Best AC line conditioning devices?

Thank Ivan. I'm looking into it. I use vibration reduction devices now. Round rubber like balls in pucks. Can't remember names. I was thinking more of AC isolation and conditioning.

There is little info on Alan Maher.

Oops, sorry about that...and my delayed response. Alan Maher Designs on facebook (Alan P Maher), or alanmaherdesigns.net for his official site that is still somewhat under construction, although there's some info there, but you can send him a fb message to ask him any direct questions and/or browse through the fb site to see what he's been up to lately.

Also, forgot to mention that Alan has a facebook testbed group that he likes to keep in the neighborhood of around 300 people or so. As a member I have first crack at buying his newest stuff for at least 50% off retail. These are essentially prototypes and Alan gets the chance to real-world test their effectiveness and compatibility in electrical systems all over the world and let him make adjustments if needed. Whenever there is an improved (or 2.0) version released, we owners of the originals are usually offered an upgrade of the original model to the improved version for moderate fee. This has actually worked very well for me for the last 4 years and I recommend you contact Alan and see if he currently has any room available in the facebook group for you. If not, he may ask you to wait a few months or even a year, but, of course, the prices would be worth it, in my opinion. Just message him, introduce yourself, let him ask you a few questions and ask him about it and see...nothing to lose, really.
