I've used the KC-500, Hartke 200 watt Keyboard amp, fender Kx-100 as well as PA systems (Mackie 808s w/crest speakers, Yorkville keyboard amps as well as PA speakers, Behringer, Alesis, etc.). I would trade them all for my Bose L1's. I have two of them, 90% of the time I'm using only 1. They are without a doubt the best I have used for sound, portability, reliability and convenience. I use them for keyboards (including my px5s of course), vocals and horns simultaneously, and they carry the load extremely efficiently. I have used them for large halls and outdoor gigs, never had a problem getting the sound out without distortion. You don't need monitors with them, you put one behind or to the side of you, and you hear everything clearly without feedback in most cases. Factor that savings into the price. I highly recommend them, wouldn't play through anything else these days. Good luck, whatever you choose.

I have both the Krome 88 and the Casio PX5s. The Casio is much better, IMHO, for live performance...The Korg doesn't do well when tweaking on the fly, since you have to go through menus and make adjustments with a sometimes finicky Touch Screen. As far as sounds, I'll take the Casio for pianos, basses, saxes guitars and drums...I'll take the korg for Organs, Brass, and winds in general. Action is no contest... Casio all the way. I just purchased a second PX5S, for a backup...I think that tells you where I'm coming from. Good luck! crem
