Since no body has really answered your question I will take a stab at it...
I would say (total capacitance being equal) the smaller number of larger value caps would perform better because the larger plate area would have a lower ESR. A single very large capacitor would be best.
I still do not understand what people here mean when they talk about caps making amps "slower". Power supply filter capacitors are like an "energy bucket". Besides smoothing rectified DC. They provide a local storage of bulk energy for the amp to use during fast transients. (like a loud orchestra burst) If the capacitors in your power supplies are too small your amp would be power starved and clip during loud music bursts, even worse at loud listening levels.
