Mundorf (non-oil) Silver / Gold EVO MCap Supreme coupling caps in your tube amp ???

Its what the last two manufacturers of my preamp and amps advised, and about 20 other members who installed the exact same caps in theirs heard and reported back about changes - giving it time and hearing changes over time, after 100s of hours. If you don't believe any of this, that's up to you. There is nothing to prove to you. Nothing more to say.  Best of Luck on your journey.  

Dear @decooney   : It’s not that I don’t believe those manufacturers and the other tube owners. The issue for all of you is something that I posted and you still just do not comprenhed or has a heavy misunderstood. 100 hours or 200 hours the subject just does not change:

" after 300 hours to began to listen those caps your tube electronics surely sounds different but not because the caps are " formed " ( this is false ) but because those tubes changed a little or to much its quality performance levels and the other thing is that your memory after 300 hundred hours almost fail/fall completely to trust on i  t. "

Even your mood levels after those hours is different as is the electric power " contamination ". Maybe the SPL after those hour in this late listening session be a little dfferent than in the first listening session when you just changed the caps.

Exist several reasons why all of yu think that after those hours " things " are better.  

I don´t know from where those tube electronics manufacturers found out that " formed " about caps. 

Is normal that in your electronics when you change those kind of caps the sound will change and change because the colorations/distortions between both caps are way different due that those kind of caps are to colored and not neutral passive devices. As I posted all of you are using those " caps " as a " tone control " where in reality exist no control but only different distortion levels.

I know and trust what that you are listening and report but not for the reason you named. This is the issue.

Got it?

Decooney,
I just saw your message.
Now I have 105 hours on my capacitors and I can say things are getting better. The sound is smoother and more natural. I think, as you said, after more than 200 hours I will be more than happy.
In my Dynaudio Confidence C2 I changed the crossover to Mundorf Supreme EVO Silver Gold Oil, and it also took quite a long time to settle in. At first I was worried and a bit afraid about the change.
I didn’t use Oil capacitors in my Allnic power amplifiers, but I think I made the right decision.
Thank you for your reply, and let’s keep enjoying these Mundorf Supreme EVO Silver Gold.
I will be patient!
Best regards

I like clarity a lot but have found in speakers their larger values ( >4uF) benefit greatly from small value (0.1uF) copper caps such as audyn TruCopper

Dear @decooney ​​@josemar  : I can read  that after 105 the sound is smoother and more natural, obviously that you like those added capacitor distortions a lot because a capacitor a true capacitor by definition can's have a self kind of sound: a capacitor must be not natural but neutral to the signal that pass through it.

Those Mundorf model are MKP type capacitor and even the  " high end " Mundorf are not Self-Healing, go figure ( at least in the Mundorf site does not mention that critical and important capacitor characteristic as a fact the Mundorf information in site is very poooor but you can read:

" MCap® SUPREME EVO are the perfect liaison of the two aforementioned Mundorf MKP special designs and have been specially developed and tuned to meet the increased demands and possibilities of the latest generation of loudspeaker drivers  ".. 

With all respect all is bording stupidity to show those caps and tube electronics owners extremely happy with. 

The Wima FKP 1 is not a MKP type capacitor but  1 step up from the MKP caps. Here you can read about that Wima FKP 1:

Way different to a y other capacitor in the world even better than the best MKP from Vishay that's the other whole industry standard alog Wima. josemar/decooney can you understand the differences with your caps?

That " industry " means: military, medical instrumentstations, aero space, automotive, audio and every industry you can imagine. Tha's why Vishay/Wima are considered by engeneers the Industry Standard.

You will never see any " high end " caps as the Mundorf, Duelund, Clarity, etc in the Industry.

Well to each of you your own.

Enough.
