Ethan, lucky for me its not you who determines or justifies my"overspending" habits; some of us simply don't have the luxury of being right all the time.

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.
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!

Read the specs, there is a big difference between some crap consumer stuff and legit commercial stuff that is built to a standrd, UL ETL, etc...Specs matter...

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. :mad: I can't find any technical info on the box they attach to the meter outside. Anyone here have any knowledge of these?

Here we are talking about power conditioners of five digit price tags, while I got flamed hard by PC building cheapskates when I suggested paying ~40 bucks more for computer PSUs with better build quality, efficiency and warranty length is a good idea. :rolleyes:

Yep, I think that's what it is, or something like it.
When you think big picture, if this a viable protection product, why isn't it just included on the installation of everyone's service and not a extra charge addition. If you know you can make your service safer for the end user why not ----------------

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 violation
