To choose an adequate wire gauge, determine the amp draw (amperage) that the wire circuit will carry. Then measure the distance that the wire will travel (length) including the length of the return to ground (the ground wire running to the chassis or back to a ground block or battery. ...
For best results the input leads should be made with a wire of 22 gauge or larger wire. 5.2 Output Load The output load can be either an electronic load or a resistive load configured to draw between 0 A and 3 A. The output leads should be made with a wire of 20 AWG or larger ...
In addition, design elements used by such makers—which often include things like heavy hand-wired turret or eyelet circuit boards, or at the very least heavy-gauge double-sided PCBs—tend to lead to other higher production costs by their very nature, given the way that they're put together...
There are a lot of amplifiers purporting to be high end that are made for older listeners who's upper frequency hearing is shot. Some old reviewers like them too, and due to the weight they carry, younger users are convinced that the screechy bright sound is normal for hi-fi. It isn't...
You know that AWG18 wires have a resistance of approximately 21 mOhm (0.021 ohm) per meter, according to wikipedia :https://en.wikipedia.org/wiki/American_wire_gauge#Tables_of_AWG_wire_sizes and between power supply and device there's gonna be two meters of wire, so the total resistance...
