From http://sound.westhost.com/lr-passive.htm#s4.0 :
‘’There are some capacitors that should be avoided though, most notably bipolar (non-polarised) electrolytics. When they are new, they work very well, but if they handle appreciable current they will lose capacitance (and gain distortion) over time.’’ …but you may have no other choice for high values...
