BEST HARMLESS/SIGNATURELESS SPEAKERS CAPACITORS.

Said I: " terrible/horrendous " ? in reality is worst than that because it's a corrupted AHEE and we all belong to it.

Maybe some of you can have a different opinion of that AHEE but for me it's : corrupted ahee.

Dear @grannyring friends: Following your advise and as I posted I soldered the Wima caps in parallel instead using one cap with the capacitance need it value. So two caps in parallel to achieve that capacitance value. If I remember you told that the inductance goes lower.

In the other side that’s how Rel caps works and I used it, as a fact I still use the RTX series in the speaker back tweeter ( and add-on by my self. ).

Well, a few days ago I was thinking that I was using V-caps teflon Cu in the crossover in parallel as " by-pass " caps and when I take off from the Jantzen Alumen Z the quality performance improved then I made an internet research looking for technical information about the true advantages to use " by-pass " caps in speaker crossovers or caps in parallel and things are that does not exist a true technical/information that can corroborate all these.

So, I changed the caps in parallel in my speakers tweeter and band pass filters for a single cap at each crossover position and guess what:

the whole quality levels performance improved in significant way, almost everything improved and now I’m looking for the cap values I need in the other frequency ranges but it’s not an easy task to find out those cap needs.

Anyway that change is a learning lesson about and I think that through this thread I learned and I’m sure will learn some other true facts about caps through first hand experiences with patience and testing what no other audiophile dare or take a risk on this overall fascinating subject.
Certainkly I will never again use speker crossover caps in parallel or " by-pass " caps, problem as I said is to find out the cap stand alone cap.

Dear friends: The main subject in this thread is exactly its title.

In the past I already tested almost all the very expensive " snake oil " caps to know which is better, unfortunatelly all are more colored than a true cap.

Today I’m using my first true capacitor that are the WIMA ones but I can’t be sure if Wima achieves the thread title subject till I test other true caps contenders that can challenge Wima caps.
The only thing I know rigth now is that Wima outperforms with easy any boutique/high end capacitor.

So, I put an order for Kemet, Epcos/TDK and Vishay caps. I will do it step by step as with the Wima.
I ordered the caps for the tweeters and band pass crossover filters.

Btw, I don’t soldered yet the Powertron resistors instead the Duelund I use and I will change it till I finish the whole caps tests/evaluations.

When I tested the Powertron I will report on it. I’m sure it will be a true resistor and not a expensibe " snake oil " resistor as the ones I’m using. We will see if that can be confirmed.

In the mean time good luck for all of you.

Of course that I already ordered the input caps for the amplifiers that I will set up at the end of the overall evaluations and after the Powertron/Vishay resistor tests.

Dear friends : What a challenge for me and my room/system this overall true capacitors evaluation.

Due that all those true capacitors have not the normal snake oil capacitor colorations/distortions we have to have a well trained brain/ears and a real high resolution room/system to be aware of differences in between the different manufacturer true caps.
 Not an easy task to detect it those differences and if your system has not a real high resolution then you just can't say not only the differences but the quality levels of those " tiny "differences if you think exist those differences.

Things are that those true caps ( Wima, Vishay, TDK, Kemet, etc,. ) are caps that makes what it's supposed a cap must does and nothing more.

So and due that in the overall industry exist a fierce competence in between those true caps manufacturers the quality performance levels in between are to close, extremely close.

Rigth now I know that the evaluation will take me a lot more time that I was accustom too. 

At this momnet I'm very satisfied with my decision to pull the triger for all these kind of true caps.
I'm learning a lot and learning why this or that manufacturer took " some " cap design " characteristic and other did it in a diferent way.

Sure that I need more time and hard work with this overall true caps evaluation but what I found out at this begin with let me to order the caps for the mid range speakers crossover as for the woofer too.
