I can't imagine why even a base model LS100 isn't sounding better than the 99. Amp, wire, something. My feeling is the Rogue equipment is ok, but Modwright and Musical Design are both making far more detailed preamps for the same money or less. As I just posted here:

even my basic Musical Design SP2-B smoked my buddy's 99 Magnum. In particular, a far more 3-d sound stage and more natural vocals (mids).
