BEST HARMLESS/SIGNATURELESS SPEAKERS CAPACITORS.

Dayton 1% tolerance poly caps measure very good and won't give you boutique flavoring on output. Tolerance is well withing spec and ESR is very low.

" Have I an explanation about? not for sure but now that the V-caps " disappeared " the hum gone with too.

Any explanation from some one of you? or an advise about?
"  Now my experience is with Klipsch but I figure what crossover components do with them they do with others too. All the old Mylar caps in crossover 20 years+ old i have measured after removal have at a bare minimum .15 ESR and often higher than .5 ESR. New ones I use measure maybe .004 at the top end. It makes for some downright sour sounding speakers at times until you switch them out. Best bang for the buck upgrade on older speakers is recapping your crossover and you don't need silly expensive caps to sound really good.

Dear @mahlman : If it's true that my ADS speakers are old it's true that this is not the first time I made or make a re-capping in the crossovers.

As a fact I already spended hundreds of dollars testing/changing the original caps with different boutique caps including: Duelun, Mundorf, Jantzen, V-caps, Sonicraft and the like and WIMA outperformed all the boutique caps.

Dear friends: There are other really important issues for the better with the Wima caps that latter on I will post.

I just measured the Powertron resistors that I bougth with spec of 1% tolerance for 12.00 british pounds each one. Each speaker needs 2 different values resistors.
Well, the Powertron are inside that 1% tolerance, in reality are at 0.5%. Powertron offers this model of resistors with a tigther tolerance as low as 0.01% for a very high price: around 80.00 british pounds for each one but I not only do not need that kind of tolerance but I'm not crazy to pay that price.
In the otherside and just because it was need it I bougth the Z-foil 2575 Vishay naked resistors with a 0.01% tolerance for my personal RIAA phonolinepreamp and for the Levinson's input resistors.

So, rigth now all the passive parts in the ADS crossovers are very well matched in between with lower tolerance. I remember that I paid a 10% fee to Alpha-Core inductors that alpha-core policy was that the ribbon silver ones only by customer orders, they had not on stock. In theory are matched at 1% or lower tolerance.

Dear friends : Even that this tread was and is converted in a " monologue " and not a dialogue as any other thread I feel that anyway I have to share my WIMA experiences.

First that female " body " that's not a rigth word for what I'm listening and what I want to say/express is: the dimensional space of that female " instrument " sound that through the Wima tooks an overall new " meaning " with very precise/defined tri-dimensional " body " and this happens not only with the female voice but with any instrument we are listening and the more impressive issue is that with complex music scores as Gladiator or the Tuttis in 1812 Overture or any of the Mahler symphonies or Berlioz  Fantastique Simphony or Beethoven 9th we can distinguish in precise way each instrument in its single/singular tridimensional space.
We listen the overall sound instruments mixed but we can " see " we are aware of each tridimensional specific space position in the stage as we do it only through near field live MUSIC event but just can't through a home system, at least not at the levls I'm doing it for the very first time in my audio life.


Other great listening characteristic is that if we pass from 95db SPLs to just  around 80db SPL's does not changes anything but the SPL . The MUSIC dynamics, power, natural color, transients, rythm, overall soundstage,  natural agresiveness and brigthness, decay time, detail and the like does not changes in anyway, so today I can really enjoy MUSIC at the early 80db SPL as never before in any room/system I experienced with.


The recorded MUSIC is looking for and is hungry/starving for friend's MUSIC room/systems and the best friend's MUSIC is the " audiophile " that facilitate or makes easy its reproduction trying to prevent/take off all the obstacles in the path/road of  that recorded MUSIC to denigrates it its integrity at minimum, preserve that MUSIC integrity picked up by the recording microphones.
The high-end/boutique caps goes against that main MUSIC target in a way higher levels that the humble Wima caps that IMHO is the only cap that puts me nearer than ever to that main and way elusive target. Till you have those Wima caps in your system you will follow listening to those high colorations/distortions and far away from the true live MUSIC.

Unfortunatelly we all are members of that " terrible/horrendous " AHEE where we learned all what we are in audio.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.
