Yes, I used it with the 2000 and it sounded pretty good. It was the same scenario, a room of 16 X 28 with about a dozen people drinking and singing their hearts out. I ran the keyboard straight into the amp using the mono output, and it had all the punch you needed for a room of that size and larger. I also used it when I was playing some of the smaller senior centers with the PSR-5700 and PSR-740 and it sounded good with them as well. It obviously doesn't have the bottom end of a 15-inch Barbetta Sona 32, but there is sufficient punch to handle most of the small room venues.
