How to select a good Speaker Cable


Speaker cables do have a significant role in how our system sounds. Different cables sound different. 

So which one is the right one for you?

The Speaker Cable is an extension of the Amp. and not an addition to the speaker's load. It shall have a certain resistance (low) not to spoil the Amp's DF figure. As so, it can be calculated and there is a formula to do it.

The higher the Amp's DF, the lower the Speaker Cable's resistance shall be. As today SS power Amp's get DFs of 400 and above (Digital Amps go by thousands) the cable of 10 ft (3m) long, gets as thick as 0 AWG.

I can see your eyebrows elevates, when that thick cable is to be deal with. Most Speaker Cable makers skip it because of that. So most cables on the market (regardless of the look or price) are of 14-12 AWG. Way less that supposed to be.

Worst! no Speaker Cable maker, dealer or seller knows the answer, of what is the correct cable for your system. 

So most of us ended up, with a cables too thin for the task.

A conducted test, on this site, about a year ago as well as with some closer friends, shows a significant improvement with a calculated size cable over their previous cable. The results were all positive and preferred the calculated cable.

So, instead of asking: which of two brands, or two prices or two colors of Speaker Cable do I need, you should ask how thick of a Speaker Cable do I need.

I'll be happy to provide you the calculation, for who request it. All you need to provide is:

1). Length (Ft. or meter)

2). The Amp's DF figure.

I just use 0000 AWG welding cable. $40/ft at my local welding supply store.

I stand behind my calculations. 
Rather than do a comparison of the difference (R #10 awg - R #0 awg), 
Do R #10 awg / R #0 awg.
The ratio is 1:10
your DF 700 Ro is not correct: 8/700 = 0.0114 or 0.011 ohms, rounded.
It is significant.
Just read the sharing of those who tried it (if you have the time and the patient to read the thread of 2018:)

It's all there. People, that rather argue the numbers gave it a fair try.
The results are interesting: They claim that it makes a difference and a BIG one! 
Mr. fuzztone

Which model of tara labs did you purchase? How much did you paid for it?

The Omega (#4 awg) or the The Grand Master Evolution ( $000 awg) ?
Your favorite brand is thinking that the thicker the better. So this is a good start.

They do not link the need of such thickness with length or DF, but it well related to the price.
My recent check (about 4 years ago) suggested a price of $32,000.- for the Omega, at my local dealer.
I made my friend a pair of #4 awg (PASS LAB 250.8) for material cost:
Less than US $75.-
Up’s that’s a bit cheaper than the Omega...Yes, it came without a fancy box, nor fishnet sleeve (-:. 
I really don't think it makes a difference when he cleans the dust over the cables, once a while.

Now I’m into assemble a #0 awg, so he asked me to have it for a demo.
The material BOM is about to arrive till Aug. 5th. 
Even though the calculation shows that #4 awg is enough, I would be happy to see if a #0 awg improve the already good sound he has (B&W 802D).
