A previous discussion included a statement about crossover components.

Good Morning 

I am in the almost finial act of upgrading my crossovers , while I don't consider my Thiel CS2.7 speakers as " high " end they are of high quality build except for the quality of the crossover parts .  The " made for Thiel " 1uf bypass capacitors by Clarity were the only high end component used .   

My thoughts on upgrading were to use the best quality that I could fit onto the board ,  I also decided to try to keep the sound signature by using upgraded film capacitors by the same manufacturer as well as increasing the voltage rating as much as the size allowed .

I have a few questions for the experienced here ,  How does a larger gauge wire on the inductors improve the sound ?  Has anybody replace an electrolytic capacitor with a film and heard the improvement ?  Have any of you moved the crossovers out of the cabinet or are considering moving them out  ?

here is another capacitor comparison , not nearly as many but still ...

he is using a tube preamp with only the capacitor in the signal path .
