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.

That is a great question. I really appreciate you guys help and will look into those caps.    I will need to detached the card it's attached to.  It's the black cap pictured at the bottom in the Bic.   https://photos.app.goo.gl/mmcSzcQZ81sEAFwi8

@noromance i have been out the game and new to ht.  All of this was no hear and pure reviews.  I am not aware of HT gear and was expecting more since their were so many reviews on this unit.  Had I known I would have save up for something else but what??  Which is the question, this was the best Ive researched for HT and reason I bought it.  Supposed to be the creme de le creme in HT.  Anyway keeping it in perspective, this is HT.  

Thanks for your suggestions.   @at Jason  I won't wait my time elaborating AGAIN on non help intent!  I can see you may not be comprehending thoroughly which is not important to me!  Anyway,  That Jamison cap is a electrical cap.  Don't know if that will be worth it?

Qui k update.  I finished modding the Onyko tx-rz50. Changed out all the cheapy parts, soldering and all. This is a first class component, the video was already good, now it has Rich vibrant Colors and 3d imaging really impressive.  The audio hold its own with a very low noise floor.  Pretty black.  It might not have the most lushful sound but very clean, black and very nice detail.  Worth the head ache to upgrade.
