Apart from low capacitance, what makes it a good sounding cable Colin? What do the triple cores achieve? They are in each core 7 PTFE covered wires, it reduces capacitance , the same basic structure as TQ UB, but the outer plastic is narrower and is loaded with a compound which is safe but I will not discuss unless you want to buy the design. I am not going to make any more cable or amps etc. and I am at long last going to enjoy the music that dragged me down this hell road to madness and grief. I have made myself a Claymore and a M100 Super Pro and a nice DAC pre and I am going to chill. Garden centres here I come . |

Hey Paul, I will try I will tinker still and put bits and bobs here, and watch you all like a hawk. he he best to you all take care.

Hi Colin, I'm always interested in tinkering with cables. I'm not sure how to phrase this, but is it worth me playing with 2 X 3 multistrand cables separated out like the design, or is the PTFE separation between each strand such a key factor that it's worth retaining?
There's also the idea of twisting the 3 cores. As they aren't being twisted with the ones across the space, it won't massively increase capacitance, but will twisting do much of significance compared to just laying them side by side.
Maybe better if I explain my idea: I was planning to try 2 X 3 lengths of 6491 cable inside a wide fabric sleeve/jacket. I'd stitch the fabric sleeve before assembling to create a "pocket" on each side into which I'd insert the 3 wires.
I also planned to do the same with the stranded silver plate copper wire I currently use as a speaker cable. If the separation between individual strands is a BIG factor,,I will seek out another cable that meets this requirement.
Speaker cables have always made big differences for me. Playing around with your own wires and construction isn't behind anyone with opposable thumbs, so I'm almost qualified!

OK, I found silk covered silver plated copper to sound the best but it did absorb water and this was a problem. So the use of a cloth cotton type fabric may cause you to have problems. So I used PTFE I would loved to have used Kavlair (spelling wrong). Now twisted positive and negative together wrecks the capacitance but does improve common mode inductance, the latter is much better for amps. Some amps become unstable in capacitive load so beware.
On the TQ wire the diameter total of the conductors and the spacing made huge changes in the sound so that is why UB is wider than TQ Black.
The EWA cable I designed a new webbing in-between the conductors which reduced capacitance but increase the common mode choke.
So twist each conductor all insulated from each other then check diameter total, and thus now with the correct length calculate the inductor of two paralleled conductors. So it will be fine balance, try and get the resonant frequency of the cable to above 1MHz unloaded.
Now the maths is a pain but it is all out there on wiki and other sites, I cheated I wrote for Window XL a quick check prog then measured the result to come to a compromise at 4M lengths.
So TQ below 4M the inductance is a little low and above 4M the capacitance rises and the BW changes.
A bloody nightmare, one that few in TQ understood, well none in TQ understand still.
Balance and system loading is the key.
Have fun
Best Col

Thanks for the info, Colin. It's great to hear from a designer about their processes and conclusions. If I make myself a cable that's half as good as any of yours, it will be by happy accident. But then I gues I'm probably in the majority there, including your former associates  |

Look up James (Sovereign)cable he made with my help it sounds bloody great.
It such a shame he is no longer with us. RIP James

I followed that thread, Colin.
Although I never gotmto meet up with James we did exchange a few PMs and did a deal a bit ago. He seemed like a lovely bloke and was universally liked. I will take a look back as a refresher.

If you find the thread Westie, could you please link to it, would love to read it, tried searching couldn't find it.

I have tried to find it, OK I will work out for you a nice way to make great cable, but you will have to remind me as I get bogged down with other things to read and make, so prompt me please guys.

Wire is this :-   Use 3 off 7/0.3 for best results Use 5 off 7/0.3 for UB version Now this wire is very expensive, fit into a PVC plastic tube each set for +V and -V conductors, now space with a 55mm space of PVC strip and glue now have fun. Now EWA cable is very different and the compound to make tube/strip is about £10K for 1Km. and plus wire and tool a nightmare. |

Cheers Colin. Furukawa isnt half bad in price, 1.52£ per meter. Although, you have to buy a 100m. Not sure what UB means, So 5 leads for the positive and another 5 for the negative. I like the overkill  , 100m would make a spot on 5m pair. Already got some nice design ideas out of this one, much appreciated. I had been imagining getting some of this 0.6mm silverplated solid copper wire 8x8 per channel, pulling a cotton sheath on each strand and shrink wrapping the bundle, then sticking them to a soft rubber hose divider and flexible nylon sheath covering them. 5x5m will go around 60-100£ mostly on the sheaths. |

Sorry just logged back in. I think it was on Aidiochews? I'm doing something right now but will look

It might take me a few weeks to get round to it, but I'm definitely in. I will buy the 100 metres and some braided sheath which I will get run up on a sewing machine to make two outer pockets.
I'm just wondering about how many lengths of cable per side. Is 3 enough or should I go for 7 like James did? I will probably be using odd lengths at say 4.5 and 2.5 metres. My speakers are bi-ampable bi-wirable so I was wondering if it's worth using only the 3 runs per side so I can make up 2 sets of cable in case I do bi amp.
Option. 1: 2x3 wires per cable would make a single wire set using 42 metres, whilst two sets for bi wire or bi amp would use 84 metres,
Option 2. 2x7 wires per cable would use 98 metres
Would option 2 give a much better sound if I was single wiring? If so I may buy two reels.
