BEST HARMLESS/SIGNATURELESS SPEAKERS CAPACITORS.

Dear @andy2  : As good analog/LP are the digital alternative already improved a lot in the last years and IMHO today is superior to the LP alternative.

Yesterday nigth I was listening the LP versions ( 33 and 45rpm. ) of Modern Cool by P. Barber that by coincidence I own too through a Blueray sample and the digital version ( 24/192 ) outperforms both LP versions.

If the recorded and mastering process are good/decent ones and everything else the same then 4xDSD OR 32/384 dac BEATS lpS but even a CDP can do it. Of course LP vs digital always is way controversial.

I used vcap TFTF in a tube Preamp as signal cap, it was nice  but did not sound natural to me. It is a neutral cap but came across as sterile after spending time with it, sounded great at beginning after break in but that wore off.  I use the Duelund silver as bypass in Preamp. Sonicap platinum bypass in a set of speakers. 

Dear @paulcreed  : Thank's to sharwe that information. Unfortunatelly for me is not usable because I need it for a way different audio item.

Thank's to every one posts. I already decided what to do for the speakers caps up-grades.

Dear friends : """ bypass > 5uF with a 0.1 copper film..."""

that was an advise posted by erik_squires and for years I was a follower of other " expert " followers of by-pass caps in speaker crossovers to use small value top caps as by-pass ones. I used teflon ones, silver or cooper caps. Latest the teflon Cu that I use with my Alumen Z in the Tweeters/bandpass/midrange caps.

Well, I already posted that my room/system has a very good high resolution and very low distortion levels and today I unsoldered all the by-pass caps in the AlumenZ and not what a surprise but what a great discovery that after running 3 times in a row my self developed whole evaluation system process what I’m listening rigth now is something totally new for the better of what I was listened just yesterday ! !. and I say BETTER not just different.

No by-pass caps makes a paramount differences in quality overall room/system performance. I have no words to describe the levels of quality differences.

For me and in my system listening LP and digital probably my big mistake over my audio life other that listened to tubes is with out doubt the use of by-pass caps in my speakers crossover. Never again.

Audience was absolutely rigth on that regards.

Dear friends: I forgot something where I was too a follower of " experts ".

Now  as a fact been a follower is something that one way or the other all of us did or do it in some important audio subjects and been a follower is a really good way to LEARN when we finally LEARNED because it's the way to learn with first hand experiences.
Other way to learn is that sometimes we can try to think " out of the box " on some audio issues and take actions about.
 This way is how I learned that pure silver cable is the best power cord you can achieve for any audio electronic items and in the same way I learned that the best fuse is not any fuse at all and it's that way how I use my system audio items.

Anyway, when I started to change the passive parts in my speakers crossover I read several times that a blend of caps could give me what I'm looking for and I did it for many years with some " good " results but latter on I learned that those " blended caps " diferent signatures was for me a wrong way to go: a mistake and started to stay using same cap manufacturer signature and the results are way better that the recomended " blended caps ".

I do it through the tweeter/bandpáss/midrange crossover caps and not with the woofers because normally I can't get same manufacturer quality level caps of 100uf value.

I learned that if I need to blend " something " in the audio system then something is wrong in the system chain and I need to identify in which system's link or links and make the changes to avoid the necessity of that " blend " recomendation.

Yes, that's me but audiophiles are singular human beens with different targets and approach.
