AWG stands for American Wire Gauge, a standardised system of measuring the cross-sectional area of Cayin Tube Amp. This is utilized to figure out how much current a wire can handle. AWG causes much confusion for consumers, as the standard can be a little difficult to understand. Is 12 AWG much better than 14 AWG or vice versa? How come one cable looks thicker than another even though they have identical AWG? Is AWG a good indicator of quality? Does AWG matter, and if so, how? These are all good questions, and we’ll get to them shortly. Firstly, let’s briefly touch regarding how AWG is actually calculated.
How is AWG calculated? When a cable had been a solid circular wire, then AWG is rather straightforward to calculate. Take the area (pi x radius squared) to have the cross-sectional area, and appear the AWG chart (example below) to work out AWG. If a cable has multiple strands, a similar operation is done to work out your cross-sectional part of each strand, that is then simply just multiplied by the amount of strands to have the total AWG. However be mindful when comparing this figure as AWG is not linear. For each extra 3 AWG, it is half the cross-sectional area. So 9 AWG is about 50 % of 6 AWG, which can be half again of three AWG. Hence 3 AWG is quadruple the thickness of 9 AWG.
So how exactly does AWG affect electrical properties? You would’ve noticed by now that this smaller the AWG, the bigger the cable. Larger cables will have less DC resistance, which means less power loss. For applications to home theatre, this is certainly true approximately an extent. A rule of thumb is the fact for smaller speakers, a cable of approximately 17 AWG is sufficient, whereas for larger speakers anything approximately 12 AWG or even more will give you great outcomes.
Why some cables the exact same AWG look different in thickness? Two factors dominate here. Firstly, the AWG only takes under consideration the interior conductors. Therefore, a cable manufacturer could easily boost the thickness from the Audiophile Cables to make the cable appear thicker. This isn’t necessarily bad, as up to and including point increased jacket thickness reduces other unwanted properties. Just make sure that you don’t do a comparison by sight.
Another factor why two same AWG cables may look different in thickness is the way the internal strands are made. Some cables have thinner strands, while some have thicker strands. Depending on the size and placement of those strands, cables can be made to appear thinner or thicker compared to what they are.
Is AWG an excellent indicator of quality? In a nutshell, no. A big AWG (small cable) may easily be not big enough for the application (for example, you shouldn’t be using a 24 AWG cable to perform your front speakers). However, AWG is a way of measuring quantity, not quality. You ought to ensure that all of your speaker cables are of at the very least Line Magnetic.
Does AWG matter? How so? AWG certainly matters. You should ensure that the cable you might be using is enough to handle the power you’re going to put through them. Additionally, if you are performing a longer run, then even more thickness would be required. However, many people get trapped a lot of in AWG and forget the reality that after a sufficient thickness is reached, other elements enter into play. This then grows more a matter for “audiophile” features to settle, such as using high quality materials such gaqgbw silver conductors or improved design.
Wire gauge is unquestionably a great fundamental indicator of methods sufficient a cable is perfect for the application. However, it really is by no means a judgement on quality, or even a specification to consider exclusively. As a general principle, after about 11-12 AWG, thickness becomes much a smaller factor, whereas for the majority of hi-fi applications 18-19 AWG would be the minimum cables to utilize.
