Replacing caps for Cary SLI-80 Signature

I need to replace one of the Jensen copper foil, paper in oil caps in my Cary SLI-80 Signature. Is it okay to just replace the one, or should I do both on that channel or possibly all four (both channels).

Also, I've read some reviews that recommend not using these caps because they are unreliable. But I haven't seen any that have a better recommendation for this amp. Even the Formula-1 uses them. Does anyone have recommendations?

Thanks!
Chuck
