Neotech solid vs Dueland tinned vintage - spades? bananas? nothing?

@parrotbee Seems you are looking for a more advanced DIY cable.-

Take a look at this thread
https://forum.audiogon.com/discussions/duelund-conversion-to-diy-helix-geometry-cabling

I have tried several wires for my own DIY Helix cables and now prefer bare Neotech UP-OCC copper inside a Teflon tube. The results are stunning

Give the Helix cables a try - I think you will like them a lot

Start with speaker cables and migrate to Interconnects and then power cables

The Helix are well suited to amps requiring lower capacitance cable, such as Naim. They are not the lowest capacitance cables out there, but they are far from a level of capacitance that can do damage to your amp.

Here are the finished cable measurements...

Since you are mentioning spades/bananas, I assume you are talking about speaker cable.  If you use Neotech solid core, make sure you do a variety of awg size.  Like, use 16, 18, 20, 22 awg conductors for each RED / BLACK speaker connection.  If you want to bi-wire, I would use 16+20 for bass and 18+22 for mids/highs.  You can do multiples if you want to build a really thick cable (such as 16, 16, 18, 18, 20, 20, 22, 22).

Audioquest does a similar thing with their speaker cable.  The reason to use different awg is the larger awg such as 16 or 18 will not do high frequencies.  I think this solid-core solution will be better than Dueland tinned stranded copper. 

Make sure you get the teflon coated Neotech wire.  The PVC coated will absorb/restrict current, especially on the smaller 20/22 wires.

Since this is all solid core conductors, it's hard to use as a bare end.  It's better to terminate with a good connector such as Furutech FP-201 spade or Furutech FP-200B bananas.  I'd recommend the rhodium plated, but you can do gold-plated if you want a warmer sound.

No termination is the best termination.

I agree completely with jaymark.

I have tinned copper wire in two of my systems.  Cable pairs less than 100 bucks.  I love the sound of tinned copper.  None of my higher dollar speaker cables beat them and most don't touch it.

Depends why you're doing this. If its because you enjoy tinkering then try them all. If its for sound quality there are better out there for less money try a few and see. Synergistic has by far the widest selection range none of which are muddled like your Nordost so you might want to start there.
