I don't doubt the science behind speakers cables at all. There are measurements and lots of things I don't understand.
All I can say is that between the generic and Audioquest type 4 there was no difference in sound at all. But when I then swapped to the Tellurium there was a significant improvement. Every other aspect of the test was kept the same, speakers and amps in the same place. Furniture in the same place etc.....
I know all speaker cables aren't made the same which is why there will be different sounds. But all I can say is that between the £16/m and the £50/m speaker cables I tried there was a huge difference in sound. Whether this is down to the way the cables are made or materials of the cable or not I don't care one bit. It's just a much better sound and I am happier for it.
Prices are meaningless in this context. Nordost sell inadequate speaker cable called Red Heaven or some such nonsense that will sound like bell wire because it's simply too thin and high resistance.
You need 4 or 6mm copper on a longish run. Any idea what Tellurium is made of? If you did, you could duplicate it at a fraction of the price.
There are more important factors than just cable thickness/loop resistance.
To give you an example, a 2 sq.mm cable (in this instance from Atlas) exhibits just under 17.0 mohm/m resistance.
The same cable in a 3 sq.mm diameter measures at 12 mohm/m.
Now if you think this is a big difference, the former equates to a power loss of 0.018db/m.
The differences for for both inductance and capacitance are fractionally different, the former very slightly higher, the latter very slightly lower. - Minute differences. Both cables easily sufficient for your average domestic lengths and power ... . It only becomes problematic if using very thin cabling which may impair loudspeaker control with a typical (small) power loss.
There are other contributing factors which can determine the (measured) and subjective outcome between differenct cable constructions; Leakage (poor insulation materials), capacitance and inductance, an 'issue' with flat, parallel-geometry cables such as the ones used by Tellurium.
Not all cables are created equally and whilst I agree that price (sometimes) has less effect on the outcome good materials (and there is more to it than 'just' the conductor) do cost more and are usually reflected in pricing, some silly examples notwithstanding.
For those of you that want to construct your own speaker cables from scratch, you find that unless you use exotic conductor material, half decent insulation such as PTFE often costs more than the copper within. Even from 'non-audiophile' suppliers. Same for the sleeving. In case of more elaborate constructions, these easily multiply.
This is why I don't think that say £20/m is that much for a decent speaker cable for a revealing system.
Bear in mind that a lot of money is charged for termination but cable sellers. This can often add a substantial amount. Easily done at home even for the inexperienced unless the cable is something like litz wire or other elaborate construction which requires time consuming stripping before termination is possible. Even so, with a little patience many could save a few hard earned quid.
There are no doubt examples which bear little reflection on the cost of the materials but some of you seem to think this starts at a few quid a meter ... .
