You're not wrong! It's a curse this hobby of ours. It can bring so much joy but horrific doubt at the same time! Have I done this right, that right, are my speakers toed in correctly..... The list goes on and on. I sometimes miss my simple soundbar. Doing a load of measurements in the morning ready to install all the new cable etc etc. So there's a load of stress I don't need but, curiously, I'm really looking forward to it!

You're welcome! I think they great without the sleeving and, to be honest, I didn't even realise until you mentioned it! There's nothing worse than not being as ble to complete a job there and then. Eats away at you doesn't it (or is that just me)? Hehehe

Absolutely fantastic job mate! Love what you've done! Bonus that the missus noticed a difference though. Whenever Janine (my wife) mentions something you know you're on the right track as she really doesn't give a monkeys! You should be proud mate! Brilliant job.

See. This is why I shouldn't have said anything. I'm talking about 240/400V systems. The load a speaker draws pales in comparison to the loads I work with. Having said that, any electrical current WILL involve heat.

Hmmm. Maybe my side of things is slightly different to the DC/electronics side of things but I can assure you that the impedance of a cable does change with temperature. Once the cable is at full operating temperature, the impedance value is definitely different to the measured resistance when not energised. I see this on a daily basis when carrying out test & inspection. Not that it matters really as I honestly don't care!

Cool! Do you think you could post a few pics? I know it's a P.I.T.A but it would be nice to see your efforts!

I'm an electrician by trade and my understanding of resistance and impedance is that they are the same except that resistance is a value given in ohms on a cable that is not energised. Impedance is a value given in ohms on a cable that IS energised. On an electrical installation, when doing an Initial Verification (testing on a brand new installation), on each circuit, we measure the R1 (live cable) + R2 (earth cable) to confirm both polarity and to ensure the CPC (Earth) is not broken. This is a "dead test" with no circuits energised. After the installation is energised, we then carry out (amongst many other tests), a Zs (Earth Fault Loop Impedance) test on those same circuits. This is a test to ensure that the protective device will trip in the event of a single fault on that circuit. If the impedance (resistance) is too high, either the cable needs to be uprated (increase the Cross Sectional Area) to counteract the high impedance or the protective device needs to be changed to suit the impedance value. 99% of the time, the protective device is downrated/uprated to suit the impedance as pulling a new cable in is usually impractical. P.S. I'm not too great at maths either.

Interesting (if very lengthy) investigations which mirror my findings. I thought the very same, there can't be any difference between cables but I found there definitely is. I have been a Van Damme speaker cable user for a good while. When a set of Tellerium Q Black II came up for sale at a reasonable price, I decided to try it out. Now I listen to music set at 60 on my amp which correlates to 80dB so I swapped out the 4mm Van Damme for T-Q stuff. I instantly noticed a difference in the sound. There was more detail in the top end and I was hearing things I hadn't heard before in tracks I was very familiar with. I was shocked to be honest as what I was hearing went against my belief but its true, there definitely was a difference. Crazy huh.

Is it true that Phono leads have to have extra low impedance due to the low signal being carried by the cable?

Thanks for that pal.

Do you think you could post a few pics of how you terminate the cables just for educational purposes?

Hehehe. It's a godsend being bald sometimes! I'm doing OK and the scar is healing up well I just have to keep on top of the pain management meds. I've lost a lot of movement in my left arm though. I'm so lucky I'm right handed or this could've been a career ending injury! Im hoping the movement will slowly return over time and I'm sure it will if I exercise the arm each day. The height I fell (3 metres)....it could've been a LOT worse!
