Hi Guys,
I was debating with a friend about linear supply vs switched supply in products.
It is my position that the only reason to use a switchmode supply in any product is for cost effectiveness.
Weight of the supply could be included in cost effectiveness for shipping, etc.
It also occurs to me no audio equipment has switched supplies,
and for a linear supply you have a pi filter, and only have to filter the mains frequency.
I understand a switchmode supply can have the money spent on it, and have good filtering,
but that was all for noise the supply made anyway.
Is all this correct, and is there any benefit at all of a product having a switched supply?
