I wonder if one of your opamps are oscillating. Would you please double check the temperature for each opamp? If you don't have an IR thermometer, at least use your finger after 30 minutes of music playing with case closed (then open up the case and check then the temps).
I would suggest you to address this issue to BURSON, maybe they can accept a RMA.
However, if you really want to replace them, please post back what models you found. I would personally suggest you Nichicon UCD or Nichicon UCB, but I guess Nichicon UCH should do as well.
Increasing capacitance values above the original values might cause MCPS regulators to oscillate, so I would stick to the original values, unless you have a scope around and you feel comfortable to record and check for any possible power rails ringing after power-ON and also check for PSU oscillations.
Good luck and come back with good news!
