Thanks for elucidating Arny. Interesting what you say about Switch-Mode
Power Supplies (SMPSs). I've been dabbling in PC building on-and-off for a
decade and, when I last looked you could get SMPSs that were outputting
1.2 KW.

People like Crown and QSC have been building 5+ KW audio power amps with
SMPS for years.

I asked a friend, who owns a bunch of Perreaux gear and also builds his
own amps using toroids why he couldn't use a SMPS and he said "too noisy".
(A man of few words. LOL, I remember once we were in a discussion, a few
of us, and someone who didn't know him well asked him how he felt - He
said "With my hands". g )

Pretty much the typical kind of know-nothing, hate real progress, knee-jerk
response one expects from high end audiophiles.

Considering the price he was paying for big toroids (and that he was using
a few large caps anyway) I wondered why not just filter better and maybe
make a split-system, with the SMPS in a seperate box, perhaps on the
floor....

The people who build real power amps for real people have been using SMPS
for years. They were scooped up by people who did crazy things like move
their equipment around from place to place and worried about what it
weighed.

I suspect that the traditional power supplies were cheaper than SMPS up
until the past year or two.

Now adays you can't even buy a router or a portable MP3 player without a
SMPS wall wart. Solid evidence that they are just plain cheaper.
