5000 hr 125 C rated cap life is much better than 10,000 hr 105 C rated cap life, if both are ran at 50-60 C you might expect even in a "hot" chassis

Google electrolytic temperature life derating

given better processing, materials today you should also be able to up the V rating in the same case size - also contributes to longer life, but not as strongly as temperature derating

if any Electros can be identified as being "in the signal path" then looking for non-polar construction with high V rating could be an improvement according to Bateman's meaurements

Thank you! that helps make the decision easier. Once i get the amp apart I will take a good look at what and where each cap is in the circuit. I doubt Krell would put EL's in the signal path. I Do see plenty of film type caps in there as well.

Is ripple current rating an issue for a 200uF cap? (as it sounds like a small value electrolytic, as opposed to a large electrolytic PS cap)
