So it would be the left channel per the standard that charges both caps. However, it's possible that the OP's wiring is crossed somewhere. It's hard to tell that without a test track or other known recording; the sound stage is simply mirrored and still makes sense. | |

Thus, no high-pass and no "loss". But that also means that their speakers can receive DC offsets that don't do squat except heat up the voice coils. "Power compression" is when a speaker heats up, which increases resistance, and therefore draws less from a voltage-source amplifier for the same setting. | |
| Aug 11, 2017 at 22:40 | comment | added | Jules | @MikeP - in my experience, audiophiles would be unlikely to have an amp that runs off a single supply rail, and therefore have a very small DC component, so probably wouldn't bother. I mean, adding that resistor in there turns the whole thing into a high-pass filter anyway, which means some of their signal is being lost! | |
| Aug 11, 2017 at 20:59 | comment | added | MikeP | Largish is a good technical term, simply meaning between > and >>. So, with an 8 ohm speaker, 80 - 800 ohm resistor. Given it is a discharge circuit, whatever is lying around would work ok. Audiophiles would calculate it... | |
| Aug 10, 2017 at 22:10 | comment | added | TimB | +1 for adding a largish resistor to ground across the outputs of the amp on the right of the cap. | |
