Wima FKP / MKS vs. Evox Rifa PFR / MMK

[jonclancy]

Hi,

has anyone compared the Wima FKP and MKS with Evox Rifa PFR / MMK film caps?

The application is in an external DAC (both power board and DAC boards).

Just wondering if either of them had any significant sonic signature??

Many thanks for your thoughts!!

Jon

hi

I use mks for power dac but wima say fkp beter ...

Much, much better.

Holy thread-resurrection, Batman!!

Yep, if you have a choice in the correct value, I'd go for FKP.

hi

I use wima mks4 1mf with elna silmic II parallel is good image ...

but when I use 0.74mf fkp parallel with silmic ... I sound loss harmonic !!!

my question fkp1 better or fkp4 ? and what value...?

FKP are detailed , dynamic, open. One of the best cheap caps.

Thanks for sharing this. I prefer FKP3 where applicable, e.g. RIAA.
Some years ago I got a batch of them which are 1 % tolerance.
Much better value than all those fancy boutique parts. There must
be something right with them as you can find them more and more
in today's most expensive gear.

Can anyone explain the difference between Wima FKP and MKP to me? Both are polypropylene - the page for the FKPs says they are self-healing and able to withstand extremely large pulses. None of those strike me as especially important for AC coupling in audio applications. Am I mistaken?

 

[ticktock]

FKP = solid film/foil
MKP = metallized

You will clearly notice the the difference in weight when you hold them in your hands.

BTW, MKP4s are single-sided metallized, MKP10s are double-sided. Prefer the latter if
if capacitance and space are sufficient but FKPs are too big.

Okay, thanks. So what is it that makes film/foil only more desirable for audio than metallized? Is the dissipation factor/ESR even lower?

 

[ticktock]

Short: you're right.

I love sound in dac 24bit ... power dac filter

100µF elna silmic II + 1µF wima mks + 10nf ceramic cap

This arrange very good for car audio ... vocal very fantastic ... bass fantastic & hi range is Relaxing

fkp is very Earache... Because I'm in my car near Tweeter...
