I have seen plenty of examples of people overspending on audio "gear."
Running Balanced AC power in a residential environment violates the NEC , it's used in commercial settings, studios etc, where the components are labeled properly, so no one gets surprised, and you must use equipment designed for it. Using Balanced Ac power on home hi fi stuff will kill you, you are energizing the Neutral leg as well as the hot leg, big no no. That's why there is a hot, neutral, neutral is the grounded conductor, it is not meant to be hot, so the chassis is hot, lots of leakage current ZAP! Especially if you have a 2 wire cord, with no ground, ZAP!I'm still alive here.
I've found no "hot" spots on any of my gear. I don't expect any to develop.
I follow the precaution of not connecting unnecessary items to balanced power.
As I understand it, the outlets are (Dual Pole?) GFCI protected.
I suppose I could run a GFCI triptest on both legs, and see what happens.
"Equi=Tech was started by Martin Glasband to manufacture Symmetrical Power Systems. Interested readers should check out Glasband's November 1994 Mix article "Lifting the Grounding Enigma," also available on Equi=Tech's Web site (www.equitech.com). Glasband is also the author of National Electrical Code Article 530 G, which allows the use of balanced AC for audio and video systems in the U.S."
I can't see all of the labeling on the back of my unit, but it is ETL listed...
Is the ETL Listed Mark legal equivalent to the UL Listed Marks?
Yes. The true legal requirement to test and certify products for sale in the United States is a designation by the Occupational Safety and Health Administration (OSHA) as a Nationally Recognized Testing Laboratory (NRTL). An NRTL functions to provide independent evaluation, testing, and certification of any electrically operated or gas- and oil-fired product.
ETL is recognized as an NRTL in the United States and, in a similar capacity, as a Testing Organization and Certifying Body in Canada by the Standards Council of Canada. A product bearing the ETL Listed Mark is determined to have met the minimum requirements of prescribed product safety standards. Moreover, the mark indicates that the production site conforms to a range of compliance measures and is subject to periodic follow-up inspections to verify continued conformance.
What’s the difference between the UL and ETL Listed Marks?
Nothing. Both marks demonstrate that the product that bears it has met the minimum requirements of widely accepted product safety standards as determined through the independent testing of a Nationally Recognized Testing Laboratory (NRTL). And, as part of that testing regimen, the product manufacturer has agreed to periodic follow-up inspections to verify continued compliance.

I'll admit I was a little wary when I first installed it, but no problems or surprises have been noted in the five years I've been using it.
I can't find any technical info on the box they attach to the meter outside. Anyone here have any knowledge of these?
Of course you have no problem with blanced power on consumer products designed not for balanced power, UNTIL u do..when a component shorts to the chassis or such. Consumer products for houshold use are NOT designed for balanced power. In residential environment . you are putting 60VAC on the nuetral side of the transformer, Big violationRunning Balanced AC power in a residential environment violates the NEC , it's used in commercial settings, studios etc, where the components are labeled properly, so no one gets surprised, and you must use equipment designed for it.

Local Duke Energy power provider offers some sort of full home surge protection at the meter for a installation + monthly charge on the power bill. A number of folks in the area have jumped on this but as I see it, it's no more than a insurance policy hustle. I can't find any technical info on the box they attach to the meter outside. Anyone here have any knowledge of these?

Lightning has so much energy, it will vaporize that device in an instant. There is no hope of containing lightning.You can also see in the right-bottom a gas discharge device that will "consume" the extra energy coming from the mains, most likely when a lightning strike occurs.
I want to understand the various merits of mains power conditioning. I use a balanced tx but this caused problems introducing high gain! Why did that happen?
What's the best approach for your advantage audiophile? What's going on between the power socket and your system.
Try not argue, this is a resource thread not a pissing contest
Thanks
It will die within few uS for sure, but it might make a difference between a flaming varistor and a non-flaming one, although I can't test this.Lightning has so much energy, it will vaporize that device in an instant. There is no hope of containing lightning.
So mothers obsess with their alcohol intake when breastfeeding. Men obsess with the polution of their hifi power. And no evidence supports their behaviour. Just let the alcohol and music stream
The sacrifice/risk ratio is way out of balance between those two. If in 1 out of 100,000 cases both sets of people are right and yet don't obsess then the man just gets hifi that sounds a tiny fraction less perfect than it could. The woman ends up with a child with issues. But then again as messed up as people are today maybe they need more alcohol as babies.
