Cause looking at some of the better sounding commercial kit there are plenty of cap-obsessed designers. Do we need to compile a reference list?
i am sure there are a lot, what is the point?

i comment with reference to myself, you can have your own opinions and that is also alright....

capacitors are not subject to debate as far as i am concerned, as long as you are happy with your capacitors, then that is it.....

Im an old fart now Tony, wish that Im younger cause the man that I admire most is Elon Musk. Just think of it when he started Space X, Nasa must have been laughing their socks off but just look at where Space X is today & what Elon must have been up against when he started Space X zero background against Nasa's knowledge. Look whose having the last laugh now.


Cheers

You are right of course. Once you start digging deeper there are some unpleasant truths to uncover.

With some caps the year of manufacture is decisive. With most it is also the rating, both in voltage and capacitance. All very annoying.

And of course there is that mysterious system synergy.

Elon would probably figure out all audio mysteries over a single weekend. Sadly, he seems to have more important things to do for now

Wow. Just googled those. Have no recollection of ever seeing one.

Putting his genius aside it is his fundamental mind set that drives him to where he is today.

It is good here cause it was designed for speaker XO which naturally is good for DC blocking as music signals are being input to the amp. Lol

Here we are, I like the guy cause the joke : the cab in the space ! A rational engineer would have said cause all the technical information collected, better to have a roof and sealed windows for the driver ! But man hey : no roof

We don't know at this point if the cab have an audio system despite there is no air outside, lol !

And here is I wanted to say, it's very revelant with some posters : they show their titles, I'm engineer, etc... so I know, I made first class devices, etc ! That's a class feeling to say on a vertical scale you are an idiot. There is nothing smart in that attitude cause nothing is about science with this attitude and too much engineers don't know enough about epistimology. Btw that's why they are not most of the time NOT scientists too. Nothing bad here, it's a reflex of human being when they don't master and are in the inconfort zone, their mind and tongue drift, me the first ! But hey caps are not so much rocket science nowadays, so they should calm down more about their behavior and just if they would like to do so take some time to investigate with more open mind. But of course, I'm the first to say, better to spend time to listen music ... which is all our goal here and we share the same good feeling about the music

But my feeling is their words about caps when some are outside the textbook here (rules they respect btw or the circuitry would not work) are also opinions.

And no, I don't think all the people we all know that had written about caps have said it all. I personally find the last I read in some known mag. here is quite limited with a cruel lake of imagination about the protocols. Just my pinion, of course, not a an universal truth.

Musk is a deer, sorry a dare guy that hits multidimensional and think outside the frontiers without raping the technical paradigms. His best talent is to take controlled financial risks. But huge risks... there is no great triumph (oh a cab yet!) without big risk !

So both frontiers of our audio caps world are opinions as far the circuitry don't break. When many think in an ABX tests that a devices, sorry a whole system, sounds best, without knowing it was capacitors optimized, then we are certainly in the collective hysteria, lol !

Indeed I had discovered that as well... but it's hard to identify cause also lytics are chemical... so sometimes it can be how we stock them... You can just know when you have bought the same ref in a short time at diferent authorized places in a short time windows : Mouser , Digikey, Farnell, etc.
