QSC RMX 850 Power Supply Caps

Can someone tell me by replacing the power supply caps from 4700uf 80v to 6800uf 80V will it improve the sound. I'm looking to get tighter bass and warmer sound.

It is something I've always thought about: Replacing the original caps for ones with higher capacity; I can't understand why QSC uses supply low capacitance caps. But I think it may improve amplifier performance if best caps are added. Yesterday I uploaded a RMX 1450 clon here in the forum, look for it at Solid amp thread. I put 6800uf in the Power supply. It sounds delightful.

The thread is called Common Ground Colector.

Thanks, what else did you do to it?

I did to it nothing else. No problem if you want to put capacitors with higher capacitance. In my QSC RMX project I used Four 6800uF caps (two per supply rail) instead of 3300uF used in the original amp so replace them. No fear.
