Canadian manufacturer of toroidial isolation transformers. Torus Power started out as a side venture for Plitron, one of the foremost magnetics manufacturers in the world. They've applied their know-how to design the best power conditioners on the market. Install one of these in your system and you'll notice an increase in bass dynamics and lower noise floor, thanks to increased ability to deliver current relative to the wall outlet and the reduction in electrical noise from the filtration effects of the isolation transformer. A much better idea than a power regenerator, because the core of these devices is passive, with high current headroom, as opposed to a hard clipping and failure prone power amplifier.
