I've been testing different capacitor brand these few days.. but somehow, i dun feel there is different between this caps..

So i'm wondering whether it is necessary to buy more expensive cap?

cap tested : Ruby ZL, ELNA RE3, PANA FM, cheapo Rudoycon . All in 470uF

wish to have a some discussion with you guys..thanks

jazzy your are right.. the so called el-cheapo Rudoycon cap work marvelously without any flaw. So i just couldn't understand, why people in head-fi or other site saying "yeahhh.. ELNA is inferior compared to Blackgate NX......" .

I've read article the important of low-esr cap for power rail and film cap for input cap. have tried it all, result is the same.

what other audiophiler thinks??
