8. The Power
Conditioner Lie
Just about all that needs to be said on
this subject has been said by Bryston in
their owner’s manuals:
“All Bryston amplifiers contain
high-quality, dedicated circuitry in the
power supplies to reject RF, line spikes
and other power-line problems. Bryston
power amplifiers do not require specialized
power line conditioners. Plug the
amplifier directly into its own wall
socket.”
What they don’t say is that the same
is true, more or less, of all well-designed
amplifiers. They may not all be the Brystons’
equal in regulation and PSRR, but
if they are any good they can be plugged
directly into a wall socket. If you can afford
a fancy power conditioner you can
also afford a well-designed amplifier, in
which case you don’t need the fancy
power conditioner. It will do absolutely
nothing for you. (Please note that we
aren’t talking about surge-protected
power strips for computer equipment.
They cost a lot less than a Tice Audio
magic box, and computers with their peripherals
are electrically more vulnerable
than decent audio equipment.)
The biggest and stupidest lie of
them all on the subject of “clean” power
is that you need a specially designed
high-priced line cord to obtain the best
possible sound. Any line cord rated to
handle domestic ac voltages and currents
will perform like any other. Ultrahigh-
end line cords are a fraud. Your
audio circuits don’t know, and don’t
care, what’s on the ac side of the power
transformer. All they’re interested in is
the dc voltages they need. Think about
it. Does your car care about the hose
you filled the tank with? |
