RE: Cables

I hate wall warts, but one reason why designers use them, especially in
Europe, is that if you can keep all voltages in the unit below 48V, you can
save a wealth of time in artwork, documentation and test-houses. To cover
most of the approvals, you only have to have the wart itself certified, 
(and
use it across a product range) :)

another thing to be careful of are devices using wall warts or line-lumps
instead of internal power supplies. Of course you need to be sure to secure
them well somewhere in the rack so that they don't go flopping all over the
place when you move it, because they break easily. But also realize that
wall warts are typically cheaply made and not shielded well, and certainly
not designed with a professional audio environment in mind. They radiate a
lot of power supply hum into the area around them, so you should be careful
to keep them as far away from audio cables as possible.

It continues to baffle me why some manufacturers use these things in fairly
pricey gear. there's just no excuse for that, imo.
