Duelund JAM paper in oil , Cu foil Capacitors as coupling caps on Tube Amp

Dear @radni : Look, if your amplifier is a true good design and if you are a true music lover and not a hardware lover and before you pull the triger in any of those heavy colored/distorion and expensive caps you name it test these ones:

don’t be afraid or worry with because its price is so low, forgeret. Wima as EPCOS or Vishay are the true standards in the whole industry including audio but the corrupted AHEE teach us to go with the colored ( $$$$$ ) ones and not with a true capacitor.

Do you know that those caps with wax, paper, oil and the like was the ones used when the Radio started 60+ years ago? and only we ignorant/low knowledge about are using the same kind. Why? I already said it: AHEE lessons over the years and unfortunatelly ( including me. ) we all belongs to.

A capacitor is a simple passive devise to design and has an easy job to do: let pass the non blocked signal with out adding distortions or colorations. Why the signal needs wax, oil or paper? ask those expensive capacitor manufacturers that tell you and tell us why. Do you know why? me neither and exist no scientific explanation about any where. ? ! ? ! ? !

You can try, nothing to lost about and maybe you can learn " something ".

Wima are standards.  They make everything sound the same. 

:)

Dear @erik_squires : "" They make everything sound the same .""

well if everything means same electronic designs then agree with you.

Wima makes the true job/task inherent to a capacitor and will shows you the real quality performance level of your electronic/speaker designs, that’s why is a standard in the world industry: milatry, aero space, automotive, medical instruments, etc, etc. not only Wima is considered an engeneering standard by the industry but Epcos or Kemet or Vishay too.

I know for sure, because I have first hand experiences, that your statement is untrue and false.

I own or owned Levinson, Classé, borrowed Krell and all use Wima caps and no one sounds the same. I owned too tubes electronics.

Do you think that the next electronics sounds the same? certainly not and are electronics at the very top audio price range and use Wima:

here you can see why Wima is a true industry standard and not because I said it but because those caps have to meets Standards fixed by industry or engineering world associations as IEC:

Vishay is the same:

Now, please post the facts/tests that can attest that the audio signal need wax/oil/paper in the caps or at least measurements of Duelund/Jupiter, Vcaps and the like that proves it.

NO, that audiophile sentence : " I like it " is not not a test but not a fact and has not validity.

You are a gentleman that I think know in deep all my post meaning and knowing that I can’t understand why posted that kind of statement other than laughgin of me. I really don't care if you are making a joke of me, can't disturb me in anyway.

I used teflon Cu V-caps in my input amp and when I tested Wima there believe it or not outperformed the very expensive V-cap teflon Cu.

Same experiences as in my speaker crossovers where I used Duelund, Mundorf, Jantzen Alumen, V-caps, Sonicraft, etc and Wima/Epcos and the like outperformed all those heavy colored and distortion generators name it " boutique caps ": all of them ! ! !

Please show the study where it is shown everything that can be heard is already measured.

You betray your own logic. You insist that differences must be measured by old measurements, but you also claim Wima has outperformed other caps. Based on what, exactly?  So you may use your hearing, but I may not? Double standard. :)




Thank you,
