Sugar1, what a Lightspeed will do is give what your source (cdp, dac, etc) is giving out without anything added or subtracted, in other words it's like feeding your source directly into your poweramp, yet with control over the volume. It's like an open window to the rest of the system.
Most owners say it is more 3d, and extendeds the frequency at both ends (highs and lows) that is because it is direct coupled (good for the bass. And it's top end is almost to infinity (good for the highs) which become delicate and extended.
It is not for you if you if you want to add colourations to fix problems elswhere in the system.
