Silmic II or Nichicon Muse KZ?

Jun 5, 2008 at 3:47 PM Post #2 of 19
Nichicon "FW?" Not aware of that one - AFAIK, they make FG's, ES's, KZ's, FX's as "boutique", then quality power caps are UPW and UHE.

As for which is better, are you applying them in the signal path or in a power supply?

not a simple question at all ...

Yes, well - the Sigma22/11 has no need of boutique caps.

A Panasonic FM is the lowest ESR and Ripple cap widely available, although the Nichicon UHE equals it in some sizes.

Notably, Panasonic FM's are only available up to 50V, whereas the others go higher. Higher voltage usually means even lower ESR for the same capacitance, by the way. However, if all you do is increase voltage to 63V so that it equals a 50V FM, that may not be a good tradeoff.

EDIT: Just guessing.

wnmnkh, now that you have the answer, why don't you share with the rest of us, and answer the question from tomb, signal path or power supply? Has anyone read the 21 capacitor shootout? Is it better if possible to avoid capacitors as a coupling device between amp and load? Perhaps transformer (monoblock)?

it is better to avoid more stuff in the signal path, although the effects of said stuff can be minimized or at least controlled if carefully selected.

As far as whether a transformer or cap is better, you just opened a can of worms. they dont generally lend themselves to a similar enough circuit to really make a solid comparison. it is NOT like the cap shoot out where you can take a bunch of caps, and just swap them in the same spot on the same amp. both components have their advantages and disadvantages.

So I guess the guy who started this thread was looking for a cap to help smooth and strengthen the DC supply, to avoid ripple in the DC current as it feeds the amp device. Are the FM and Muse caps low noise also? How much of a factor is electron noise in the selection of caps, or any audio device for than matter?

What about Panasonic FC? I never checked to tell the truth but always thought that it have the lowest ESR.

Vishay Sprague Solid Tantalum
0.045 to 0.1 Ohms at 100KHz measured ESR. I've seen these used parallel (bypassing) Panasonic ECWU Series in some highly respected amps' power supplies. By highly respected I mean on this forum (Head-Fi)

Low ESR isn't really that big of an issue unless your powering with less than 5 volts battery anyways, and even then only from a standpoint of battery life, or the lack thereof.
Where in Chicago are you, and do you live close to Ray Samuels? I live close to South Bend, IN.

I'm in the far-west suburbs, so no, not close to Skokie.
