Because:
1) Choke in low power supply. No, this isn't the first one to do it -- Twisted Pear Audio uses small chokes in their low power supplies, for example, and DHT filament supplies have contained chokes for many years, but it isn't exactly "average".
2) TUNED secondary snubber network which as John has mentioned in previous posts can make a measurable difference with power transformer resonances.
3) Schottkys.
4) Lower value first C after diodes.
5) Extremely low DCR
6) Tested with specific components as a SYSTEM to be low noise, etc. This is a valuable and underrated aspect, IMO. Most of us don't even have the appropriate test equipment (or free time) to check things like transformer resonances.
