What's the Toughest Branch in Electronics?

Examples:
Smps design (switchers for..everything!)
Audio design (power amplifiers, analogue filters)
RF design (radio transmitters, receivers, radar, cellphones)
Digital design (computers,microcontrollers,FPGA)

I'll guess this order of difficulty.
1) RF design
2) Smps design
3) Audio design
4) Digital design

Audio design.
Nothing else is remotely as involved in the details at the limits of
current science/technology.
The basic electronic design is not so arduous but from there the
development becomes increasingly more time consuming if the
requirements of the true audiophile are to be met.
For example whilst it is well established in the audio world that hand
soldering all components with 60/40 RA fluxed solder produces a more
'rounded' sound to the recordings of orchestral works made on a
thursday afternoon, it required years of research to add a 'vibrant
cleaness' to the sound by ensuring the solder resist was green and
manufactured by someone wearing red socks. Even as I write the purity
of the sound from CD and DVD players using lasers with a bandwidth
greater than 1pico metre is being questioned.
