Capacitor


Dear friends I am interested to upgrade my caps in the tube preamp from Audio theta tin foil 3uf200VDC to Miflex1uf 240VDC copper foil what are your thoughts will reducing the value to 1uf affect the bass and frequency response or should I go with a higher value than 3uf

Dear @charles1dad @grannyring and friends:

Could be that I look as a condensendent person and that I not only know but are superior in audio subjects to any one else.

Well, that kind of " look " is only that because I’m different and certainly always learning from any gentleman as you and even from audio rookies.

I remember all of you that as you I was entitled with the boutique capacitors and against Wima like ones. Even every single audio item I bougth in the last 30 years my first step with was change all the Wima caps for " better " caps that always sounded to me better in exactly the same way as all of you.

So please don’t have a misunderstood on me and what is behind my posts. In my capacitor thread is all explained and through that thread I DISCOVERED Wima/Kemet/Vishay JUNK capacitors. Yes was a total turn around in my audio life and happened in the best time with my room/system when is fine tunned better than ever.

Now, the capacitor subject is not an issue of " I like it " but is first than all understand what does and what does not a capacitor ( that’s why I share that link. ). It’s a engeneering subject and sooner or latter we need to understand it.

It’s not true that top electronics designers don’t choose " boutique " caps because $$$ or because the caps dimensions or because " are not open to learning ".
Far aaway from there, the competition at that high electronics levels makes that all those manufacturers look to give to the market THE BEST OF THE BEST and nothing less.

In my thread I linked electronics with a cost no object price: 80K+ for an amplifier or over 60K for a preamp ( CH is an example. ) where the circuit boards are full of Wima or Wima like caps everywhere. These designers has no problem design with expensive caps because the audiophiles are willing to buy the products coming from those top manufacturers.

do you know its very high prices? maybe no one here can afford it and guess what : WIMA and VISHAY Roderstein caps.

Here other example:

Problem with all of us audiophiles and MUSIC lovers is that in reality " we are not willing to learn " not even to read something that " moves the land " as earthwake.


As audiophiles some of us ( including me. ) are at the hunt of " boutique " items that can " improve " our systems and we go for the more expensive and we don’t use or name/post Wima because is " junk " and we can " lost " figure and credibility. Unfortunatelly we are just followers and I’m sorry to said it.

It’s totally " weird " ( for say the least . ) that it does not matters the electronic/speaker item each time we change caps for the " boutique " ones always sound the better and is a full improvement.

How can be that way and what could means? it could means that the items designs all are WRONG designed because with the cap changes we " improved "?

So what are doing all those designers when with those changes we are better that they. We have better know-how?. Certainly not.

What is happening about has no real sense and something is wrong down there.
It’s not as @grannyring posted: "" try Wima on your own folks """ but to make an effort to understand the subject facts not " I like it " because normally what we like it is wrong or could be wrong but just does not cares us but MUSIC is to valuable to stay " static " and degrading it each time with those caps, fuses, resistors and the like " boutique " parts.
Yes, I know that we love those " colorations/distortions " that does not came in the recording.

@jasbirnandra the caps you can use all over your electronics or speakers can be these ones that I use instead of Cu teflon Vcaps I was using:

or and alternative in speakers crossovers due that has a wider uf range than the Wima and are very good too:

Ovbiously both with radial short leads.

Let’s all just enjoy what we have found that works for our ears and music. No need to argue. I am happy for Raul.  He has found what works for him and that is great.  I tried Wima based on his experiences and did not like them. I did try them however in a crossover as I am always open to learning.  Enjoy Raul and my fellow DIYers.  Have fun!
Dear @grannyring :  ""    what we have found that works for our ears and music. No need to argue. I am happy for Raul.  He has found what works for him and that is great...""

Well, one thing is that works for your ears and other way different that works too for MUSIC as comes in the recording. As in my thread you never posted and post true evidence/facts/measures for your " wonderful " caps that even in its manufacturer sites exist nothing that works as real foundation for your words.

Do you think that the Lamm owners are unhappy with their electronics? certainly not because in the Agon ads under preamps are around 200 units and no single Lamm.

Btw, in this overall cap subject is unimportant what we like it but what should be or must be:

THAT OUR ROOM/SYSTEM  PERFORMS AS NEARER TO THE RECORDING AS WE CAN ACHIEVE.

Obviously that you have a way different target. That's my main target and you know what: when you are near to achieve it not only you will like what you are listening but you will fall in love with because for the first time in your room/system you are truly listening to MUSIC not a colored/degraded presentation.

Of course that even that some day we can achieve that target we will stay still away from a Live MUSIC reference.

""  I am happy for Raul. "" come on. Other gentleman acuse me to be condescendent, I'm not  and I want to let you now that sincerely I'm sad for you but more for MUSIC reproduction in your room/system with that: "   works for our ears ..". 

Seems to me that unfortunated the real characteristics of MUSIC listen it at near field position are almost unknow for you or have a misunderstood about.

Anyway, my point is to help the OP ( as always. ) not if you agree or not. He has the rigth to read/know a different approach in favor of MUSIC.An approach that unfortunate goes against all of your opinions, that's unanimous .

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.
