BEST HARMLESS/SIGNATURELESS SPEAKERS CAPACITORS.

Dear friends: There are other really important issues for the better with the Wima caps that latter on I will post.

I just measured the Powertron resistors that I bougth with spec of 1% tolerance for 12.00 british pounds each one. Each speaker needs 2 different values resistors.
Well, the Powertron are inside that 1% tolerance, in reality are at 0.5%. Powertron offers this model of resistors with a tigther tolerance as low as 0.01% for a very high price: around 80.00 british pounds for each one but I not only do not need that kind of tolerance but I'm not crazy to pay that price.
In the otherside and just because it was need it I bougth the Z-foil 2575 Vishay naked resistors with a 0.01% tolerance for my personal RIAA phonolinepreamp and for the Levinson's input resistors.

So, rigth now all the passive parts in the ADS crossovers are very well matched in between with lower tolerance. I remember that I paid a 10% fee to Alpha-Core inductors that alpha-core policy was that the ribbon silver ones only by customer orders, they had not on stock. In theory are matched at 1% or lower tolerance.

Dear friends : Even that this tread was and is converted in a " monologue " and not a dialogue as any other thread I feel that anyway I have to share my WIMA experiences.

First that female " body " that's not a rigth word for what I'm listening and what I want to say/express is: the dimensional space of that female " instrument " sound that through the Wima tooks an overall new " meaning " with very precise/defined tri-dimensional " body " and this happens not only with the female voice but with any instrument we are listening and the more impressive issue is that with complex music scores as Gladiator or the Tuttis in 1812 Overture or any of the Mahler symphonies or Berlioz  Fantastique Simphony or Beethoven 9th we can distinguish in precise way each instrument in its single/singular tridimensional space.
We listen the overall sound instruments mixed but we can " see " we are aware of each tridimensional specific space position in the stage as we do it only through near field live MUSIC event but just can't through a home system, at least not at the levls I'm doing it for the very first time in my audio life.


Other great listening characteristic is that if we pass from 95db SPLs to just  around 80db SPL's does not changes anything but the SPL . The MUSIC dynamics, power, natural color, transients, rythm, overall soundstage,  natural agresiveness and brigthness, decay time, detail and the like does not changes in anyway, so today I can really enjoy MUSIC at the early 80db SPL as never before in any room/system I experienced with.


The recorded MUSIC is looking for and is hungry/starving for friend's MUSIC room/systems and the best friend's MUSIC is the " audiophile " that facilitate or makes easy its reproduction trying to prevent/take off all the obstacles in the path/road of  that recorded MUSIC to denigrates it its integrity at minimum, preserve that MUSIC integrity picked up by the recording microphones.
The high-end/boutique caps goes against that main MUSIC target in a way higher levels that the humble Wima caps that IMHO is the only cap that puts me nearer than ever to that main and way elusive target. Till you have those Wima caps in your system you will follow listening to those high colorations/distortions and far away from the true live MUSIC.

Unfortunatelly we all are members of that " terrible/horrendous " AHEE where we learned all what we are in audio.

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.
