Can anyone recommend a surge suppresor/line conditoner. The problem i have is my refrigerator is causing interference through my tv and speakers. I was looking at the Adcom Ace 515 but i saw some bad reviews on the net. I also have been looking at the Panamax 1000. I would like to keep the price around 200 or so. The current protection i have is a piece of junk Monster with clean power stage 1. My receiver is a Sony Str-da4es. I hope someone has had the same problem. Thanks!

Make sure you can return the product if it does not solve your problem.
In the links and info thread there is a link to a lengthy discussion about this stuff.

That thread did me no good. You guys are just bickering about the same thing. Can anyone recommend a line conditioner to get rid of appliance noise like my refrigerator! Thank You.

Try powering the refrigerator through your monster or another surge protector/EMI filter. If you know it's the fridge then the closer you block the noise at the source the better. Make sure the appliance is on a grounded outlet. Go buy a cheap neon indicator outlet tester.

"Go buy a cheap neon indicator outlet tester". I am not sure what you mean by that-not familar. The fridge is grounded. Are you saying to buy a cheap EMI and plug that in to it then to the wall? Will that work?

Hardware stores, Home Depot, etc. usually have a three-prong outlet tester. It checks for miswired phase/neutral or missing ground. Just because an outlet is a three-prong doesn't mean it got wired right. I'd try the cheapest fixes first, like plug the refrigerator into a surge protector. Best if it had an internal EMI filter. If this is a conducted noise problem (vs. radiated) then maybe you can attenuate it closer to the appliance. Strange a refrigerator is generating interference. Is it old or a newer one with fancy electronic controls?

I checked, Home Depot has a GFCI tester for about $8. Good tool to have around, plus checks your GFCIs. You can plug a refrigerator into a surge protector. Just make sure it can handle the appliance amp rating. These filters are not sophisticated and will usually attenuate noise both ways - from the line or from the load. But there's only so much you can do down on the end of the cord though. Once interference gets out onto the cord it can be difficult to block. All depends on the frequency. You can buy some cheap ferrite cores to put on the line cords too. They might help some but no assurances.

We are debating the merits of AC conditioners versus AC synthesizers.

That is impossible. Your results could easily vary. That is why I suggested that what ever you do make sure you can return the product if it does not work. The purpose of the thread was to educate you as to why that would happen.

Anyone who calls power conditioners a racket is largely justified.
I just returned a new Panamax that was connected to my new Pioneer PRO-530HD RPTV.The line conditioner magnified the signal(its bad parts) rather than cleaning it up or conditioning it.I also now considering a Monster unit.
It didn't help the moire but it DID improve the clarity of the picture. So, yes it worked. Not only could I see an improvement, but my wife could it as well.
I'm an EMC engineer. I work with this stuff as a living. Most claims on this are pure hype.
In this example, the conditioner might have actually done something by making things worse.
Nearly all the comments are correct when related to line conditioners and there is much vodoo involved.
...It is a 120V AC generator or more accurately an AC synthesizer with its own power supply and signal generator that puts out pure clean power for your equipment. It is not a joke, snake oil or a way to seperate you from your money.
Power conditioners and balanced transformers used to be the only way to attempt to clean up your power lines.
They range from simple filters to complex ones, to isolation transformers, to even passing electricity through rare earth materials, past magnets, and so on.
Most people who have tried them have reported mixed results. They do some good, but they seem to add as many problems as they fix.
The truth is that these devices do not and cannot address the real and significant problems which are noise in the audio spectrum, regulating the AC voltage, and repairing damage to the symmetry of the AC wave form.
3. A couple of conditioners were tested and also created. All had some of the attributes of the AC synthesizer but none could give all the results nor to the same level. Conditioners do not get rid of problems they move them somewhere else and reduce some of the negative effects. This was shown by negligible differences using the distortion analyzer. I must also add that an old Mitsubishi VCR using an AC transformer was simply plugged into the same circuit as the audio system and ended up doing some of the same things as the conditioners.

That is the gist of the thread as related to your question. The point is try a line conditioner for your problem. If you want to get serious then an AC synthesizer is recommended for all of the above reasons.
I am sorry that it may have been too complex or lengthy. It is a thread that I take great pride in because of EMC Guy. This poster pushed the thread and my knowledge to the limits and in the end we have one of the most complete discussions on this topic covering every angle of AC power. It is awesome!

Richard, I didn't realize I made such a lasting impression! Well I'll be back now and then to either further push your knowledge to the limits, or at least to annoy you a little...

Knowledge is only annoying if you are stubborn. I too appreciate the educated feedback, from all the members on the forum who can give expert advice from outside my own experience. That's the whole point of having this type of forum: deeper discussion and understanding of a topic when most other groups would've become bored.
