Innersound ESL XA200 Active Crossover / Power Amp?

Do you have two separate units? The x-over is one piece and the amp is another. Check out sanders sound, full description is available.

The two separate pieces are the newer vision using a digital crossover, and an amplifier. Before the digital crossover, he was using an electronic crossover which was combined in the same chasis as the amp. I think this is what the OP has. I'm not sure what the value of it is, to anyone who isn't using Sanders, or Innersound electrostats.
