Angelo: I definitely can say I get PLENTY of robust volume plugging the SxA100's directly into the Yamaha PSR2000 when BOTH the SxA100 & PSR2000's volume level knobs are set at somewhere between the 1:00 & 2:00 position.

I'm curious to know why Deatonent somehow needs to max out the volume levels of both the SxA100 & his keyboard (X1) to get enough volume output for even a dinner music setting. Is this the result of his keyboard or his SxA100's?

With my EV PA/keyboard system, I only need to take along an external mixer for large wedding banquet room gigs so I'm HOPING now, that plugging the SxA100's into the XD9 or Tyros will produce the same similar 'sound volume' results I'm currently getting with the PSR2000. Can anyone tell me what I should expect?
