2 questions please:

Any reason why I can't cut up a set of NVA LS3 cable and connect directly to my speakers unterminated?
Any reason why I can't cut up a set of NVA LS3 cable and reterminate?

Hopefully these questions aren't as stupid as they may appear :lol:

No no reason at all to both questions. Why all the chopping, have you just bought a new pair of wire cutters or something ?

Why? :scratch:

Simple reason: I'm interesting buying a set from Floyddroid which are far too long for my requirements.

Dare say they could be sent back to manufacturer for ..... na, just do it yourself ;). Unless they are fancy pants cables then it should be ok. Would need to ask someone who has before you do though

I'd like to thank you all on behalf of Steve as you've just got him a sale.

No reason at all why the cables can't be cut and reterminated. But you have to remember these cables use a Litz construction, i.e. they consist of several conductor strands (14 in the case of the LS3) that are individually insulated. To reterminate the cable, each strand needs to have its insulation trimmed back so the conductors can be connected together. How this is done depends on the actual termination: plug; spade, or bare conductor.

Hardly silly questions.
Direct soldered connections on Amps and Speakers is Far superior to even the priciest connectors made/sold.
Simple, direct and V effective.
However it can be a nuisance.. if an inveterate/constant fiddler.. as soldering /unsoldering can be a chore.

Your dead right, but I could never do it, I'm way too much of a fiddler. Gazzjam hardwired all of his mains, sounds like being in a straight jacket to me :brickwall:

NVA cables are not of Litz construction. Just because a cable has individually insulated strands does not mean it can be called Litz.
Below is an explanation of what a Litz construction is:

Litz wire is a type of cable used in electronics to carry alternating current (https://en.m.wikipedia.org/wiki/Alternating_current). The wire (https://en.m.wikipedia.org/wiki/Wire) is designed to reduce the skin effect (https://en.m.wikipedia.org/wiki/Skin_effect) and proximity effect (https://en.m.wikipedia.org/wiki/Proximity_effect_(electromagnetism)) losses in conductors used at frequencies up to about 1 MHz.[1] (https://en.m.wikipedia.org/wiki/Litz_wire#cite_note-Terman1943_p37-1) It consists of many thin wire strands, individually insulated and twisted or woven together, following one of several carefully prescribed patterns[2] (https://en.m.wikipedia.org/wiki/Litz_wire#cite_note-2) often involving several levels (groups of twisted wires are twisted together, etc.). This winding pattern equalizes the proportion of the overall length over which each strand is at the outside of the conductor.

The term litz wire originates from Litzendraht (coll. Litze), German (https://en.m.wikipedia.org/wiki/German_(language)) for braided/stranded wire[3] (https://en.m.wikipedia.org/wiki/Litz_wire#cite_note-3)or woven wire.

Litz construction causes high capacitance to be generated because of the woven construction and is therefore competely innapropriate in the context of NVA amps.

NVA cables are made of individual insulated cores in each leg but these are not woven or twisted in any way, neither are the individual made up legs twisted together, meaning that the construction is of low capacitance due to the randomised positioning of each strand relative to the other along the length of the cable.

It may sound nitpicky but does IMO need correcting as NVA specifically say in their literature, regarding their power amps, that low capacitance cable is an essential requirement.

Well that depends, over on the forum which I believe we're not allowed to mention here or you get sent to jail, I'm the biggest idiot in existence.

The term 'Litz' is used for any cable that uses individual insulated cores. If these cores are connected together at one end or the other, there won't be any 'high capacitance' as this inter-core capacitance will be shorted out.

Anyway we are talking about NVA cable, and all I was pointing out was the fact that the individual cores, or strands, are insulated separately; so re-terminating the cable requires more care than would be needed with the re-termination of a conventional multi-stranded cable.
