I do Mod for switching power supply
for The DENON DVD 3010
what is the best 47uf 400v-450v capacitor
for the cap after the diodes bridge
in the psu ????

I know bro
I need a recommendation for the best capacitors
I want to build hi and power supply for the denon 3910
I chose diodes
for Bridge diodes
Of PAWER INTRRATION
QSPEED
naw i need 47uf 400v cap the best one

Parallel 10 of these 4.7uFx630V caps for the best sound.
Duelund Capacitors_ PIO 4.7uf / 630VDC
If you can't afford it after all, this one is cheaper:
(CCESA-460)- 47uF 630Vdc Claritycap ESA Range polypropylene Hifi Collective

Measure the amp performance with the original cap in your new PSU, then measure the amp performance with the new cap in your new PSU.
Publish the differences.
It might be instructive.

Stick with caps made for switching supplies from major manufacturers (and sourced from reputable distributors, not EBay). Like pws said, low ESR, low ESL, high temp rating. If you want to waste money on "audiophile" caps, use them in the analog portion where you're unlikely to unintentionally damage something.
Does not matter.
Chokes are best power reservoirs for analog applications.
Foil caps comes second.
For low voltage hi current SS applications chokes and foil caps are unpractical but Black Gates (Elna, Nichicon) do the job well. Low power SS applications mean low current might be treated somewhat similar however not as efficient as hi voltage low current of course.
BTW foil caps and chokes make sense for DC circuits right before analog active components.
Placing them in switching part will cause more efficient RF noise.
Listen 😀
I finished the improvement of audio circuit DENON DVD 3910
And came out perfect
Now this second phase of the overall projectl
i planning
To replace the diodes
In the diode bridge to QSPEED diode
of company PAWER INTGRATION
I need the best possible capacitor comes after bridge diodes
47UF 400V

Unless you know exactly what you're doing (and are confident that you understand the engineering better than the guy who designed the supply), leave it alone. Switching supplies are very tricky and naive mistakes (like replacing parts willy-nilly) can easily cause explosions.
keep in mind that you will be working on the mains side of the circuit, if you are not trained to do this, better not.....death from electrocution is permanent...I am an electronics engineer
Famous last words.
Don't screw around with switchers unless you have particular expertise in that specialty.
Well honestly I cannot see any issues with replacing 470mu 450V cap with another 470mu 450V cap once polarity is preserved right. An there is a fuse in front of it anyway.
Major question what is the point?
All audio ethereal related tweaks should be implement after switching PSU not in the switching PSU by itself.
