VERY nice! That is the way to go for the Hypex modules, also the UcD. I do a similar power supply for my Reference amps, but I use 23 different capacitor values, but only two of each value, whereas it looks like you've got more than two of each value.
One additional trick I use is that I use a LC resonator tuned to the sampling frequency of the module. This adds a little of a "jitter flywheel" effect to make things even smoother.
Let us know what the amp sounds like. I'm guessing that it will be quite spectacular.
