I have one; I use it occasionally on outdoor speakers. I am not so big a fan of modding SS equipment anymore. The few experiments I tried were really so-so results. Sometimes the sound gets worse. I am a fan of Brian GT's GC kits. The sound they provide for the money is the best I have heard within reason for SS equipment. And you can use whatever parts you like. Using two kits to bi-amp a nice horn-loaded two way is my next dream. Whats up with you?
