Dekay, after a previous correspondence with you, I did some searching at the PS Audio site about waveforms that are used in their PowerPlants. I just checked to make sure that what I remembered was true. PS Audio states that the perfect waveform for a power supply should be a square wave, BUT (and a big BUT) due to bandwidth limitations and the components of the square wave they should NOT be used in A/V equipment because they "would drive most power transformers crazy". Reading further it sounds like they would have included a square wave in their Multi-Wave units, but compromised with several other waveforms instead. I recommend you check out their site as well. I don't know what the APCs put out, but further investigation sounds like a pretty prudent idea.
APC Line R 1250, Is it Hazardous?
I have heard from a member at this site that the APC Line R 1250 power conditioner/stabilizor, designed for computer use, is also a good unit to use for Hi-fi. I own one of the units myself and use it on our computer. In some or the power conditioning threads there have been warnings that "most" computer power conditioners will damage delicate Hi-fi gear due to them putting out a different type of wave (square wave I believe) and because of these warning I have been afraid to try out the unit on either of our Hi-fi systems. I am also not very technical and would not know what to really ask if I were to contact APC directly. Can any of our technical members familiar with the unit confirm that it is safe to use with Hi-fi gear? If not, then what exactly would I ask APC if I were to contact them? Thanks.
