I would run all the caps in parallel...that way even small values would benefit from all frequencies. You have to decide what voltage/current you want to burn them in at. If you put 10V RMS into an 8 ohm load you get 1.25 amps of current....times 10v you are getting 12.5 watts of power. I have not done enough experimenting to know what voltage and what current to run things in with. When I did interconnects I ran about 12VRMS into a 100 ohm resistor...this gives .12 amps and around 1.44 watts. Normally an interconnect would never see more than 2 volts RMS and into a 10K load minimun....this would be .0002 amps of current and .0004 watts....so you see, what I was doing is 6 times higher voltage than it would ever see and also 6250 times more current. It certainly worked. Could I have used higher voltage and current....sure....will it sound better...I don't know. Play and let us know.If you are using caps in high voltage places (coupling caps and bypasses in tube gear, for instance)....you might want to bias the caps with DC as you burn them in. You could have one big cap as your voltage blocker coming out of the amp...put a 125V or whatever supply after it and then hook up your caps to be burned in and then the load resistor....this way the AC will pass through all of this and your caps will also have the DC bias on it that it would see in circuit. Just a thought.
