Mains Re-wire

[gingersmarty]

Hi all,

I am about to rewire the house, well somebody qualified is! Is there any mileage in

considering my set up in this? Would a dedicated main help? It would be extremely

cost effective as every other cable is being replaced. if felt to worth it any would specialist

mains cable be worthwhile?

Run would be about 5m and i am not into kimber prices.

thanks

Yes yes yes yes yes!

A dedicated spur is pretty much the holly grail of AV / hi fi mains. Can't comment on the RA / Kimber products, but most seem over priced.

Do your research though. I have a dedicated spur but didn't get a separate consumer unit so may have fitted. Something like this. Talk to your sparky about earthing, earth spikes, switchless sockets etc.

You'll probably never have this opportunity again so do it right. The extra cost will be minimal and nothing compared to the daft prices you can pay for various mains products.

And while you're at it get an ethernet port or two installed as well.

Absolutely worth it, as stated above, ideally the incoming supply to the house is split going into two consumer units. Make sure the HIFI raidial/ring is the first in the line.

Silver plated consumer unit such as this, then 6mm squared twin and earth cable (basically the thickest you can get into and out of the back boxes) any type good enough but you could use some of this to wire from it to the number of switchless sockets you want to go for one for each bit of kit.

Hope this helps

Another thumbs up from me, I installed a spur last year using Supra LoRad 3.5 and some switchless sockets with a earth connections from RA. The Supra was around £100 for five meters of cable and the sockets about £30 I think. Well worth it overall, less noise from the kit which resulted in a much quieter presentation from the speakers.

Thanks to all for the replies,

I have loosely discussed with the sparky and he didn't look at me

as though i was bonkers, i will discuss further as regards an additional consumer

unit and mains cable, however i am leaning towards installing this, probably cost less

than a decent interconnect.

I am completely clueless around the benefits of a decent earth, can someone explain

using language from the " Big book of Earth for beginners"?

Regards

Earth in the main consumer can "float" by a certain percentage so the value will not always be zero. If your kit uses this as a reference then everything will be affected.

A seperate clean earth purely for your HIFI ensures that this Z value stays as close to zero as possible.

Good clean earth = nice quiet non music parts background noise reduction

That why much of my kit hums?

Roger, yes but also that Naim tend not to worry about transformer noise in their designs they focus purely on performance.

My Hicap 2 hums like a swarm of bees at times!!

Thanks all for opinions and links

I'll discuss the earth set up with the sparky.
