Guys

Just looking at recommendations for speaker cable (for my own house as the first fix is coming up)

There seem to be a number of grades and prices!

Thanks

I used this https://www.tlc-direct.co.uk/Products/CASPEAK79.html and it is quite a heavy cable I have a 5 x 100watt amp, to be honest if I plug a cheaper 42 strand cable into my speakers and then a 79 strand, I cannot hear any difference!:) There isn't a great price difference between the 42 and 79 strand at TLC about £13 per 100m. You would probably notice the difference between these if you had a really powerful system or a really good ear!;-)

As Roly say's really. I installed speaker in my home and installed the heavier stuff but I doubt I could tell you the difference.
I suppose that if it is a long run though the heavier grade makes sense for volt drop. Couldn't tell you how much though.

How long is long? The longest run will be about 14 meters!

You won't notice any difference in a blind test! Professional audio installations often use standard singles and nobody can tell any difference with the super oxygen free interdimensional cryogenically doodahed cables
 
I have used twin and , flex and bell wire , gold connections or cheep tined connections and not noticed the difference ,

or just use up some leftover cat 5.double the cores up.
The CSA is too small for my liking, unless it's 100V line.

But then when anyone says speaker my mind jumps to the big heavy *******s we use for gigs and suchlike.

on a touring PA system you will have a heavy duty H07 cables with something like 2.5/4mm csa. does the job for even the biggest amplifiers...
1mm cable will be more than enough for any home hifi. dont need to be gold oxygen free audiophile type one, standard two core multistranded flex will do. stick some bootlace ferrules at the ends for nice terminations.

NEVER use T&E. For distributed music systems 1.0mm strandard double insulated. Good for up to say 30m runs 100v line with a 120w amp. 1.5mm if you are using lo impedance up to 500 watts and less than 20m
Why not?

Mechanically, old T&E easily breaks if amps are moved e.g. in an office.

anything that interrupts the crap shoved through the airwaves by the likes of radio 1 has got to be a good thing.
 
Not really. We have done a few where the guy has wired himself (10 rooms with one cable in each) then plastered and painted, and THEN comes in for the amp/speakers. Most systems we do for Sparks are 100v as they are commercial. But same applies to domestic. A good OFC 1.omm will do most systems. The hifi fanatics do believe in 6.0mm harvested at midnight gold dipped 2000 strand 'one way only' cable marketed in expensive magazines, but what else do they spend money on? Plebs like us can't hear any difference. If it needs to sound great, spend dosh on the speakers. Yamaha do amps good enough for most of us.

NEVER use T&E. HF travels on the surface area of the stranded copper so using T&E limits the surface area.
There is really no need to shout, can you back up your point with something more than just a brief description of the skin effect?
Whilst the skin effect exists you won’t hear a difference in a home audio system.
Doing a quick bit of research I’ve found that generally the limit of human hearing is around 20kHz, at this frequency the radial skin depth in round copper conductors is around 0.4mm which coincidentally approximates to the diameter of 1.5sqmm solid conductors. So the effective depth of the conductor used by the audible frequencies is all of the conductor.

scratch music is correct

much in the same way as we use braided or better still braided strap and not solid for RF grounds as it travels the surface and Braided wire has more surface area than solid
It’s not the same as RF is at much higher frequencies than audible frequencies so the skin depth is far less and braided cables become necessary, for audible frequencies the effect is negligible

FYI - I did the cabling in the spring of 2016 - not found any money to add the surround sound as yet...

that would depend on the power specs of your amps and speakers.
generally you want to go with heavier cabling to prevent voltage drop,
preferably with a higher strand count and tinned or gold clad contacts to minimize oxidation
You can also tin your conductors using a good quality silver bearing solder.
Yeah, all this tinning and gold connection stuff made a huge difference to my 30 year old two channel stereo system...

In a domestic set up there's no requirement for expensive wiring systems unless the audio equipment runs into the £1000's...
 
Amps have changed since my Mosfet days ,have digital amps made it yet ? ( or are they just a way of upsetting your local HAM) ... any differences in speaker cabling ...
 
I know the digital gear messes with my pager (fire department) so it sits in the charger base while at home.
I use regular scanner in those areas.( or rather centralized scanner and remote speakers)
