Hi to all,
I had the same concern about plugging amps into the wall. I decided to write to Andy at Synergistic Research and this was my response.
Almost all power conditioners limit current, which is why you hear recommendations to plug the amps directly into the wall. However, All Synergistic power conditioners are completely non-current limiting. In fact, the cells have slight capacitance, so they can provide more current on demand than the wall itself. So, not only can you plug the amps into the PowerCell 12, you SHOULD. Amps can benefit from conditioned power just as much as any other component when the conditioner can provide enough current.
