How much do caps matter-Cary SLI-80


My Cary SLI-80 integrated seems to have a faulty coupling cap.
When going in for repair, it seems that I should have all four done as another will probably fail in the near future.
There are many caps out there at many different prices.
How much do the different caps matter, and does anyone have a suggestion as to what I should use for replacement?

I don’t like responding without taking the time to give it some thought.

The Cary SLI-80 amplifier is timeless, it won’t die, and nothing has changed except the spelling of my handle-name, ...not, lol i caught it late only looking at the last post ;)

I’m just going to keep the old thread rolling… 
 

I’ve seen the Jupiter Copper Foil caps mentioned a lot, and they seem like a good way to go, but I’ve only seen them in .22uF 630V instead of 1000V. Is this what everyone has been using/is it safe to use them?
