Do you hear any hum with your ear close to the woofer ? If the answer is yes, increase the PS cap size.If the answer is no, may I suggest that you DECREASE the size of the PS caps. Use several small high quality caps in paralell, close to the output transistors. The amp will sound much faster and cleaner, specially in the bass and midrange.
Most high-end european manufacturers have abandoned large can caps, they have too much series resistance and series inductance.
Do a google image search for Gryphon or Eectrocompaniet amps.BTW I believe this tweak was pioneered by Steve McCormack, he calls it Distributed Node Capacitors or words to that effect.
good luck
