I'm working out details for my first charge coupled crossover. A 14μF cap needs to be replaced by a pair of 28μF caps in series. 28μF isn't a standard value, but I can get close with a 24 and 33μF in series, or a 22 and 39μF.

How big of a deal will this asymmetry be? Would I be better off paralleling a bunch of smaller caps to make a pair of 28μF equivilants? (6.2μF x4 and a 3.3μF would do it)
