Perfect Path Technologies - "Stop It" AC Duplex passive line conditioners


I've been using some of PPT's latest passive line conditioning devices for a few months now. Grouped under the "Stop It!" monicker, the current range consists of AC Duplex plugs and RCA plugs. This will soon be expanded to include UK AC and Schuko (international AC) varieties. I'm very favourably impressed with the improvements in my system, and with the value for money they offer.

My first Stop It AC Duplex samples arrived unexpectedly 3 or 4 months ago, together with a bundle of PPT products I purchased. It's not unusual for pleasant surprises to happen spontaneously when you invest in a PPT bundle! I unwrapped and examined the offering - a pack containing 10 small plastic AC infant safety stoppers, with some very unusual visual characteristics. They are treated with a silvery gray hybrid mixture, which appears to contain pearly particles of some kind. I have no idea what's in the mixture, but it looks pretty. Although the pack was an early production run and came without instructions, it didn't take me long to figure out how to use them. The two protruding prongs really gave the game away, so I fired up the sound system and plugged just one Stop It Duplex into the wall. I have to admit that the small size of the plug and the relatively thin coating had me expecting a very minor effect, compared to a PPT mat for example. But not really - the effect was...

BIG and obvious from the first track. Not the same as a mat, which lifts the entire soundstage, the Duplex plug exposed top end detail and enhanced specific imaging, which I found immediately exhilarating and exciting. I should never have doubted Tim to come up with something special and surprising. So in went the 9 remaining plugs, into all remaining empty AC wall outlets in the room, and into the empty outlets on the back of my SR PowerCell 12 UEF. This magnified the effect as you would expect, and I began to notice the same kind of lift you get with the PPT mats, as well as further enhanced top end sparkle, and a laser-like exposure of inner detail which contributed to enhanced image specificity. All the plugs were used in my listening room, and I was very happy with the result.

After a quick email to Tim to thank him for the bonus gift and to offer my unqualified approval and praise, the reply came back indicating that further improvements could be expected by treating every unused AC wall outlet, with Stop It Duplex plugs. So I placed an order (at full price) for 20 more Stop It plugs to treat the entire house. By this time I knew they were going to work. But how great an effect, when the outlets to be treated are nowhere near the sound system, not even on the same floor?

It has taken me a while to come to a conclusion about this. In my experience, I found that in general, the closer the plug is located to the sound system, the more instantaneous the positive effect. However, the plugs placed in remote locations around the house, over a period of a few weeks, eventually intensify to contribute a similar additional AC cleansing power. It's initially more subtle and it takes longer to activate, but it's definitely worth treating every unused outlet in the house.

Dirty AC power is obviously a problem, we all know that. So should you "Stop It" with PPT duplex plugs? It's a great product that works as advertised, it's reasonably priced and can be purchased individually as the budget permits. If your results match mine, you'll hear a worthwhile improvement with each treated outlet, regardless of its location in the house. So I say Go For It!

Not sure. FWIW I would never tell anyone to not try them in the breaker box, but don’t be surprised if something doesn’t sound right over time. Maybe too much HF detail is what I am experiencing? Anyway always experiment and give it time..I will say the emats under my components always made them sound better, so I am thankful for that.

Yes I am using HFC interconnects and Hemisphere Conditioner. I believe they play fine together in my experience. What I didn’t like was the MC-05’s with the Emats. But just to clarify, 2 other Audiogon Members here that I know, have experienced the brightness or excessive detail with emats installed in the circuit breaker panel. If they want to come forward to validate, it’s up to them. BTW none of them own any HFC products. Don’t really want to make a big deal about it. I think everyone should try at least 1 emat because of the risk-free trial period.
I would like to add ..I have tried the Contact Paste and the Emats (under components). I think both of these products make a noticeable improvement in my system.

What seems to be a high recommendation is the Emats placed inside Circuit Breaker boxes. I have found it to have a negative influence to my system. Its makes things brighter and fatiguing.

Initially I liked what the emats did in the breaker box, but over time my system got very fatiguing. They were in the breaker box for weeks. I tried reinstalling them a few times and was not happy.

FWIW I am not the only one that has experienced this issue, I know of 2 other people that have the same view as me. So not all perfect :) I still like the product though. just giving you all my honest opinion.
