Capacitor Sound Explained: ESR, DF, Phase & Why Audio Capacitors Sound Different

Описание: In this video I show how to MEASURE audio capacitors and explain what actually determines their sound.

Instead of relying on brand names or forum myths, I measure real electrical parameters:
• ESR (Equivalent Series Resistance)
• DF (Dissipation Factor)
• Q factor
• Phase / loss angle

I demonstrate the process step by step using a lineup of 100 µF capacitors, including:
• Old Elna
• Panasonic FC
• Panasonic FM
• Nichicon
• Würth

I then explain how the frequency-dependent behavior of these parameters correlates with what we hear:
• clarity vs veil
• soundstage focus vs fog
• bass control vs softness
• transient speed and micro-dynamics

I also show how AI analysis (ChatGPT) can be used to interpret measurement data more effectively, and why a paid “Go” subscription can give better technical results — likely due to more advanced reasoning and physics-based modeling when correlating parameters like ESR, DF, Q, and phase across frequency.

This video is based on my long-form research and discussion on diyaudio:

The goal is not to crown a “best capacitor”, but to explain WHY capacitors sound different and how you can predict their behavior before installing them.

If you recap or design audio equipment and want repeatable, measurable results — this video is for you.
