Donny, while the KC-110 boasts that it is 30-watts, that is strictly peak power - not RMS. And, it is rated at 15-watts per channel, which is about the same as your keyboard's onboard speakers.

I can't say anything about the Traynor K4, mainly because I don't know anyone that uses one and have never heard it. However, I'm always a bit skeptical about stereo amps that are in a single housing. Just don't make sense to me.

All the best,

Gary cool
