Upgraded power supply Caps?


Hoping to get some input on power supply capacitors. I had a cap in my Classe CA150 burn that is for the preamp signal in the power supply. What I am curious about . Can better or different caps improve bass definition and or response. I like the sound of this amp in my rig however the area I believe is lacking a bit is the bass. The extension and weight are fine but it could be more defined. So if anyone knows if caps can help please advise.

Csontos Thanks for input. I will look for the Elna caps in the values I need. If I can not find them I willcan look for another high quality brand. Anyone else with recommendations for good Caps?
