Anyone have the Answer?

The only problems you can get into are not being able get enough current to a high powered amplifier and overloading a circuit by plugging too much into it. Number one you solve by running separate 20 amp lines to your amps and use low gauge power cords, 12 gauge will do. Number two is solved by running two separate circuits, 15 or 20 amp if you like to the system area and dividing the equipment between them.

Thank you scott22. You are absolutely right. It seems that people are scared of what they can't hear or see.

djones is also right. Any equipment with a decent regulated power supply will reject any noise. Don't buy equipment with bad power supplies.

Spending money on equipment on a lark just because you know you can send it back is IMHO silly. Expectation bias is going to make you think it sounds better when it does not which is why these companies bank on this sort of behavior. A company that has confidence in it's equipment will not accept a return unless it is defective. It's the old "Guaranteed or your money back" routine you see on TV all the time or there is a "sucker born every minute." If you get a power device flip to you phonograph and turn the volume all the way up. Is there any difference in noise levels? Sounding better can be an illusion. I can't tell you how many times people I know including myself initially thought something sounded better only to discover down the line that it really did not or even worse caused some kind of problem. If you think your phono stage it too noisy don't buy a power device, buy a better phono stage.

Always keep this in mind, the goal of any company is to make money any legal (sometimes not) way you can and lying about almost anything is called marketing (or politics). The audio world is loaded with scam artists.
Consumer beware.
 

Your AC line measures from the back of the device it is connected to all the way to the power station that generated it and includes any substations along the way.  All of it, the entire distance, picks up EMI and RFI.
I used Tripplite for many years in both the 4  and 6 plug models and for awhile the Isolation Transformer models.  I considered the Surge Suppression mandatory as I live in Miami and we get lots of summer thunderstorms. ..  and I actually lost two self-powered subs to surges.
I recently decided to finish off the system I have been building from time to time over the last 30 years and decided to add a high-end power conditioning system.  I had reasonable beliefs it would be helpful since I can hear a difference in background grain from summer when all AC units are running in the 167 unit building and a cool winter day when few or none are.  The power lines are also noise polluted by refrigerator compressors, computers, florescent lights and so forth specifically including lots of RFI from broadcast stations.
I purchased an Audioquest Niagara 3000 and a Monsoon power cord for it, and upgraded all the other power cords in the system to Audioquest noise drain types compatible with current requirements and the 3000. 

It absolutely has made a difference in background blackness, noise and grain in the sound and other areas but I would say this..  if the resolution of your system isn't at a level that you can hear differences in different interconnects, tubes and power cords look for improvements in other places first since you are still baking your cake and it's not time to put the icing on yet.

Try this: find a dealer who will let you audition one of those really pricy power cords. If the cord makes a noticeable improvement, your power is dirty and a "machine" will help. Good Luck!

I'll stick to my 4 26,000 mf filter caps per channel, per 100 watts times six (3 amps).
