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?

Replaced all the electrolytics in a tube amp with 15 (hot) years on it, and it made a very nice sonic improvement - - all upside, no down, and no dramatic change in the overall voicing of the amp.  I hope you will be as pleased with your recapping.

My caps were not expensive high temp, low ESR Panasonics, FWIW.

If you can do the work yourself, the cost is quite minimal.  That's the route I took, but I am comfortable with a soldering iron, and the particular component had nice access to the capacitor leads for de-soldering (the hardest part!).  I opened up a friend's '70's Marantz receiver to see if I could pep that one up, and it was way too hard to get at the stuff, so "no go".
