How to Pick Audio Capacitors – Charrette & Beget
https://www.maxpierson.me/2009/03/17/how-to-pick-audio-capacitors/
A typical ESR for a capacitor might be .1Ohm, whereas a low ESR model might be .01ohm.Low ESR seems to be a much touted feature for audio capacitors, especially Black Gates. Since resistance is not dependent on frequency, however, I don’t understand how ESR would have any effect on distortion in the audio signal, and I doubt you’re going to hear a difference …

Some capacitors are designed specifically for low-ESR, but manufacturers of aluminium electrolytic capacitors do not specify ESR consistently. The value at 25°C and 100kHz is commonly quoted, with a formula provided to calculate the value at the operating frequency.
Why Low ESR Matters in Capacitor Design
https://passive-components.eu/why-low-esr-matters-in-capacitor-design/
In low noise amplifiers, low ESR capacitors are used to increase efficiency and effective gain. Class 1 ceramic dielectrics have excellent stability and low dissipation up to very high frequencies. They are commonly used in applications that demand low loss capacitors.

Sometimes low ESR capacitors are called low impedence. If you are using ceramic capacitors, the ESR for ceramic caps is usually so small it can be neglected. If you are using electrolytic capacitors, it is important. The line is blurred between low ESR and normal caps - there is no definite point at which a capacitor is low ESR or not.
Do I need shunt capacitors when using low ESR ...

I am upgrading the filter caps on the linear power supply of an old tube pre-amp, and I was wondering how important it was to use small value shunt capacitors in parallel with the electrolytics if my replacements are already low esr (in the 100s of …

The most nearly perfect capacitor would exhibit near zero ESR. Low ESR is essential for use in switched mode power supplies, but does a low ESR electrolytic ensure low audio distortion ? Of the 100 mF capacitors I tested, the 10 volt Oscon measured the lowest 100 kHz ESR of all, 0.012 W and 100 Hz tand of 0.035.
