My Holy Grail of amplification found: Non-Polar electrolytic caps across power supply

[arnyk]

Cyril Bateman tested electrolytic capacitors extensively and shows in his article that bipolar electrolytics have the lowest distortion of the electrolytic type, also that the higher the voltage the electrolytic is rated for the lower the distortion. Cyril also shows film caps are generally lower distortion than electrolytics of any type. Also read Marsh/ Jung's artcles on capacitors for further information.

(go half way down the Jung page to the 2 part ' Picking Capacitor articles)

Ironically, despite some of them bearing titles such as "Capacitor Sound" none of these articles seem to actual include listening test results, either sighted or actual proper DBTs.
