Any type of power conditioner or treatment can make an amp sound "slower" by limiting the amount of current available to the device as it is needed. In order to avoid this, select a device that is capable of providing at least 30% - 60% more power at any given time than what the device would draw under full load. As such, if you had an amp that is capable of drawing 8 amps continuous, you would want a device that could supply at least 12 - 15 amps continuous. Since ratings from manufacturers are "fudged" so many times, the more headroom that you can provide in terms of current capacity on the "filtering device", the less likely it is to impact the "apparent speed" of the device connected to it. Too many people try to draw too hard on a steady state basis from various filters or transformers and the distortion that they produce in such cases is passed on into the audio system. By keeping the load on the transformer or filter well below capacity at any given time, those distortions and current limiting are removed from the picture or at least drastically reduced. Sean
