Using more capacitance reduces voltage ripple. On the other hand, using more capacitors of a smaller value (yielding the same total capacitance) may sometimes improve performance if the combination produces less ESR and ESL (equivalent series resistance and inductance) or features a higher total ripple current rating in comparison with a single capacitor.
if it is a Class D amplifier then i believe that you need a very very solid power rail supplying it....so you will need a power supply that can give you +/-70V with no more than say 300mV maximum undershoot or overshoot after a no-load to full-load transient and full-load to no-load transient.
if its class d then theres no way itll be drawing 5A continuously.
However, as mentioned class d needs well regulated rails with little over/undershoot, so you will need more than what your trafo can give, as the other contributors said.
