Dear friends: Other than my first hand experiences with diferent caps for speaker crossover I was reading a lot of information about that includes diferent whole tests and capacitors evaluations.
The common way to write of the evaluations gentlemans is almost the same for all the boutique and top rated capacitors where the adjectives used tells us many glorious characteristics but in no one say the response is flat everything for them in this capacitors top range talks about colorations more than accuracy or flat response.
In the other side and at the other extreme when talk of the " poor " capacitors as Wima, Vishay, Clarity, Audience,Jantzen and the like they say:
" overall presentation is a bit flat.. """, "" you get a neutral, smooth and well balanced capacitor... """, """ Well balanced, overall coherent sounding capacitor... """ , "" Overall performance is very satisfactory and has something correct / complete about it.."", "" has high resolution in a natural way, it is without glare that you usually get with some of those "high-end" capacitors. """
And I ask my self: is it not that way as be or should be what we have to expect for any well designed capacitor?.
No one of those sentences came from " complex " design capacitors ( paper, oil beewax and the like. ) that for me alter the audio signal that pass through in a higher way against the straigth " poor " capacitors designs. Where that " alter " means fully colorations that the " poor " ones just do not have because it’s not part of the capacitor job.
Capacitor design/build is not a rocket science and as we already read it in the links I posted its job and contruction must be: straigth, the audio signal is not looking for the beewax or oil and the like.
As in one those links please think a little about: why those boutique caps that many of you " die for " are not used in medical tools/instruments or in the aircraft or military industry or in many other industry applications where what you need is : accuracy, precision, bullet proof, longevity and many other characteristics.
Or you think that to handle in the " rigth " way an audio signal we need those kind of boutique capacitors due to the audio signal " complexity "? make sense to you?
Yes, I know what you hear/listened and likes because I had experiences about and listen it all those nice colorations but what I did not listened was the MUSIC rigthness.
As I said before I own a lot of wima caps and after solve the speaker woofer crossover I will listen to wima, vishay and other " poor " caps in the tweeters and we will see then what happens down there.
For me the boutique caps are not for reproduce today MUSIC. Something similar as tube technology, both items can't really honor MUSIC today ( maybe in the past but not today where exist a lot better alternatives. ).
Regards and enjoy the MUSIC NOT DISTORTIONS,
R.
