Mica foil capacitor (http://www.lautsprechershop.de/hifi/index_en.htm?/hifi/condens_en.htm) from the “lautsprechershop” website in Germany.

They contend that a small bypass capacitor added in parallel, or “impulse capacitor”, of about 0.010 µF will make it better for transient response because “every capacitor needs a specific time to charge which is proportional to its capacitance”.

So, my question is, if a capacitor of 0.010 µF (cost: €41,00/for the mica-cap foil) does ameliorate the sound transients, can a small capacitor (let’s say) of 0,1 µF (with a cost of €2,60/not a mica foil) in parallel with a bigger cap 20, 30 or 40 µF work also in the same way giving a better sound response and helping recharge the bigger cap?
Best Regards.
