I am planning to build a 2-way system powered by a Sure Electronics AA-AB33182. I searched the Meanwell site for a suitable SMPS and narrowed down on UHP-500-24, based on Amp specs. But I have no familiarity or knowledge of actual power supplies to be used in audio.
Please critique, comment and suggest better options.

For audio a supply has to handle a very bursty load current. Some aren't very good with that, the best datasheets for supplies show the supply's time-domain response to full current demand bursts which show how well it handles sudden load changes.
You can't just add filter capacitance to bolster up a poor supply, there's a maximum output capacitance for SMPS, they won't start up if you exceed this.
Having said that Meanwell are a well regarded brand, I suspect they have good performance with hard loads. Its wise to over-specify a supply anyway as they run cooler and last longer that way.

Any 400W or more @ 24V SMPS brands you could recommend?
You mean capacitors help with handling sudden peaks? How does one accomplish that? Is it a matter of having a capacitor in series or something similar?
The total power required is 4 x 100W = 400 W. The SMPS is rated at 500W. Is that over-specified enough?
