Cables SOV-Ds...
20.) The issues at stake here are the crux of the on-going debate between
the two "camps".
While I will admit that not all designers will take any subjective opinion seriously, I do know from my own testing and from a huge amount of reader feedback that some of my designs sound better with different transistors or power supply configurations (for example).

The Truth About Interconnects and Cables Tuesday, November 16 2004
Power Leads
The power lead (cord or cable if you prefer) is how mains power at 220V, 240V, 110V at 50 or 60Hz gets to your system. The specifics of the voltage and frequency are determined by where you live, and the available household mains provided by your electricity company.
There are mains cables (power cords) available that defy belief. Would you spend US $3000
for a 2 metre mains lead?
You can buy a very nice amplifier indeed for this sort of money, but they are there,
and someone must be buying the stupid things.

20.) CL
a.) Sounds better by using a different transistor… ok then why can't a
power cord make things sound different ?
b.) many people are buying the " 'stupid' things" …
can so many people be bluffed and fooled as you seem to suggest ?
or is there some true 'differences' they hear and are pleased with it

---------------------------------
21.) What possible effect 2 metres of flexible cable can have to
counteract the kilometres of power company's wiring is a simple
question to answer.
None. Or, to more precise, none whatsoever. I am not referring to cables with inbuilt filters or other esoterica here, just perfectly ordinary mains leads.

Bottom Line on Power Cables
I am still waiting for a "high-end" power lead manufacturer to
- supply me with some scientific proof of the advantages of their cable,
- and how they improve the sound.
I have asked, and have not received the information.
Nor do I expect to, since they cannot provide any sort of proof because they don't have any.
Conclusion
(…)
Compare this to the snake oil vendors.
As an example, they buy perfectly ordinary cable from an established manufacturer, clad it in some fancy heat shrink tubing, write their sales pitch, and sell it.
They might actually bother to listen to it as well, but there isn't much point, since it is the same wire as used by others anyway. Do you see specifications, measurements, or other factual data?
(…)
Claims that power leads and interconnects will magically transform the sound of your system are false and misleading in the extreme.
The various system components may be influenced by some combinations, but a well designed system should not care.

21.) CL Final comments
- No matter how long the power connection is before the power
input of a piece of equipment; the last , the very last portion or end of
the 'line' determines the characteristics of the signal.
Simple 'mains' have no way to substantially correct the end-results.
But by understanding termination principles and simple cable corrections, the 'mains'
will be able to 'correct' the improper characteristics of the terminated signal.
- Until the audio-world is able to understand high-end measurements and
some accepted 'units', by academia, of 'fidelity': that is some sort of
metrics for the various parameters associated with good-sound; the
publication of high-end parameters will be of little use.
