First of all, if you have specific questions for me, its best if you email me at frank@avahifi.com. I do not check my Audiocircle mail every day.
Regarding current capacitor of the SET 400, each channel has four double die 20 amp, 200V, 200W rated Exicon power mosfets, plus two more big Exicon devices per channel used as regulators. The maximum recommended speaker fuses are 8 amp quick blow types that support full power (225W/Ch into 8 ohms, about double that into 4 ohms). Bigger fuses equals blown speakers saving the cost of replacing fuses.
An interesting fact regarding the regulators is that at low output power there is high voltage across the regulators, but low current so very safe operation, and very high power there is low voltage across the regulators, but high current, and still very safe operation. Pretty fool proof operation.
Some other companies might just add up the current rating of all their output devices and tell you 20 x 8 equals 160 amp current rating. That is BS.
In other words, the SET 400 will drive cleanly your system as loud as you desire, short of breaking windows and eardrums.
