A large choke is used in a purpose designed Choke Input Power Supply to more effectively filter incoming AC noise and stabilize the DC output than a more simple Capacitor Input PS.
It's a whole lot of fun to tweak and learn about changing the voicing of electronics to suit your preferences. May I suggest getting a cheap Chinese DAC to experiment and learn hands-on modifying first, before tackling something as expensive and well thought out as a Yggy?
Its a good idea, well I actually have a Tascam ADC Ive been experimenting with, and I built my own bridge rectifier and lm7812 regulator and 220uf cap and 0.1uf ceramic cap for the ADC.. and my measurements are damn good compared to a switch mode PSU. (I also powered the tascam adc with 1.5v batteries in series to get to 16v, and measured, and damn interesting how jitter tests goes with that) until batteries didnt provide more power to get lm7812 to regulate power.
My next project is to do lm7805 regulator, and power my chromecast to do jitter tests and see how that compares vs battery and transformer through same regulator.
I dont have intentions to modify my yggdrasil, just wondered if changing the regulators would achieve something, but then I read about different techniques to use normal regulators to lower noise floor, and Im sure Mike designed the regulators in Yggdrasil with as low noise floor as possible
Sorry I made you guys discuss changing caps in Yggy.
