Actually, before SMPS's came out , this would be 100 Percent Dead on
correct.
The SMPS used widely in this day and age has a Built In Oscillator that
throws a 'monkey wrench' into the mix when Frequency shifts and Voltage
Shifts
really swing considerably. Rare ? Yes - but with the growing problem of
inadequate Electricity / Shortages in this Country in alot of States, I
think you will be seeing more of it.
We were recently hit with an outage due to a damaged main power Line. The
Damage was such that it wasn't large enough to cause the protection /
overload
system at the power Co. To trip. So we had the Lights lit at about 40-60% of
their maximum normal rating for about 15-30 minutes. At what Frequency, I
have no idea. Whatever this condition was, it was enough to cause nearly
every VCR or TV with an SMPS to become damaged. On the Few Units I was given
to repair, I found the Electrolytics off the bridge Rectifier had "peed" out
the electrolyte.....and was essentially an open. Replacing this seemed to
restore operation of the unit.
I have also seen other cases, but not in this instance, where the
Electrolytics on the other Side of the SMPS, leaked prematurely. Now weather
the unit had seen a similar condition as this, is speculation, but possibly
true. Its well documented that Hi-ESR Caps are required in these
Applications.....and now I really see why.

I'm not an expert at this overpriced stuff either, but would agree with
Damon.
I have seen no difference in using regular Audio/Video patch cords
($3.95) over their Gold Plated patch cords for ($21.95)
Basic Electronics tell me that most solid state components do not work
well with raw A/C. So if you want to buy (or sell) Line Conditioners at
1K per pop, may consider investing that money and open a BMW Car
Dealership.

OK, AC gets converted to DC in all Stereos, TV's.........even
microwaves......so.......so what if AC is "spiky"? It all comes out in
the
capacitors, SMPS's etc.
I wouldn't buy it, nor would I purchase their high-priced cables, or
their
"conductive juice in a bottle" stuff. Audiophiles suck this stuff up,
and I
know 1 or 2 in a group of 3000 to 5000 regular customers, so it ain't
worth
it.
