Whatver PurePower dose or dose not does but it works 100% perfect to address problem with dimmers.

Canuck,

I would like to amend this somehow: my experience is not similar to Romy's. I have always observed that dimmer switches (among other devices) are not 100% filtered by PP2000. Even after my unit was returned and inspected by APS, supposedly with no problem at all in the unit, I can still hear when devices are turned on/off. Now I know Romy would insist that my PP unit is not operating properly, and he may well be right. Another factor to take into account is that he has a US (120V) unit while mine is EU (240V). And yet another is that Romy's units may have been modified by APS specifically to suit his needs/complaints and may have little to do with standard factory units. Finally, Romy has a dedicated ground plane for audio that is different from his PP's, while at the moment the ground for my audio gear is that provided by the PP, which means it includes the noise fed back by the PP (and we know this is not to be taken lightly) and god knows what else (dimmers?). I plan to have a dedicated ground in my future house but for now I must deal with what I have.

As a result I would urge you to be cautious with the ability of PP to shield you from dimmer noise completely. That said, the PP has other very strong points that I would not part with.

Cheers
