These caps are used for oscilator circuitry.... ??

what does it do?

[jasonhanjk 0]

In layman term, creating a waveform of different frequency.

so that means it can change the way an amp will sound

If only you add them in your signal path. Normally it should belong in the power supply line.....

Capacitors change the sound. That's why different caps have different types of sonic signature.

But we all love distortion anyway. All audio equipment distort the sound. It's just which type we like. hehe...

I agree. One can change the sonic character of a cd player quite significantly by changing the type of capacitor in the DC blocking stage.

 

Among the moderately priced electrolytic capacitors, the Elna Silmic gives the best "distorted" sonic character.

Oh?

 

But I haven't tried Silmics. So far, I find that the BG & Cerafines are quite alright. Cerfines being quite affordable. Both are as good as each other, just different sonic signature. =)

I have tried the following as DC blocking caps in my cd player: -

 

Elna Silmic 100uF 50V - smooth with warm mids, slightly bloated lows

 

Elna Cerafines 100uF 50V - dynamic and "fast" sounding with a bit too much harshness in the highs. Prefer the Silmics over the Cerafines

 

Rubycon Blackgates Standard 100uF 50V - tight and deep bass, more transparent in the mids but a bit too clinical for my liking

 

Rubycon Blackgates F 100uF 25V - slight improvements over the standard Blackgates

 

Rubycon Blackgates FK 220uF 25V - sounds better than the standard Blackgates but it has the same clinical signature

 

 

If I have the time, I will be trying the non-polar Blackgates N series (if I can the values that I require)

 

I have a friend who owns a Rotel RCD-971 which uses Blackgates F 100uF 25V in the DC blocking stage. He replaced it with Silmics with great results.

Alternatively, one can use film capacitors such as Solens (cheap, but huge) and Auricaps ($$$) in place of electrolytic ones.

 

Results should be much better

Yes. But some applications require a large e-cap. So it's better to use the better films to bypass a good e-cap.

where can i find the Elna cerafine caps?

i found elna "starget" from RS they are red in color, are they the same as the Cerafine?

Burlington, well audio lab.

i tried that shop, they say they don't carry "japanese caps"

NO elna NO blackgates
