BEST HARMLESS/SIGNATURELESS SPEAKERS CAPACITORS.


Dear friends:I really need your helpwith first hand experiences with speaker crossover capacitors founded in next main experiences/tested premises: for a 3-way speaker design, high resolution audio systems, very low distortion audio systems, wide systems frequency range, " zero trade-offs ".

I know that the best capacitor is NO-capacitor, well I need your near to that full experiences with another desired premises from you: audio systems using SS electronics and mainly listening MUSIC through digital sources.

All your opinions/help are appreciated.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.

My experience is polar opposite of yours. Could not remove Wima caps fast enough from all manner of electronics. Strange thing this audio hobby. I find Wima average or middle of the road at best. Go figure. Their lead outs are steel, not even copper. Not good for sound. 

I am happy you love them! The price is certainly right and that is a good thing.  
They are used for cost reasons mostly. Gear is full of them and no way the high end builders could use a much more expensive part that is used so extensively. Circuit boards are full of them. The already high priced gear would cost thousands more in some cases.

Small physical size is another reason why they sell. They fit well on modern circuit boards. They are on spec and available in great quantities. They are good at what they do for sure.

Lastly, they just sound good, not great, but do little or no harm to the design. Doing harm is a different standard than bringing out the gear’s very best however. 

I just experience this part differently than you it seems. Again, I am glad you like them so much.  I am sure it is a subjective preference based on your particular assortment of gear, room and ears.  I suppose there is no right or wrong here. Just differing experiences and conclusions. 
I know you think that. You are entitled to your opinion and I trust you are having fun.  The Duelund tinned copper caps are just marvelous as many builders know. Many builders are also love the Vcaps I mentioned. Seems many of us have been duped 🤓. 
Chris is a great guy.  I have put those Odams into many pieces of gear for customers and they all really enjoy the results.  
Understood.  It comes down to personal preferences and sonic bias as mentioned early on.  
Magic is a good and proper word not just an audiophile word to be meet with distain. It rightly gets at the notion that some sensory experiences are hard to put into words and explain. In audio it expresses a sense of wonder and immersion into the music at deeper levels than previously enjoyed.

I honestly think your now obvious anti-audiophile bias is greatly influencing and predetermining many of your tests and outcomes. 
I have listened and tested caps for decades. Your comments are starting to irritate even someone as patient as me. It is fine you have a subjective opinion. It is only an opinion based on your ears, likes and music. Saying other caps are “junk”, “snake oil” and all the other demeaning comments you make is completely false and just not reality. Please stop it with your “Only I Know Best” attitude. Countless other designers, modifiers, builders and DIYers with astute hearing Combined with exhaustive testing have all come to a very different conclusion than you. We are not all wrong. Time for you to back off of the rhetoric that has turned into bashing companies that are passionate and quite experienced with making top grade parts.

Not sure what your motivation is, but you have crossed the line of professionally sharing ideas and experiences and now come across as a person with an axe to grid. You do not hold sole ownership of truth on this subject. You have a subjective opinion only.

I find the caps you like marginally acceptable at best. Steal lead outs have a sound and it is not good to many ears. You like it, but many don’t compared to the better built caps with better sounding materials and design. Wima is not junk. You are not a bad person for loving them, but just open your mind to the fact that others hear things very differently.
Sure.  Can’t read this thread anymore.  I’m out like on Shark Tank. Enjoy your ride! 
You may want to try the new Vcap Odam as they are more neutral than the PIOs you don’t seem to like. They are much more 3D dimensional than the Wima cap and not very big physically.

It sounds like the better caps are revealing some negative sound attributes unique to your system and ears while the Wima caps are masking it.   This would make sense as the Wima caps are not top class in resolution or refinement. That is why I say this can be very subjective based on your system’s sound including It’s relative sonic strengths and weaknesses. 
Glad you like them.  I would not paint with the broad brush you use saying all boutique caps are a joke.  I tried Wima and they are nothing special to me.  Certainly no Vcap Odam or Miflex copper foil! 
This is all subjective based on your ears, preferences and particular room and piece of gear the caps are installed in.  
Great when you find something that works for you. 
Over at the Humble Capacitor review site they liked it fine giving it a rating of 8 which is pretty average. Not poor, not great like many “boutiques”.  That jives with my experience with these in both crossovers and electronics.  They are pretty average.  The quote from the Humble site.....

WIMA MKP 10 100VDC - 10% tolerance

Technical specifications (according to manufacturer): "Pulse capacitor. The construction principle of the series WIMA MKP 10 consists of a non-metallized dielectric film and an carrier film metallized on both sides acting as electrode. Thanks to the metallization on both sides, the electrical conductivity is considerably improved and the contact surface between the electrodes and the schoopage layer is doubled. This results in better contact and allows for high current and pulse loading capability. The properties of metallized capacitors such as excellent self-healing and high volume capacitance remain unchanged."

Sound: With the WIMA MKP 10 you get a neutral, smooth and well balanced capacitor. For this price range the amount of transparency is quite reasonable and overall the MKP 10 is pleasant to listen to. Compared to the similar shaped and sized Mundorf RXF the presentation is more forward and a fraction less clear. But never the less it has good overall sound qualities. Don't forget to give it some time to burn-in. Fresh out of the box they sound restricted and dynamics are limited. After several weeks of use they should open-up.

Verdict: 8




You can just parallel the ODAMs for use.  Lower inductance that way and that can be a good thing.  I used two 4uf caps instead of an 8 uf for example. 
Good experiment and results for you.  That is great.  If you like it more, then that’s all that matters! Enjoy!
