Capacitor replacement for Jamicon 25 volt

What’s it for? The upper voltage rating doesn’t really matter as long as it's higher than specified. 

Any of these Nichicon are an improvement. If the existing cap is rated 25v 85°, go for 63V 105°C and you should be fine. Check for size.

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.
