DAS is a decent cable

Stay away from so-called. CCA cables!
CCA (English) = Copper Clad Aluminum -> copper-plated aluminum
Aluminium has HiFi applications nix - but also nothing at all - lost! (At most beautifully made device fronts :-)
The copper plating gaukelt a simple front only that it is said to be a high-quality cable. No manufacturer, of what holds for HiFi applications on itself, offers such cables to connect speakers. Aluminum conducts current and thereby also the music signals significantly worse than copper, and is also brittle. Isolated to the cord and twisted it, the fine veins are already beginning to break.

Absolute standard are called OFC cable, like this one.:
OFC (English) = Oxygen Free Copper -> Oxygen Free Copper
means nothing else than that it is (almost) is pure copper in order that was processed to give not (hardly) oxygen came to material and the copper just not (or very little) is oxidized. The grades are therefore at 99% and better.
There are usually in expensive cables even numbers such as PC-OCC (pure copper) or HP-OCC (high-pure) or even UP-OCC (ultra-pure), or the purity is indicated as, for example, "6N" (meaning: 6 nines, after the second place, the point, as a percentage ie: 6N = 99.9999%) -> So all a question of purity and thus of the purse. Whether it ultimately sounds better - the discussion there's been around for many decades with fans on both sides. OCC is the way a specific production process for copper wires. So a lot of money for cable you are out only where the equipment is also correspondingly expensive -> and expensive for me is 5 digits for CD, amplifier plus speakers.

This cable is an OFC copper cable, 2x 4 mm² in cross-section and is perfectly adequate for me, nätürlich with +/- identification (red line = positive). Directly from the cable manufacturer (you wonder sometimes if eg HAMA cables produces really myself ...) Made in Germany - what more could you want? With me is 2x 4mm² use up to a length of 5-6 meters per side.

Who really needs to save where I can doubt only recommend the following: copper cable and then just thinner cross section. Again, stay away from the CCA-crap, no matter how many yards you need and how large the cross-section compared to copper cables, etc. etc. Who has a 5.1 or 7.1 surround sound system and 50m cable for 100 Euros may not afford to cut corners wrong end. Who wants to spend more may use a silver-plated copper, pure silver cables are always hard to get, and then sow-expensive.

This cable is perfectly reasonable, you can do nothing wrong, is inexpensive and fits due to the cross-section well in Bananas (speaker cable connector) or cable lug plug, so can be used universally and also can be soldered still good with normal equipment, who needs it (from 6mm² there's often problems because the heat dissipation is too good :-).

I use the cable the way to large T + A Speaker for many, many Euros each - good enough for me.

Here be careful: Quantity = 1 means 1 meter cable, corresponding to 2 = 2 meters, etc.
