Previously MOT: Cables For Less
Does anyone use 22 AWG even for full sized headphones? Isn't that overkill? Sure, and Axios cable is effectively 20 AWG (4 x 26 AWG per connection), but from my limited understanding of electronics, a 24AWG wire with 30 cores should be able to handle over an amp of current.
Also, I thought the rule of thumb is to divide the impedance of the headphone by 10, and them pick a cable that is lower than that number.
For mogami W2893, .13 Ohm/m, so assuming a 2 meter cable, the 26AWG wire should be good for any headphone > .26 Ohm.
Am I misunderstanding? Thanks.
Also, I'm gonna ask second question. Anyone have experience mixing copper and silver cable, say an 8 strand cable, 4 copper, 4 silver, one of each to each connection? Best or both worlds, or just silly?
I have not tried the mixing of copper and silver so that is the easy part to answer.
The .13 ohms is dc resistance and resistance goes down as the cross sectional area of wire goes up. Impedance is a combination of resistance, inductive reactance, and capacitive reactance and varies with frequency. I would have to read more about that rule of thumb to do a comparison but I would think 24 or 26 awg would be fine for the power levels supplied to most headphones.
