BEST HARMLESS/SIGNATURELESS SPEAKERS CAPACITORS.

Dear @grannyring  and friends:  through this thread I " learned " a lot and for me it's not of personal preferences bias but for me is: what is rigth and what is wrong, no matters what I like .

In this thread my internal " mouse " made " click " when I made an overall research through the net about caps and read carefully a lot of information and along that all my past first hand experiences: good experiences and bad experiences too.

WIMA as Analog Devices or Texas Instruments are not corporations dedicated to the audio high end, as a fact all them just does not cares about we audiophuiles needs.

Those kind of item corporation are world INDUSTRIAL supliers for any kind of industries as: all digital industry, military industry, aero space or aeronautic enterprises, car manufacturers, medical industry and any one you can name it.

Why all the industry goes with them and other same kind of caliber suppliers? because the world industry are not looking for " snake oil " ( as us, including me. ) but they are looking for a matured and proved solid engeneering.

That's why I pull the triguer with the Powertron resistors when I remember of Vishay corporation that is an industrial supplier. I was willing to buy Path Audio resistors but this is a high end audio supplier not the Vishay levels.

Look, which kind of solder are we using?, normally audio high-end  like: Audio Note, WBT, Mundorf, Oyaide and the like.

Well I already used all those and several other coming from different " manufacturers " in the audio high-end market but from a few months now I'm using a specialist INDUSTRIAL solder supplier: AIM, nothing comes nearer to it and they have several kind of alloys, flux, etc, etc and even receive custom orders from the industry and manufacture in specific for that customer.

Well, we can't find out Wima cap´s or AIM solder in the high end catalog suppliers as HiFi Collectve or Parts conextion or M.Pertcy, you can name it.

Unfortunatelly we audiophiles are not accustomed to those great great INDUSTRIAL suppliers products that are way way a head of the normal high end products.

I know the high end industry is not rigth but wrong or not so good as we could think.

The fuses threads is a clear example of what I'm talking about and people die for that snake oil fuses. I was there but fortunatelly today I just don't use any input fuses in my system.

No, it's useless to test the ODAM cap´s or the Path Audio resistors. I go for that mature and proved solid INDUSTRIAL engeneering.

Please think about and better than that any one of you or all give you an opportunity to " feel " the reality/true of what you are listening even if you are way satisfied. 

Try to be opened for what you never experienced before: why not ? what can you lost?

Btw, the ADS bass range cap value spec is 100uf and my WIMA measured 101.2 and 101.6 on each channel and are caps with 20% tolerance specs.

Dear friends : I already soldered the caps and not yet listened nothing because I have no time to do it but I swirtch on the whole system to check nothing gone " wrong " with my job and something really good happened.

Things are that for whatever reasons the lice source system selection is as always dead silence but before the Wima bass range changes something change it about noise level through the analog switch selection:

my phononolinepreamp always was and is dead silence with any cartridge but from some time now through analog I had a hum noise in the rigth side subwoofer. I checked everything including the cables paths and even inside my phonolinepreamp unit and that hum noise just stays there an audible when SPL are rounding the 90db.

Well, guess what that hum noise just disappeared through the Wima bass range changes.
Have I an explanation about? not for sure but now that the V-caps " disappeared " the hum gone with too.

Any explanation from some one of you?  or an advise about?

Dear friends :  I already tested those fenomenal WIMA caps in the bass range crossovers.

Now, my speakers has 100% hard wired WIMA caps and at each filter caps crossover are matched in between with a very low tolerance of .04% of capacitance.
I don't know how important is that speakers caps match but my mind is more calm with.

In this thread a gentleman posted that is almost easy to be aware of caps changes in the mi and high frequency ranges and that he thougth that is difficult to be aware in the bass range.
Well my today first hand experiences is way different.

In the past and in several different threads I posted that as better quality performance levels in your speakers bass range  as better the whole system quality level performance and through this outstanding ( and I mean it. ) experiences with Wima I confirm again that statement and not only with my system but with several other systems.

Other than that hum that disapeared with no know reason the first way different listening sound that really impress me was the female voice " body " that aquired with those caps, I have not other word but body to explain what I heard and hear.

Second sound characteristic iwas and is with piano recordings where we literally can " see " the piano chords vibrations as if we been the piano player, just fenomenal ! !

Third was and is the extremely clear and precise definition of bass range notes/harmonics that you can follow/distingish as never before, just like in a near field live MUSIC event.
It's not only about bass range definition and resolution but a true overall foundation for the whole MUSIC system experiences.

Now, that kind of bass range very high quality levels makes that the mid and high frequency ranges achieved new quality levels: whcih quality levels?, you just name it and are there.

Yes, now I can appreciated many recorded information that was " hidden " through room/system distortions of every kind.

@grannyring  posted in this thread:

"""  while the Wima caps are masking it.   This would make sense as the Wima caps are not top class in resolution or refinement . """

Resolution?, well my take with a cap is not about resolution but sounds degradation. At the end the crossover caps  job is to let the signal pass through but the signal frequency filtered/blocked.

I can't be wrong with that statement but is my take. Now, WIMA caps makes exactly that: lest pass the signal with out DEGRADATION you can be aware and the high-end caps just can't do that simple job because those added colorations are not other thing that signal degradation, added distortions to the valuable and sensitive MUSIC signal.

When any one of you could make what I already did it you will fall in count all the why's of my statements 
It's not that WIMA works in my system because I?M totally sure it works in any " decent " room/system. There is no reason with this/that kind of proved solid true engeneering that Wima has and makes they are the industrial standard.

Btw, I already received the Powertron/Vishay crossover resistors that I will connect  maybe in 10-15 days now and I will report on it and how works against the Duelunds I'm using.

Sorr my mistake: the caps speakers are matched not at 0.04 but  at 0.4%.

The other " finger " mistake is that must read: I can be wrong and not what I writed: " I can't be wrong " because any one can makes mistaKES OR HAS MISUNDERSTOODS, including me or even experts. I'm not an expert.

Dayton 1% tolerance poly caps measure very good and won't give you boutique flavoring on output. Tolerance is well withing spec and ESR is very low.
