Who has dumped the power conditioner?

Is this supposed to be humor?

From a technical standpoint it strikes me as reasonably plausible. The inductance and/or resistance of the long extension cord(s) would help to isolate the system from sources of electrical noise which may be present elsewhere in the house. Running multiple long extension cords to different parts of the system, such as one to digital components and another to analog components, would reduce cross-talk of digital noise into analog signals that may occur via the ac power distribution arrangement, similar to what multiple dedicated ac lines might do.

This assumes, of course, that the gauges are adequate to support the current draws and run lengths, which offhand I would think may very well be the case for 12 or 14 gauge, serving typical components.

I'm not saying that it will necessarily be as beneficial in all systems as running dedicated lines from the service panel, just that Elizabeth's observations sound plausible.

I don't question anyone's good intentions here, and I certainly don't question the quality of the product. But it seems to me that as a matter of both common sense and basic good ethics, when a product is praised and the person praising it has a financial interest in its sales, that interest should be disclosed.

And upon careful reading of this thread and the one linked to by Kijanki, I see no denial thus far that such an interest exists.

The effectiveness of a balanced power arrangement, such as the Equitech provides, can particularly be expected to be both system dependent and unpredictable. That is because its effectiveness depends on the happenstance of how equal the parasitic (and perhaps designed in) capacitances between ac hot and chassis are, relative to the corresponding capacitances between ac neutral and chassis, for each piece of equipment that the balanced power is supplied to.

See the second paragraph on page 2 of this paper, and also look at page 1 to see what is being referred to:

Another reason for system dependency is that in an audio system with balanced signal interfaces between components, ac-related inter-chassis currents do not flow in common with signal return currents (as they do with unbalanced interconnects), and so at least some of the problems that might be helped by balanced power are avoided in the first place.

Onemug -- Thanks very much for the kind comments!

Turboglo -- By "unpredictable" I did not mean that performance would be inconsistent with any given system, I just meant that the effects would vary from system to system in a manner that could not be reliably predicted.

I cannot envision any reason why the Equitech might be contributing to the varying results you are getting. It's just that what it does is apparently not addressing some of the particular anomalies and variations in your electrical supply.

As you've seen in this thread, and no doubt in lots of others, reports of experiences with line conditioners and power regenerators tend to vary widely. I have no particular thoughts to add about them, as I don't use any myself (other than an inexpensive surge suppressor for protection) and I've never sensed the need for one at my location.

Hi Bryan,

No, the reference I linked to, and the comments I made, related to the unpredictability of the benefits (and possible lack of benefits) of converting normal unbalanced 120V AC to balanced 120V AC. So those issues will apply to the Equitech that you are considering.

Hi Bryan,

You didn't miss reading what I was referring to, but my interpretation of it was different. He is saying that what will only occur under a rare combination of circumstances is COMPLETE cancellation of ac-related inter-chassis currents (which can cause high frequency buzz and grunge, and backgrounds which are less "black," in addition to causing low frequency hum). However, SOME improvement may still occur in many cases, to a degree that will vary depending on the relationships between the stray capacitances that are present in each of the interconnected components.

So what I was saying was that since the relationships between those stray capacitances will be essentially random, the degree of reduction of hum, buzz, and grunge provided by a balanced power arrangement will be unpredictable.
