I'm going with Ian on this one, I don't like dry sound - it's just not natural. When you're performing with a band in a large hall, the sound bounces around like a ping-pong ball, thus the walls, ceiling, floors windows, naturally all produce some reverb, echo and delay. So why would you want your arranger keyboard to sound as if you were in a soundproof room - it would not be natural at all. Even when performing outdoors, there is some echo, reverberation and delay, sound bouncing from objects near and far.
