Who has dumped the power conditioner?

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.

Follow up:

I just wanted to update my situation. After consulting with some trusted experts, I decided to try replacing the stock power cord that came with the Equitech. It was suggested that the small copper conductors in the beldon pc were resonating with more voltage draw. I was pointed toward something with a solid core, so I ordered a JPS Labs Power AC+. This has totally fixed the problem and further opened up the soundstage. It's kind of annoying that I'd have to spend an additional $400 for an expensive power conditioner to be listenable. But, oh well. I'm thrilled with the way things are sounding.

Al, I am considering a couple of power isolation transformer based products. One takes non balanced in and outputs balanced power, or so I believe. That's the equi=tech. The other is a Torus power isolation unit and since I don't have balanced AC in the house and won't be adding in via dedicated lines, I won't get the balanced in version, just the non balanced in.

Would you say that the equi=tech would not really be impacted by the balanced power issues you mentioned because it is not actually connected to 240V balanced in power?

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.

Al, I had a look at the paper and it looks to me that the author believes that balanced AC power will only reduce hum under a specific and rare condition -- in a system with three chassis that have the same capacitance. But most of the article content regarding "balanced vrs unbalanced" pertains to interconnects and signal, not power. I don't really see much here that is related to balanced power causing inconsistencies in results in different systems. Unless I just missed it.
