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


I've got Coincident Pure Reference Extremes with an Accuton ceramic tweeter and have moved through four different capacitors to provide my high pass filtering.  The speakers only have one 4.7uF capacitor in the crossover (no resistors or other components), so it was pretty easy to hear the sound of each cap. 

Started with stock Solen's, then tried Clarity Cap CMR, then Jupiter Copper Foil & Wax, and finally Duelund Tinned Copper CAST.  Just installed the Duelunds on Monday and despite not being broken in, they sound absolutely amazing.  Smooth, sweet, and detailed without any grain or harshness.  Just really spectacular, they let me hear more details while also preventing the tweeters from being aggressive, which has been a problem I've had to work hard on ever since owning the speakers.  

To comment lightly about the other caps I heard, I actually thought the stock Solens were pretty good.  They had a nice sense of color... when I changed out to the clarity cap, things got a little clearer, but felt too neutral.  I read that they are "ruler flat" and found that a good description.  I liked the cleanness, but missed some of the tone & color from the Solens... felt like I got a good combination of those two traits when upgrading to the Jupiter Copper Foils.  After about 6 months of the Jupiters I finally bought the Duelunds as a self-birthday present, and they completely lived up to my (very high) expectations.  Just beautiful, organic music.  Can't wait to see where they go over the next 200 hours.  Only have 10 to 20 on them so far.  

If you've got an accuton tweeter and can handle the stupid cost (and size), I concur with everyone else's recommendations (thanks humblehifi, jeff's place, @charles1dad, & @grannyring), they will make your speakers sound better.

Dear @brownsfan  : I agree with almost all your post that's not " against " mine. What happened ( I think. ) is that due that english language is not my native language many times I can't explain things as need it.

Yes, not all distortions are really bad ones and exist every where including in live events.

I was aware about J.Hendrix but not Page. Yes I was aware too on N.Pass designs  whom and due that several high end customers were/are accustomed to tube electronics he choosed for something that can give a quasi-tube signature, that's was too why when in Threshold always used bipolar transistors in Pass he choosed FET/Mosfets.

Yes, it's true that through age always exist a degradation on the sound perceived sensitivity but we have to remember that we hear/listen trhough whole body not only the ears and that the brain knows and develops those harmonics that for whatever reason were not " listened ".

Yes, final arbither must be our " body ".

Don't worry about distortions ?, well I try to to take actions in my room/systems to put at minimum. I know that today I'm enjoying my listening sessions better that 5 or 10 years ago and I'm sure that you are enjoying the same as many other gentlemans.

All of us are growing up " day by day " as our room/system too. Our hobby is all about MUSIC.

Btw, I agree with @racamuti  statement on those distortions:

"""  Yes but, I don't want to add additional distortions to Jim or Jimmy's guitar just the ones they add. """

because we have to add to the distortion developed through the recording proccess and our system play process.

Dear @brownsfan  : """  What is wrong with enjoying distortions? """

in reality are not the distortion it self but the kind of those distortions and its higher or lower levels.

Distortions levels is what defines/makes differences in the quality level performance of any room/audio system.

All room/audio systems have inherent distortion levels, so always exist trade-offs and in each one of us systems we already choosed our self " best " trade-offs that put us nearer to our targets. Nothing is perfect.

"""  those venues with which I have experience don't even deliver a consistent voice  ""

agree. Everything in a venue could change each one of us perceptions of what we are listening, even attended in the same seat position. Things are that the  people that attend to the venue  the same day as us is not not only exactly the same number/popullation but their seated distribution is not always the same and certainly not always people go with the same kind/fabric of clothes and all those has influence in what we listening there. But even musician/players are not seated exactly the same each session after sessions and many times they don't have the same day by day " mood "
. Even room temperature could be not the same and temperature has its own influence in the instruments voice.
Normally the venues has an overall "signature "  that depending on those and other surrounded characteristics shows some kind of little " deviations " from the overall venue signature.

How can we enjoy MUSIC and not DISTORTIONS?  well we can't avoid several kind of room/system distortions and the best we can approach is to put at minimum those distortions and to achieve that we have to be aware/identify those distortions and this is extremely difficult and as difficult too is to be sure from where is developed that distortion.

