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 nearly the same qualities of dissipation factor (DF) and dielectric absorption (DA) as polystyrene (these are the two capacitor “qualities” that most affect audio applications).

There may well be audible differences between different types of capacitors for a given power supply/amplifier setup, but it's far more likely to be due to differences in impedances and resonances which may be specific to that circuit rather than the magical properties oft claimed for some brands of capacitors.

This is not an ideal world, and so real capacitors do leak DC. The formula given in the spec sheets is of the form: Leakage current = Constant * Capacitance * Voltage, The constant is typically on the order of .01 or less, and varies with the line of capacitor. For audio purposes, we don’t care how much leakage occurs when the amp is turned off.

"Audio Grade" vs "General Purpose" Capacitors for POWER SUPPLY

Hi, I'm building an LM3886 amp and for the power supply section, I need 2 10,000uF caps @ 63V. Snap in configuration is preferred. For the main bulk capacitors on an amp's power supply, would it make any noticeable difference if I used cheaper $7 Nippon-Chemi-Con KMH capacitors vs using. $18 Nichicon KG "Audio grade" capacitors.

The point of power supply capacitors in an amplifier is to provide a backup "reserve" for transient peaks. At some point, in any amplifier, you can tax the power supply with a big bass transient -- running out of current and/or causing the rail voltages to sag.

It’s almost always helpful to follow the voltage rails to the signal path since many times some local decoupling capacitors might be placed in this area as well. Heater supply in an Audio Research D51 power amplifier. The bridge rectifier is comprised of D23-D26 Next, we must decide which capacitors to put in place of the originals.

C5 and C6 are film capacitors that reduce rail high frequency noise. R1, L1, R2 and L2 are power ON indicators and may be omitted if you prefer. Increasing the capacitance value of the filter/reservoir capacitors reduces the ripple in the power supply's DC rails. It would also improve the low frequency response of the power amplifier and in my opinion, will be a much cleaner, …
