I'm sure this topic has been posted in other places, and please do provide links, but I've looked and the offerings seem somewhat sparse: There's no end to <$250.00 power cords, but I'm thinking those people who actually find some positive benefits to them are some of the few who either have awesome municipal power or have power conditioners or Dodd like balanced power supplies. I've seen the Majic Buss and this seems to be a relatively inexpensive start. But what about starting at the wall outlet? I have moved into a house where I'm not keen on tearing walls up to custom wire my listening room, but can I do something simpler like removing the common house ground, isolating it from the rest of the house, and give it it's own ground? After that (if that's even an option), what's the best way to clean up the power?
Also, once you have something like a Majic Buss or 'Power Regenerator', shouldn't you be able to use a quality power strip like a few I've seen on say VH Audio to get the right number of outlets you need? (I see some of those get expensive quick too). And then there's this idea that different equipment types (tube verses integrated, digital verses analogue, TV verses audio) seem to require a different type of power to optimize their performance. (I get this from seeing everything from the cheapo Monster power bars to Gary Dodds own Model 800 he currently has for sale where different outlets are marked for different types of equipment. Now I see that this can obviously be a sales ploy by the lesser companies, but when Dodd starts to do it ...)
What to do?

Dave, Dave here.
Good power starts at the panel. First, make sure that all of the connections in the panel that go to the room are clean and not oxidized. This is especially important for the mains cable drop that supplies the panel. One of the great sources of low level electrical noise is micro-arcing that occurs between conductors from loose or oxidized connections.
I would advise against a seperate technical ground. Ground to neutral potentials need to be the same and divided grounds are a no-no in that context. This is especially if you have video equipment that has grounds that are established at satellite or cable entrances. Many people forget that these have a ground connection.
The outlet is the next thing to look at. For many circuits I really prefer the Pass & Seymour 5262 Spec Grade receptacles. Other, more expensive units do offer a performance increase, but leave these to last as part of the fine tuning of the system. I have recently started using the Furutech outlets and much prefer them to Oyaide. I need to thank Jeff Glowacki at Sonic Craft for turning me on to these. Once again, make sure that the wire is clean and shiney before screwing down on the screws. I reccommend using the side screws and not back wiring the receptacles. It is easier to get a gas tight connection when you honk down on th0se screws.
Keep all of the blades on the equipment plugs clean and shiney... micro-arcing, again. I polish blades with a Dremel tool and Brasso. I really does make a difference that is easy to hear. This next part is very important: if you can't hear the improvement that these simple things make, either you need to upgrde equipment or there are other, more serious problems. I get my ears professionally cleaned once a year
After all of has been done, then consider the other units that you have mentioned. Of course I would love to sell you a MajikBUSS or UberBUSS, but get all of those other ducks marching in lock step before pulling the trigger on whatever gear you decide upon.
One final thing: don't kill yourself on the way to electrical bliss. If you are not absolutely confident working with something that can kill you, don't. Never, NEVER work anything hot and always use proper protective gear when working in an electrical panel even if you think it is denergized. When I worked in the semiconductor industry I worked with energies in the 500,000 to 1,000,000 electron volt range and developed a very healthy respect and fear for electrical current and voltage. My best advice is to do the same.
You will be amazed at what these simple steps will do for the sound of your system.
You will get a bunch of advice from these guys, so think about what will be said and don't be hesitant to ask lots of question.. You realize the need for good power and that is the most important aspect.
