Buy cheap good quality commercial capacitors now and build.
Then you can experiment with expensive caps later if you still insist on spending money.

80% ?
allready fishy...
improves what figure by 80% ?

come on...
its snake oil.

say.. for powersupply buffer capacitors, might make sense to use low ESR rated ones, but mostly i just can't get that capacitor fever.
Same with input capacitors, plain-jane ones will do justfine till they are large enough.

Presumably you are using the PSU that goes with this design so stick to the 10K/100uF.

Similarly for C11 & 13, except that location is even more important.

One thing I can tell you is that Silmics are highly regarded for certain applications but not all! I don't believe that they are necessarily a good choice for chip amp power supplies.

With respect, it sounds as though you have become hooked on certain brands of capacitor, and are determined to shoe them in somewhere, regardless of the advice that you are seeking in this thread.

I would be using these speakers..
For surround tweeter: Madisound Speaker Store

For surround midbass: Madisound Speaker Store

For especially center channel:
The same tweeter as above... and for midbass..
WF160WA01

For subwoofer :Madisound Speaker Store

for center channel im thinking to use Silmics or im thinking to use for every other channel. Its for a commercial product.. do you think using silmics 2 is worth for this configuration?

Or for surrounds I might just use only full range capacitors.

The player in general which will be clubbed with this is this..
http://www.sony.co.in/product/dvp-sr750hp

The input capacitors for the each channel amplification will be the CTR Polyproplene capacitors even in the crossovers it will be the same...

The problem is im looking from musicality point of view but little bit skeptical to use silmics but since its just 2-4 dollars more and on an aggregate it would cost hardly 40 dollars for silmics and 40 dollars for two 10000uf mundorf Ag psu caps. So together im thinking to use it since it would make good improvement overall.

I am beginning to think that Nuuk has somewhat understated your attitude to DIY, it appears to me that you ignore everything posted by others !
