prone to noise?

(1/2) > >>

uranium235:
which is prone to noise switch mode or linear type power supply specially when used in audio equipments?  ???

saturation:
Switching.  Even lab grade supplies have more noise than a cheaper but well made linear.

uranium235:
is it possible to reduce or eliminate the noise in switchmode?

Kiriakos-GR:
No , simple as that ..

Thats why any audio device coming from the respectable manufacturers,
uses high quality transformers , with shields and all . 

slburris:
How about running a switcher to slightly above the voltage you need,
then use an LDO linear regulator to get the final voltage?
