BEST HARMLESS/SIGNATURELESS SPEAKERS CAPACITORS.

Paul, from where comes that dull kind of sound?, you can be sure it comes from the room/system set up, somewhere in one or more system chain links are not accurated because normally the majority of recordings are not dull ones.

In systemas that I listened with that kind of dull sound performance normally ( not always. ) the main trouble belongs to the overall bass range management and it’s not so easy to fix it but at the end it’s fixed. Both frequency extremes are critical but bass range is more dificult to fix it.

I can’t know where are the problems in your room/system because I’m not there but certainly exist a room/system trouble somewhere.

Wima only let pass with out degrade the signal generated through the system. This kind of caps are signatureless and harmless as no other caps.

Wima or similar caps can’t improve what is wrong, only can tell us that something is wrong. That’s what any well designed item will shows.

The Wima and similar caps design are really simple with out frills down there.

With all respect to all of you makes no sense to blind-trust in Jupiter or Duelund or V-cap instead where belongs the true proved capacitor engineering. Any one can build a colored cap but not any one can build an accurated one.

We can say: " I trust in my ears " ( me too. It’s what all of us do and what that AHEE teached and we all belongs to that AHEE. ) and after my first hand experiences about maybe it’s time for many of you to re-start/set the MUSIC reference ( near field position. ) main characteristics as the home system reproduction ones.

I have a lot of forward work in my speakers crossover caps. Things are that Wima and the like manufacturers have " hundreds " of model caps for very specific use not only 2-3 like the boutique ones where all those caps makes the same but some with silver or Cu or something like that.

I’m in the begin to learn that I can use and need to test several models to evaluate it and to know if can works in crossover or as coupling caps.

I’m already in this road and I feel the necessity to learn about. In the other side down there exist real fun.

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.

I wouldn't take it too serious everything is colored. Playing drums, the guy in the booth loves a certain sound, he wants a heavy wallet thrown on snare. That trick has been used a lot, that's what we are listing to a wallet on a drum head with our fancy stereo's and boutique caps. Playing with caps can make you forget about listening to music. Now we are listening to caps. That's why I like my main system I haven't touched or changed anything in 6 years, I know I can make it sound better but I don't. It's has First gen Joseph Audio Persepectives, I don't even know what caps are in there and won't look in there either, they play the same enjoyable reliable music year after year. Let it be. There is something to that. It can be more important than improving the sound. I'm still amazed how the boutique caps can change a system in a very positive way. For others less expensive caps sound better. I owned a Don Allen Preamp he used non boutique caps for the sound all for $800.  I have always regretted selling that amp it smoked my BAT vk5i SE with 8 amprex white label. It could play with $5000 and up amps loaded with cheap caps, so who knows what's best.

Dear @paulcreed  :  About dull sound there are several " things " to say about but please let me tell you experiences on that specific issue:

in the past ( as I posted here. ) every time I saw a Wima cap in electronics I take off and changed for a " better " cap.

Why I did it that way? well because that dull sound you talk about and when the " better " cap was soldered then that dull sound almost disappears.

Wima puts me in " automatic pilot " for a cap changes.  Sooner or latter we all learn and several years after those kind of " actions " and after overall system changes: electronics, cables, speakers, room conditionined and the like rigth now I'm took in count that several of those way better electronics ( that the ones in the past I used to. ) came with Wima caps not only at the power supply but in the signal path way of those electronics.

The main subject in all those is why these better electronics sounds/performs with so high quality using Wima caps when the before electronics sounds so dull?

easy answer: way better DESIGN. The dull electronics sounded that way because a poor electronic design or bad quality control or bad excecution to those designs. Were not Wima the guilty for that dull sound.

Two examples of those very good electronics designs are Mark Levinson and Krell.

The first Levinson item with the word REFERENCE in its model was the monoblocks amplifier: Reference 20 model that had rave reviews over several years and was an expensive unit.

I don't remember any single comment coming from reviewers or audiophiles telling the Reference 20 sound was: dull, never even today.
After that R20 Levinson puts in the market the stereo amp 23.5 model ( Class AB instead Class A like the 20 design. ) using all Wima caps and guess what: the 23.5 beated the R20 quality level performance and this fact obligated to Levinson to re-design the 20 and they gone out with the 20.5 that outperformed the 23.5 and always with those WIma caps.

After the 20.5's came the 20.6's that I own with some self tweaks ( certainly not on the caps. )/modifications. Still all the caps are Wima.

Thwen came the Levinson Reference 33 ( maybe some of you could remember this big size amps. ) and again with rave reviews coming from every where. 
Then appeared the Levinso first Reference preamp and as usually full of Wima caps and rave reviews too.

Along Levinson Krell was the one to beats and guess what: Krell uses Wima too and Levinson was a very hard competition for the Krell's.

No one told me all those was and are first hand experiences but all the owners and reviewers attest and attested why I liked and like it today. It's not about subjectivity because Levinson/Kreall measurements were second to none.

As I posted Wima can't do nothing for bad or wrong electronic/speaker designs where a boutique/junk caps can do it can " improve it " because are only adding more colorations/distortions.

Behind Wima no single item can hidden all its true quality performance levels.

The main issue it's not me or my system or what I like but the audio item designs.
 I came in this thread with out any single agenda and as a fact waiting for advises on boutique caps not on Wima or Vishay or Epcos and the like because I already " knew " that between other things those cheap caps just can't do it against all that very high engineering and design/tests ( that I never never seen in the manufacturer sites of these caps. ) dedication of the boutique $$$ " wonderful " caps.

Levinson and Krell are not the only today great electronic manufacturers that use the " cheap " caps almost every one use it.

Yes, Wima/ Vishay, Epcos or Kemet is my audio discovery and yes I understand exactly your meaning in your latest posts.

Regards and enjoy the MUSIC NOT DISTORTIONS,

Paul: Before those elctronics first hand experiences I had a similar one with Classé Audio DR-7 phonolinepreamp, NIL 3 ( pre-preamp/headamp ) and the DR-3VHC amplifier.
Was from Classé where I take off " dozens " of diferent Wima caps models and values.

A little late but fortunatelly I learned and I'm still doing day by day.
