i'm wanting to bypass the caps in my crossovers with the vishay 1837 as per Tony Gee's suggestion on Humble Homemade Hifi
however i also see on the market rubycons and orange drops 10nf caps. could they be a safe alternative to the vishay? any one of them actually a better choice? please let me know. cheers.

Here's what Douglas Self says in his book Small Signal Audio Design p.55:
"Clearly polyester gives significant distortion, despite its extensive use in audio circuitry of all kinds."
He says polystyrene and polypropylene have no measurable distortion (p.56).
I finally broke down and bought some of the 0.1uF (not 0.01) Vishay MKP1837 (from PartsConnexion $2 each) per Tony Gee's suggestion to use in parallel with the main caps in my crossover (3x 10uF Rifa PHE426 from Apex Jr $3 ea - Tony G rated them "7+"...), but I haven't tried them yet. I don't think I'll take the time to listen for a proper comparison either, as it would take too long to make the swap. I expect to feel better about it though, probably as good as one can feel for an extra $4....
