If your caps were compromised; it should sound better, soon as you get it back. Chances are good; it will sound(increasingly) better, as the new electrolytics, "form", their oxide layer. https://en.wikipedia.org/wiki/Electrolytic_capacitor
Expectations after re cap of power-amp
My 1982 Yamaha M-2 power amp is in the shop and this time I agreed
to replace all the suspect capacitors. Two
of the capacitors are the size of coffee cans and the total bill may exceed
$500. I am told that since all the
replacement parts will be as good as or better than the original parts it should
sound as good as new or better.
I’ve never done this before. Should I expect “as good as new” or am I completely wasting my money?
