Linear power supply Vs switching power supply for digital circuits and analogue circuits.
Is linear power supply more suitable for analogue circuits and switching power supply for digital circuits?

Switchers have the POTENTIAL to make high frequency noise that COULD get into your system. But like anything else, it is a matter of proper design and construction. Same argument really for linear supplies, they have potential to make hum. But I wouldn't blame an amp's power supply problems on whether it was switcher or linear. You can have well designed or poorly designed systems either way.
I'd use a switcher for a mostly digital thing simply because it is cheaper, more efficient, lighter. If I am building a high power amplifier, designing a high power switcher for it is beyond me. Certainly there are plenty of engineers who can do a fine job of it.
For analog circuits at line level, like signal processors, switchers are fine in my book. Recording studios, broadcasters, and other discerning users have rooms full of them.
