Yes and the Furutech that I have in my AV. Don’t know your point, yet again. I don’t work for Naim.
Naim use a low torque setting on all screws on Powerlines. If you overtighten those on the wires it will spay them and result in a worse connection. This doesn’t happen if you stick to the correct torque, so if you’re going to do it, get a torque screwdriver.
Yes correct, but don’t use a torque wrench, just look at them.
I was only pointing out you didn’t like this but prepared to accept it elsewhere.
In your plugs.
I’m not going to make a one-piece copper part for my power-line that cost £650 and cause insurance problems. No one will ever know about the consumer unit, because it was done so perfectly.
You should just use an MK Toughplug it has one piece everything’s inside and the same material pins.
I’ll do my electrical by regulation not snake oil.
Leave plugs hanging loose for better sound.
I’m wasting my time.
Ferrules are mainly intended for use on Class 5 (flexible) and Class 6 (extra-flexible) cables to:
- Help reduce the risk of “dropping strands” or accidental shorting between terminals (one reason for their use in control panels, especially “hot swap”, as Class 5 conductors are often used in this type of equipment).
-
Help prevent damage to strands in maintenance, testing and fault-finding (another reason for their use in control panels)
-
“Convert” the Class 5 or Class 6 stranded conductor into a “solid” conductor for terminals that are unsuitable for Class 5 and Class 6 conductors.
Whilst I can see that ferrules may be of use for stranded conductors (Class 2), and these are not precluded, I don’t believe any manufacturer of ferrules expresses their suitability for solid conductors with less than 7 strands.
To avoid inappropriate separation or spreading of individual wires of fine wire conductors, suitable terminals shall be used.

Correct, eu version with furutech schuko
Burn in exists! I fully agree
That may be so, in that case my ears are simply not good enough…
Sorry to the op but I hope don’t mind this question .
Is there a reason that soldering the wires at the end of cable that is inserted into the live neutral and earth is not good , legal or otherwise .
I don’t mean soldering the cable into the plug , but basically tinning the loose end wires this becoming a single thick entity which is then squashed by the the screw in the live neutral earth pin .
Are there negatives or illegal implications of doing this .
Soldering mains cables is generally considered unsafe because solder has a low melting point, and if a cable should overheat it could melt. This can cause damage to surrounding materials such as insulation, and may cause contact between live, neutral and earth cables via molten solder.
That makes perfect sense , thank you .
Because lead is a poor conductor.
……having said that, I’m not aware that it actually contravenes any safety regs to use solder, but there are enough reasons why it could cause problems that I would say it is still a bad idea.
Tinned ends to a cable isn’t really using solder as a joint, and given the small amount that would be used, and that there is effective strain relief elsewhere, I can’t see it being a problem. I’ve seen tinned cable ends used in sockets before that were presumably done for ease of insertion during manufacture, so maybe on that specific use it’s not such a bad idea.
Furutech plugs are shipped with a warning that the mains wires should absolutely never be soldered and must only use pressure contact. I’ve thrown away the last box I had but I am sure they mentioned something about US NEC safety conformity regs in this regard. The last plugs I got were supplied with pure copper ferrules which were indicated as optional.
That said, on the other end, it is quite common to see mains input soldered on the IEC inlet of a lot of products.
The only rationale I can think of is that the risk of heating to melting point is really only likely at the plug end where a silly person may have plugged in a bazillion high current things to a single socket. Whereas at the product inlet end, the current draw is never going to reach sufficient temperature.
To be honest I was so gobsmacked when I added a PowerLine to my SuperUniti, from pretty much disbelief to utterly convinced, I never noticed any burn in .
That cable and a couple of others moved on to my current system so I guess any burn in window is long past.

Soldered or tinned is not allowed for the reasons explained about solder melting before a fuse etc might blow.
Even tinned cables carry the same current and can melt regardless any tension on the connector would be lost as the solder melts.
When I started fitting Power Lines to my system I completely forgot to consider putting one on my Napsc. However, once I did try it I wouldn’t go back, so my 250 had to live without until I sourced another.
The PL on Napsc made lyrics easier to decipher and that was more important to me than making a bass line easier to follow,

The Powerline works well with most Naim products… I understand it’s more about the connectors rather than the cable. I find most effective on PSUs and amps and your elected source earth ground reference.
The appliance sockets on many Naim products is loosely mechanically attached to the case, and the Powerline mechanically clamps to the connectors in the plug making a very tight connection.
In my experience there is a shortish ‘burn in’ which I believe is more about the mechanical pressure connections seating themselves over a period of time… which is not dissimilar to DIN connectors optimising over a period of time.
I have found Powerlines on non Naim products usually hit and miss… I suspect because some products don’t loosely couple their mains connectors.
Thanks Simon, I am always astonished by the loosely attachment functionality