Nothing is easy in audio when we are looking for " heaven " and this is what makes audio so interesting other that ENJOY THE MUSIC.

Dear @charles1dad  : I'm not saying I'm just rigth because if our reference is live MUSIC then no one can be rigth in any room/system combination no matters what.

I know I'm away from that target and I know too that every single link in the roo/system chain has its own distortions and colorations.
Diastortions/colorations that goes according each one priorities.

Each one of us fine tune our room/system according to those priorities that at the end is what we like it but several of our room/systems has its own limitations, limitations that preclude to really stay " there ".
Always exist beterr electronics or cables or speakers or whatever and no one of us already listening all the options out there so the best we can do is try to do our best effort to stay nearer to our targets.

Duelund's through my speaker tweeters just does not performs as I expected and where the Alumen and Mundorf makes a better job.

The Jantzen Alumen is extremely humble cap against the Duelund/Jupiter/Mundorf and many others and it's not Cu. Talking with Jantzen people told me that in this second part of 2019 they will have the Cu version and certainly I'm waiting for after the good results I achieved with this non Cu Alumen version.

Sweet or smooth characteristics are not in my MUSIC vocabulary, maybe at low SPLs but not at 87db-92db SPL at seat position and certainly in a live event seated at near field listening ( 92db-105dbs+! ).

In the other side same audiophile words has not the same meaning for each one of us and maybe could be an explanation of some of my comments.

Btw, I don't try to say that I'm rigth and he or " you " are wrong. Just different ways to " see the life ".

I'm not try to be condecendent with any one and agree with @cal3713  in his statement:

"""  Definitely it's a journey trying to get them to where I think they can go.  ""

Dear @grannyring  unfortunatelly for all of us our room/systems are different and certainly with different room/system whole signature. As @cal3713  and you and other gentlemans I'm where I like to stay where I enjoy the better my listening sessions and this is the must important fact for each one of us.
At the end my opinion is only that: just another opinion with no single attitude to fend any one or diminish anything at all.

Regards and enjoy the MUSIC NOT DISTORTIONS,

Dear @cal3713 : Great speakers you own, very good overall design and hard to beat.

Many of us almost always " want " better quality performance levels in our room/systems and many times through different room/systems changes " up-grades " we think we achieved that " better " whole target and normally what we got was more than a better quality levels a " different " quality levels but not necessary better one. We try to achieve what we like that not necessary means is rigth.

As you I tested several caps in my speakers and made comparisons through the tweeters caps: 4.7 uf. Mundorf, Jupiter, Duelund, Jantzen, etc.

My MUSIC/sound prioriites/targets are different from yours. My main target is to stay truer to the recording and performance must be in the neutral side with the natural MUSIC color, very good tonal balance, efortless dynamics/power, fast transient and ryhthm and with the natural agresiveness of the live MUSIC event seated at near field position that’s where normally the recording microphones are " seated " ( 2-3m. ).
Live MUSIC means too the SPLs of live MUSIC event, way higher of what we are accustom too at home.


""" Smooth, sweet, and detailed without any grain or harshness. ........ preventing the tweeters from being aggressive, which has been a problem ...."""

""" Just beautiful, organic music . """

Well live MUSIC at near field position is everything we want but " smooth, sweet or organic "" and it’s agressive, brigth and sometimes with harshness. All these is live MUSIC that's my reference.

I’m not questioning what you like because our different targets.

The designer of your speakers choosed Mundorf caps for its neutral characteristic in that frequency range where according my targets it has when several audiophiles look the Mundorf’s in the brigth side when it’s not when compared with live MUSIC seated at nearfield position.

What you like is something that several audiophiles are accustom to where the performance quality is more or less like if we were seated at 20m-30m from the live source/instruments. Nothing wrong with that but it’s not my target.

At the end I choosed the Jantzen Alumen over the Mundorf and I choosed because has better tonal balance. No, it’s not so expensive as the Jupiter or Duelend but these caps are heavy colored, are not neutral as many people could think.

Always is more easy to like something colored than dead neutral.

Anyway, good that you are enjoying your system and this fact is the more important for you.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.
