Default Replacing caps in Threshold S/200

I have a Threshold S/200 amplifier. I don't have any problems with it but since it is 20 years old I'm thinking about replacing the PS capacitors.

The original capacitors are Mallory 15,000 uF, 80V. I found following capacitors in Mallory catalog that fit size-wise and have similar specs:

Cap (uF) ESR     Ripple   Catalog#       Voltage
17,000   0.033    8.8     CGS173U075W4C   75V
25,000   0.024   11.7     CGS253U075W5L   75V
15,000   0.043    8.6     CGS153U100W5L  100V
30,000   0.011   15.2     CGS303U100W4C  100V
Would any of these work? Should I consider any other brands?

While I'm at it, are there other parts that would be worth replacing? I read somewhere about updating rectifier diod in Threshold amps.
