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.

Epcos Sikorel and Nichicon KW series are also outstanding.

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?

Yes they can. I have some impossible to find Elna Cerafine caps that I subbed into the power supply of a Son Of Ampzilla for just this reason and the difference is a blacker back round with finer transients and deeper sound stage. The amp sounds faster. The originals were Mallory. This was in a recently rebuilt amp so all the parts were new which represents a fair comparison.
