Default The big capacitor audio myth ?

Hi fellas .

Probably not the first time someone has this question but after some googleŽing i have no solid answers . People claim that each capacitor has its own character and "the other group" say that there is no scientific proof about these claims .

I owe two similar models of vintage marantz , one has "crappy" caps like jamicon and some Fuhjyyu caps ... Other one .. low z rubicons i think and nichicons . I use both with my grado-500 ps and i cant tell the difference . (marantz 1072&1070) It really got me thinking .. im very picky about audio quality .

Im wondering if the audio capacitor myth is still going strong ? Is it a nasty herbalife scheme to make more revenues for the capacitor companies ?

hope iŽm not making you bored

Personally I usually use the cheapest Chinese capacitors off ebay and have never had a bad sounding amplifier.
I guess other factors might have more of an effect like speakers that vary wildly in impedance across the audio range.
Not much point in 0.00001% distortion at the amplifier if the speakers distort by 10% !

What about capacitor sound makes it a myth? Seems to me to be just that the noise on supplies is more audible than people believe. More caps (lower impedance) makes for lower noise power hence cleaner sound.

PS I also use the cheapest Chinese caps I can find - the more the merrier.

Meaning ceramics? Sounds expensive, would be potentially awesome though

agree with this 100%, any designer worth his salt will use capacitors as they are designed for, not because audiophools says those are the caps to use....

the challenge to designers imho is to come up with designs that rocks and is the biggest bang for the buck at the same time....

Looks promising - how many uF do you have there? Any series L?

Perhaps its time to change my sig to 'There's no such thing as too many caps'

16 x 470ufd....after the bridge rectifier, 2 x 470uf, then to the choke, and then after the choke is the rest of the filter caps.....

these caps were pull outs from smps psu boards and checked out good so i used them...

the owner of the preamp insisted that i use all those caps....i made 3 preamps all using the same psu topology....

Must be fairly high voltage as those 470uFs look to be snap-in types? My latest buffer has 91 * 4700uF on the rails, but only 6.3V.
