capacitor bypassing/cascading......

Too late to edit. New comment.

My experience with the cheap NOS styroflex aka polystyrene 10 nF 600Vdc:

Tony Gee's Capacitor page updated..

The burning is very fast, as you can see how the sound is improving. More detailed sound and, above all, much greater separation of instruments in jazz. There's even a little more depth - you can tell if I get up and walk away. Ah, despite the greater detail the treble are more pleasant .

The classical music is also improving a lot.

The boxes look like others, the music is more real, credible .

On a scale of ten, the score would be:

Before: 8/10

Now: 10/10

I guess with commercial music the improvement will be much lower.

Ah, the Believers looking at the sky trying to find meaning in the cloud shapes.
And of course finding it 🙄

Thinking that a .01 or even .022 uF cap bypassing a good or even average 3.9uF cap can do anything audible takes more than plain Faith, but won´t delve into that out of respect.

Just remember they have respectively 390 and 177 times HIGHER impedance, at any frequency, than the cap they are "bypassing" .

Can that justify wild unsubstantiated claims such as?:

I know this is a highly controversial topic. Bypassing for me does work. I use it all the time on dac, amps & crossover by I prefer to use a value of 0.47uf somehow it's more balanced
Another thing one must look at is sound, all caps be it Boutique of Regular will have certain sonic attributes. I use different brand of caps in the mix to balance or attain the type of sound that Im after.

I'd be glad to act as a landfill for all those cheap 10 nF 600 Vdc PS capacitors that you've replaced by your super audio grade PIO/PPIO capacitors. Mind to send them to me?
And what's this white rectangular thing at the lower border of your first pic?
Best regards!

How much farads in the bypass cap?

It is better at least 1/100 value than the big. And, important, is cheaper! An example with KEF Q100 crossover.


Bypass with 0.022 uF aka 22 nF

3.9 uF + 0.022 uF = 3.922 uF

An externally hosted image should be here but it was not working when we last tested it.



Bypass with 0.220 uF aka 220 nF

3.9 uF + 0.220 uF = 4.12 uF

An externally hosted image should be here but it was not working when we last tested it.


The crossing point shifts slightly to the left and changes the SPL graph a little.

...The ClarityCAP CSA alone is natural but edgy, definitely not good. The ClarityCAP CSA+KZK K78-34+Miflex KPCU-01 gives the best harmony.

I also tried only the ClarityCap CSA+KZK-K78-34 but was missing the micro detail with the soundstage and the global warmness. Yes, the Miflex is very important and with such a small value is a strong influencer in the sound.

The result:

Extremely butter-liquid-silky smooth with huge soundstage, with rich organic micro fine detail. Unbelievable experience. We listened many different kind of music, classical, jazz, disco, latin and simply fantastic. We always turn the volume up

1 - Capacitor bypassing was a tried-and-true cost saving method for power supply design. You could combine cheap, high inductance wet caps with some film bypass caps to get a much more cost effective cap with no high frequency inductance. Back when I was doing this in gear wet caps were not nearly as good in terms of low ESR/inductance as they are today. For instance, the Panasonic FM line didn't even exist yet. 🙂





2 - Based on advice from SpeakerDoctor (RIP) I experimented with Clarity MR + Audin TC caps. My experience was that the smaller values ( < 5uF) did not benefit from bypassing, but that larger values did. I used Audyn TC caps in the 0.1 uF range. For $20 a piece, worth experimenting with and coming to your own conclusions.



If I had the cash to re-do this experiment I'd try making up a 10uF CMR out of multiple smaller values, but time, money are hard to come by these days. 🙂





Please take this as friendly, moderate advice.

Although someone doubt, I have enough technical knowledge on electronics ... but not focused on audio. Hence, I was so reluctant at first, testing with cheap polystyrene capacitors to verify for myself what so many comment on the network. I noticed the difference but my companion did not, unlike what happened with the ferrite and the spectacular change.

In Spain we have a saying: los experimentos se hacen primero con gaseosa / experiments are done first with soda.

Now I have exchanged for other audiophiles, but reasonable in price due to their small value so as not to discourage me from doing the test. We were both surprised by the difference. And that person also has electronic knowledge, but not specialized in audio. None of us find a logical explanation based on our knowledge and that has always bothered me.

On the open internet, since its massification, good education and respect is a good that is scarce more and more unlike what happens in the other, where I participated/participe before. Years ago I decided not to create content with substance in open and less in Spanish (the new generations are very disrespectful and ignorant - the decline of the Spanish education system is undeniable).
