Best AC line conditioning devices?

For that, I've been using an Alan Maher Designs Tricell Platform. It's an isolation platform that reduces noise - just put the component on it and plug the platform in. Doesn't draw any wattage from the wall, it only connects to ground. After 3 days it starts to sound really good, but you get the most out of it after 30 days. If you like the sound, try another platform on top of your CDP (on soft feet) and then place another component above on the top platform...you'll be reducing even more noise in your CDP and I think your jaw may drop all over again :)

Alan's web store is not quite ready yet, but you can get the Tricell at Amazon for the time being. One thing I like about Alan is he's up front about his noise spec. He tells you the amount of reduction AND how that curve behaves across the frequency range...(dunno who else is doing that, usually you have to guess). For the Tricell: 65db noise reduction evenly at all points between DC and 10ghz.

Probably not best to rest the platform directly on a flat surface. Some appropriately soft feet underneath should remove the slight midrange "grit" to the sound and your done.

You can also try the platform underneath a power conditioner to really turbocharge its performance.

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.
