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?

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?

@analogphotog if replacing, its best to verify what uF and voltage caps you have installed now, and if it's helpful to know if they are stock caps or not. If its a used SLI-80, people change them. People sometimes go 1000v when less is not available. May not be necessary, check the caps you have inside now, first.   

Having owned the Cary SLI-80 Signature and the Cary SLP-98L tube preamplifiers, and comparing with friends, I've concluded one thing. Changing caps may not always be an improvement, it can offer a "different" sound.  It helps to know what you are trying to change to gain more or less of in the sound, if that makes sense.
