Default Electrical Line Noise and Home Theater

If anyone recommends a product from Monster Cable, then save
yourself - run for the hills - every man for himself! Notice
how irresponsible that protector recommendation; based only
upon total technical ignorance - and maybe greed.

A surge protector claims noise reduction. Then we look at
the specifications - especially the numbers. Reduction so
trivial as to be virtually zero. But those who recommend like
an electronics salesman cannot be bothered to first learn
basic technical facts. They hope you never ask for numbers.

Want to increase AC electric line noise into that system?
Install a computer grade UPS. In battery backup mode, the
noise will be maximum - a good test of the noise reduction
that must be part of your existing satellite disk system.
When not in battery backup mode, UPS connects electronics
directly to AC mains where electricity is cleaner.

Address the problem at its source - the receiver, antenna,
or (start here) interconnecting wire. There is no magic
plug-in solution for this hardware problem. But 'magic
solutions' such as those from APC are so profitable as to be
recommended routinely by electronics store salesman.

goes away.

I read up on this on the net and it appears that a good powerbar/surge
protector with proper noise filtering features should do the trick.

In my shopping, I have come across the following options, an APC
SurgeArrest 11 plug power bar, that "absorbs line static, noise and
small spikes, EMI/RFI Noise rejection (100 kHz to 10 mHz): 60 dB" for
$22 at Costco or the Monster HT800 that features their "Clean Power"
solution for $139.

Now my obvious question, should I spend the extra bucks on the Monster
solution if in the end it does the exact same thing (give or take) as
the 1/5th the price APC product? I can't find any further literature
on the Clean Power thing, but I'm wondering if it just does the same
filtering, maybe a bit better, then the APC one and they're simply
giving it a jazzy name, fancier package and selling it for a whole lot
more? Will I really see a difference in terms of video/audio quality
between the two?

By the way, I know this isn't a home theater newsgroup, but I figured
the folks on this NG would know more about home wiring, electrical
questions, etc. and that you would be less fanatic about your home
theater solutions then in the specialized newsgroups where they will
most certainly tell me to get the more expensive product.
