In many cases ― mostly high-end electrolytic capacitors ― the proprietary dielectric material inside an audio-grade capacitor is meticulously manufactured to create robust, high-capacitance capacitors. An audio-grade capacitor''s goal is to minimize the amount of distortion and feedback between the audio and power signal.

With the bypass capacitor, the gain of a given amplifier is maximum and equal to R C /r'' e. Without the bypass capacitor, the emitter is no longer at AC ground. ...
$begingroup$ If we overlook the capacitor plate degradation for a moment, it''s not like putting a 30 ohm resistor across the line, at least not in one sense. I would indeed pass ~7.7 A and the apparent power would be ~1.8 kW but most of that is reactive power and would be lost in the power company''s equipment.

I used inexpensive Mallory 150''s as coupling caps in my recently built RH84 SE amplifier. Truthfully? ... And now with modern crap music production and delivery we get craptacular results that even the best caps can''t fix. ... And capacitor manufacturing techniques are in many cases vastly superior than what we had in the 50''s …
When a coupling capacitor is connected in an amplifier circuit, one of its plates is connected to the DC voltage coming out of a voltage divider. This tells me that it has a voltage on it. So now when the electrons from the AC signal come, won''t the electrons present on the DC side plate repel them? How does this AC signal cause electrons on ...
Bypass capacitors. They are connected in parallel to integrated circuits to keep their supply voltage constant when spikes occur (they are the same decoupling capacitors as above). Pulse discharge. A charged capacitor can release a colossal amount of energy when discharged in a short time. A typical example is the photo flash.

How To Charge A Car Audio Capacitor (Step by Step Guide)
It aids the amplifier by supplying the necessary power during brief surges, allowing the amp to operate optimally. Thus, while a capacitor doesn''t improve sound quality outright, it facilitates the amplifier''s performance, indirectly supporting better sound production. Capacitors'' role in charge storage and reactance control is vital.

A lower Vbe bring to a lower gain. That''s the negative feedback. If you put that capacitor to ground you will reduce this effect because at the operating frequency the capacitor will have a low impedance and so in parallel with Re will lower the whole emitter impedance, reducing the feedback effect.
