Capacitor replacement for Jamicon 25 volt

It’s for the onkyo TX-RZ50 for HT. Everyone has been raving over it m, after research I bought it. It is unenvolving with no emotion or life, very stale. I dont get it. It’s made with the cheapest parts ever. It uses 5 cent power cords and has a 3 cent hdmi cord connecting to the arc hdmi internally, the shoes are plastic. I am using lessloss powercables, changed out Internal HDMI to iceage 2.1 hdmi, I sound proof it, waiting for Gold or Rhodium wattage iec that are cryo but these will not improve the sound signature or will it?  Looking for suggestions.I have very engaging fronts and center channel but the receiver is not doing it. When I look at the Capacitor I saw a little hope. I am not familiar with resistors and etc.

I Get it, I just got everything out of storage and this was the first thing I’ve listened to in 5 years or so. When it comes to speakers, Capacitor can induce a new sound signature with speakers...ie Elac debut 2.0 b6.2

My expectations was much higher from the review.

I can recomend Cornell Dubilier capacitor 383lx series. They sound good in power supply and have a huge number of voltages and values.

Nichicons are good too. I also agree than 63v is better than 25v if there is enough place in box. 63v from the same series have smaller cos Phy versus 25v.
