Crossover Capacitors for Accuton Tweeters - Solen -> ClarityCap -> Jupiter -> Duelund

@cal3713, I am happy to hear you found the right cap for your PREs.  Having had the pleasure of a long audition of the PREs, I can well imagine that the Accutons could be a bit on the aggressive side depending on other system components, the room, etc.  BTW, are you still driving them with Franks?

@cal3713 , thanks for the update on your journey through the amplifier jungle.  Pretty fascinating stuff.  I am a little surprised that the F4 clones ended up on the top of the heap.   I've had an itch to try one of the Pass or First Watt amps myself, and I think I would also enjoy the diy experience.  @grannyring may have created a monster by holding my hand through the rebuild of my Super Victory II crossovers.  Please keep us informed after you have a chance to evaluate the SITs vs the F4s.  

"enjoy the MUSIC NOT DISTORTIONS."  Friends, Raul has said a lot with that statement.  

Forgive me, but I've been down an epistemological rabbit hole for the last couple of years with respect to in home reproduction of music.    So I am going to challenge what might seem like an indisputable maxim.   Now mind you, I replaced my dearly beloved 300B Frankensteins with my equally beloved Atma-Sphere M-60's, precisely because the Franks, in my system and room, were driven to OBJECTIONABLE levels of distortion.  It would seem clear, would it not, that I would accept Raul's premise?  Sorry.  I have to ask, "What is wrong with enjoying distortions?"   If a 300B amp delivers an engaging listening experience with 3-4% 2nd harmonic distortion, so what?   What is wrong with that?  Does a 300B with all of its glorious midrange bloom deliver a typical live venue experience?  I would answer that question no, but clearly others would answer that with an emphatic yes!  I don't frequent the same venues as Charles, and those venues with which I have experience don't even deliver a consistent voice.  Charles isn't objectively wrong or right to prefer his Franks over other amps he has tried.  Cal3713 isn't objectively wrong or right to prefer the Duelunds over something else.   The have gotten what they sought from the choices they made.  That means they made good choices.

I'm not so sure that accurate reproduction of a live venue is even the desirable target.  I once heard Isaac Stern performing a work in a venue that was dead.  Somehow, he managed to emulate the death cry of a tortured cat with his violin.   I would not be interested in reproducing that performance in my listening room. 

We all listen critically to music for a reason, but I suspect we do not all listen to music for the same reason.  In fact, I as an individual listener don't always listen for the same reason.  Sometimes, I want Beethoven.  Sometimes I want Chopin or Schubert.  Sometimes, most of the time actually, I want Bach.  Why?  I won't take the time to provide the answer.  If you know the music, you understand my point. 

There is a place for first principle knowledge, and there is a place for experientially (or experimentally) gained knowledge, and there are different types of experiential knowledge.   Those who achieve their goals have usually done so by balancing the science and the esthetic elements. 

Sorry for the rant.  Too much intolerance of intellectual diversity has become the norm.  

@rauliruegas I may not be following your line of reasoning correctly.  If I am missing your point, I apologize.   Consider the music of Jimi Hendrix and Jimmy Page.   These two individuals, by almost unanimous consent, are two of the greatest guitarists of all time.  It is my understanding that they both deliberately introduced distortion into their guitar work.  It was a part of their creative expression.  Distortion was/is an integral part of their art, and without it, the music cannot convey the intended message.  Or consider Nelson Pass, who developed a 2nd harmonic distortion generator for those who wanted to introduce a bit of SET flavor into their solid state system.  My point is that not all distortion is subjectively objectionable.   My previous mention of the great violinist Isaac Stern delivering a live performance that emulated the death cry of a tortured cat, which I hope never to hear the like of again, provides an example where a perfectly undistorted absolute reference recording would not be subjectively desirable.  

Recently, someone mentioned that it is generally not good for a listening room to be ruler flat.  Rooms that don't have a bit of high frequency roll off can be perceived as too bright.  Consider another scenario.  Typically, one's ability to hear the highest frequencies is diminished as one ages.  For such an individual, might it not be advantageous for such a person to have a system or room that provides an offset for that hearing loss?

I'm not saying there is no value in measuring a room's frequency response and decay times.   Those measurements can most certainly be a guide as one attempts to optimize a room.  But the final arbiter must be one's ears.   I'm not saying there is no value in taking objective measurements of hardware.  Those measurements can be invaluable in assembling a system that works well together.  But the measurements cannot tell you how a particular piece will sound.  Again, the ear must be the final arbiter. 

Most of the folks around here are well informed listeners.  They frequent live venues and have a pretty good idea what a recording of acoustic music should sound like.  They also know when a system, a system component, and yes, a particular capacitor delivers that special level of engagement, which may well not measure as well as another choice that may objectively measure better.  

Enjoy the music indeed.  Don't worry about the distortions until your ears or your emotions tell you that you need to worry.

"our hobby is all about MUSIC."
Exactly!  
I suspect if we sat together in a room listening to a piece of music we would have similar reactions to what we heard.  I think that most of what remains between us is due to language differences, not differences in substance.  
Enjoy the music!
