I'm not sure about amps, but capacitors are so much better now. If you haven't already I'd consider upgrading the tweeter and mid range caps. Even the relatively bargain priced Mundorf MKP ( ~ $8) each would be a good way to go.
In the schematic I saw, I counted 3 important caps across the tweeter and mi, so around $24 in parts per speaker.
Also, the electrolytics in the bass are probably due for re-capping. Those are more sensitive, and you'll need to know the ESR's before replacing them.
Best,
Erik
