[sdiy] Power Supplies... Whutchugot?...

[Tim Ressel]

Drew,

I cannot think of a worse power supply to use.
Switchers in general are noisy and therefore
unsuitable for audio work. PC power supplies tend to
be VERY inexpensive designs and have little in the way
of noise mitigation. 

My personal favorite power supply for audio stuff is a
surplus linear like Power-One. Making your own power
supply is fairly easy and not too costly.
