Capacitor

Dear @charles1dad : "" So if a listener actually compared the Duelund CAST, VH ODAM and Wima capacitors and having heard them (In his components/audio system) found the Wima the least impressive he is wrong and misguided?

Wima is the only correct choice ? The other two capacitors are merely flawed, inferior, colored and distorted? It is totally irrelevant if the listener prefers the sound quality of the CAST or ODAM ? This preference is simply borne out of ignorance and lack of understanding? ...""

Answer to each one questions: NO, and NO ! but the colored and " flawed ".

Now, I experienced/first hands for years the " boutique " caps in my system and other systems and I " like " it what I was listened. Wima? no way that I thougth on them was a forbidden cap for me no matters what.

So: I was wrong? yes but the real issue is not about me or you or what I like or you like it or any one else.

The real subject is about caps and what they should do and what they must not do and the why’s it performs well or not. Tha’s why I share the first link in this thread that I was unaware of it when I started my caps thread looking for help trying to find out the: BEST NOISELESS SIGNATURELESS one, this is part of that thread title.

There I discovered WIMA/KEMET/VISHAY caps that was and is the answer for that cap thread title.

The discovery task was really hard for me because I was totally biased/married to boutique type capacitors. So I made efforts to be " unbiased " and started from " zero " with out my really big prejudices against Wima and the like.

I’m totally sure that with out that " unbiased " attitude I just can’t discovered what was in " front of me " for to many " follower " years audiophile attitude.

When I listened my first Wima through the crossover speakers what I listened I still have " present ": dullness sound with no " life ", my first thought was to forget about and return to the boutique ones but I decided to gave a few days not to the Wima caps but to my brain to " digest " that different sound I was experienced and thank's to that I started to learn what I was losting/missing with the Wima/Kemet/Vishay capacitors that existed in the boutique caps that I loved through many years and what I missed were its high COLORATIONS against the way lower colorations in the Wima cap.

@salectric , how many new topics available for any audio forum? Subjective vs. objective argument never ending and futile, as is the best whatever.
Tried the Russian PIO in a Latino clone Dyanco amp some years ago, warm, inoffensive, not top tier resolution, transparency.

Dear @jbhiller  : ""  Wima  are fine caps that do a decent job and meet spec. But they do not come close to things like VCap.  ""

A just two years ago my point of view was way worst against Wima that your nice words about.

Maybe the differences in what we think in the caps specific subject could be that I think you have several years more than me to be exposed to tube electronics and I left tubes ( I was with for around 10 years. ) years ago for full SS electronics when I " discovered " SS technology to sound reproduction.

My first hand experiences and even today experiences listening to other systems with tube electronics still tell me that tubes are more colored items than today SS units. I can say more colored and noisy.  

Could be that those colored and noisy tubes performance don't let to we can listen all the real Wima quality level performance and that those tube characteristics could hide the real quality performance of the boutique caps.

When we are accustomed to some kind of colorations ( coming from tube or SS devices. ) what we want it is more of the same with " higher quality "..

Due that Wima/Kemet/Vishay are low coloration caps just does not hide the weaks in electronic/speaker designs. Wima naked those colored units, so we don't like it what we are listening with the Wimas and prefer the boutique ones.

Btw, between others I used the Teflon V-caps you are using and can't does what the Wima /Kemet/Vishay does.

Raul, I get your points. Well made.  Do you work for Wima?  
Just kidding. 
I do believe I hear better signal through two of the Vcap lines and others. I agree to disagree.

You CAN use polar capacitors as long as you connect them back to back like positives together or negatives together.  This will HALF the value of the capacitance however. So if you intend to make a resultant of 10 uF of capacitance, you will use TWO 20 uF connected back to back. 
So this is one way of kludging it.  Another point to think is the LONGEVİTY of the capacitors. Polar ones will most likely be electrolytics and will NEVER last as long as film capacitors hence adding another reason to not use polars.
