An additional explanation.

Most of the time, at home, I'm using headphones with my 4X. But from time to time I ask my wife to 'listen in' on an arrangement. I need an auxiliary sound source that's close to sounding live without taking up a lot of space in our den. This isn't a recording studio.

Even the Tyros 4 sound system(or the similar current Genos system), that I had, had more speakers/cables than I want for my 4X. For home playing that is...
