’ listening test for any hi-fi changes. Like all things in this hobby it’s diminishing returns! The main thing, enjoy your music!

I dont see an issue with a dedicated ring, as you are getting twice the earth conductor, so would be inclined to keep as is.
Thanks, I probably will as it sounds good to me!
