I just got 2 x 10000uf / 50v Keltron capacitors for the chipamp. Is there any possibility to use one 25-0-25 / 2 amps toroidal + 8 x 10000uf capacitor instead of 25-0-25 / 8 amps since all these capacitors contribute ripple current of not less than 3 amps each capacitor. Hence 24 amps of reserve current will be there to serve the rest of the circuit. What do you recommend.
Always the best way: prove it to yourself. Your comparison of one 10000uF to ten 1000uf should make these differences noticeable ... even better if you can use a 'scope and square wave generator = looking at the leading edge of the traces, should see some improved response times ...
Response times should anyway be with 10 caps rather than one big cap but sonically I would like to hear the variation. The try is all for using Silmic 2 caps since they are not available in 10000uf quantities there is no alternative. But i am looking to use Keltron in that place like probably 10000uf x 10 to get phenomenal bass and for rest of the caps Ill use silmic 2.
In this case the follow thread could be of interest:

This multi-cap verses single cap question might be a good test of the DIYAudio "Test & Measurement interface" ... be nice 
Would be the showed caps by post 231 about

in use by this EINSTEIN integrated amplifier, I would probably not come to this observed audible result.
I have yet to find a single Panasonic FM series capacitor that has copper leads. I have purchased about 30-40 different values and voltages. Not one copper leaded cap in the bunch.
My prefered for the the time being. Seems like they add an extra octave in the bass . Soundstage is deep and detailed.
Panasonic FM is scratch.
Panasonic FM have tinned steel lead wires. They are good caps but the FC are just a slight tad better (in audio) although specifications of the FM indicate the opposite. Both are good industrial caps that offer good value for money and they last. I use them a lot and never had one failing till now. If Matsushita would produce them with tinned copper wires I would not bother to look further. Unfortunately they don't...
Caps that "seem to add an octave" are suspicious. Caps should filter ripple in power supplies, not add octaves of bass.

Hi,
What is the most important for a cap when it feed transistor ?
ESR-ESL or capacity in curent ?
For example Philips/BC 104 or 136 are knwon for their high capacity in curent (and in datashhet the higher value the lower ESR) but they sound coldy with harchness IMHO ?
Where can I find the capacity in curent in a cap datasheet ?
cheers,
Eldam

power transistor, or small signal ...?
as for bigger supply caps, the new Kemet/Rifa looks tempting
Do you mean: curent for power transistor and ESR for small signal ? I don't understand...
Some industrials Siemens are famous too here for power supply stages because of their curent capacity but don't know if they sound well like the smaller Elna Silmic or KS muse I use for example near the discrete stage or opamp for example... And a Elna Tonorex is not as punchy and transparent as a Philips but has more natural sound !
If I have a look in an famous golded japonese poweramp : just 2 big caps of 22 000 uf /71 V... and press say it sounds good?!
have you a ref for the Kemett you talk about ?
Where is the value please I need to look at in a datasheet for current capability... is it ripple ?
