I have no personal experience with trying different caps, inductors and resistors in crossovers. A local builder of high end speakers that employ compression/horn drivers and wide range cone drivers does not like at all Mundorf and Duelund capacitors. This is a matter of taste and particular application, so it is not necessarily a comment on the quality of such parts. But, it does mean that "best" can only be determined by experimentation, with the recognition that any particular swap might not work out for the better.
That builder will be supplying me with a new crossover for my speakers, but, the parts are quite exotic and hard to come by (Western Electric paper in oil caps). I hope it works out for the better.
