Glenn,

Two speakers could be used as monitors, but in my case with the PSR-3000 I used the keyboard speakers as monitors.

As for how it compares with the Z-2200 system, it's a significant improvement in both sould quality and overall power.

Semilive,

The article is right on the money. In fact, when I cranked it up to a boost level of 6 it was more than I could handle, but amazingly, it all of the sounds were still quite clear and crisp.

Chico,

You're going to love this system.

BTW: The hook-up I used was not complicated at all. I merely used the single, stereo input and did not worry about the 5.1 surround sound option. Unless you have the option of placing speakers at each corner of the room you're performing at, it really doesn't matter. I hope placing the satellites on stands accomplishes what I believe it will, which is to have a wide dispersement of sounds throughout the rooms where I perform regularly.
