I'm recapping a Nuance Famco preamp, ordered Panasonic FC to replace all small electrolytes. As for the 2200uf/50v, I can't find any Panasonic FC at a reasonable price.
I do find Nichicon FW. I wonder if they're supposed to "sound" as good as the Panasonic FC, or should I insist on FC or any better model. The Nichicon FW are rated 85c.
Thanks

Do you have the schematic ? I wonder where do you need 50v caps in that preamp. I like to use the 105c caps in the power amps , but in preamps I am very happy with 85C caps, anyway Panasonic FM , FR , FS and other and Nichicon PM, PW , HD and my favorite KA(audio cap).
Any good 2200µF 50V caps with good ripple current rating, low ESR and high temperature rating should be absolutely fine. If you can hear the filter caps, something is seriously wrong!
You have lots of great ideas to share. But only in threads not related to perceived sound. Why then add pointless noise?
If the large capacitors are a supply capacitor, the use anything you want.
You could always bypass it with a better sounding part like a smaller panasonic FC cap and some 100nF polyester capacitors. Maybe with large capacitors the high frequency response does change to a noticeable level (and this could impact noise levels), but adding something in parallel that performs better would remove this problem.

Don't you dare try to shut me down. When the Emperor has no clothes I will say so and keep saying so. Very poor filtering could
become audible, but that's an issue addressable by improving filtering to something reasonable, and/or increasing PSRR. The choice
between two reputable brands of capacitor is down to relevant ratings (ripple, ESR etc) and lifetime issues like temperature rating.
I'll repeat, if the filter cap choice between two quality brands with good ratings affects the sound, something is seriously wrong with the amp.

I have to decide between Panasonic FC 50v (105c) made in Malaysia, and Nichicon FW 63v (85c) made in Japan. I'm not sure which one would be better "audio-wise". These are the only two that I found that I can buy for cheap.
Which ones I should prefer?

Yeah.... just forgot.
Please remember me regularly to trust your statements over my own ears 😕
I quite agree with Mark.
Noise produced by poor choice of smoothing, is an issue that can easily be addressed.
I have found in the last 50 years of sorting out DIY repairer's errors in my spare time from work, that ears are affected by the emptiness of ones wallet after a transaction in the pursuit of 'improvement'.
