Audio Grade Capacitors: Technology and Applications
https://passive-components.eu/audio-grade-capacitors-technology-and-applications/
Capacitors are essential components in audio circuits, and they come in a variety of voltage ratings, shapes, and form factors. The integrity of an audio signal is greatly dependent on the choice of capacitors, and it is therefore necessary to consider various important factors when selecting the right device.
Audiophile Grade Capacitors

Any amp using them in the signal path will benefit by from the substitution of premium polystyrene or polypropylene types. The best capacitor types for audio circuits are polystyrene and polypropylene. Polystyrene is the first choice, but are only available in values up to .001 uF. Above that value, polypropylene is the type of choice, with ...
How to Pick Audio Capacitors – Charrette & Beget
https://www.maxpierson.me/2009/03/17/how-to-pick-audio-capacitors/
What impedance really represents for an audio application is how much distortion a capacitor injects into a frequency passing through it, by pushing back against a time-varying current. This makes low impedance one of the more important characteristics of a capacitor in the signal path, less so for a filter capacitor.

The use of capacitors in an audio signal chain is often fraught with mysticism and little quantitative analysis to justify capacitor selection. With many capacitors costing more than the integrated circuits they serve, it is a chal-lenge to determine a …

Depending on the construction, sound may be audible emanating from the capacitor, heavily distorted, but audible nonetheless. This can only come from vibration generated in the capacitor by the audio signal. Conversely a capacitor may convert vibration into electrical energy, particularly if the cap is biased by an AC voltage like an audio signal.
How to avoid a electrolytic capacitor on a (audio) signal ...

The capacitor above is a polarized type. The signal is not biased before. As far as I know, this is a bad use. I also verified my concerns with a simulation. If the signal really containts a negative DC (which this cap tries to avoid) the cap would/should fail or blow. So I want to replace it with a polarized type.

Every tube preamplifier has coupling capacitors (the caps actually in the signal path to block DC), and these caps must be at least "excellent" in quality to optimize that preamp's inherent sonic potential. Improving these capacitors is the most elementary and important modification that can be made. It is also, obviously, the most easily heard and appreciated.

Thank you for your inquiry about capacitors in the audio path around our SigmaDSP parts. In general, there are 3 types of capacitors that will be available in the values that are appropriate as AC coupling in most signal paths: electrolytic, tantalum and ceramic. Each has strengths and weaknesses.
