IMO, its a matter of taste. Having played on the xp60 for a while before playing the 740, i did feel the 740 sounds were toyish in the beginning. However, as i played it more and more I started to like the difference they offered. They didn't seem toyish any more. In fact there are some sounds I love on the 740 as compared to the xp60. I think its a matter of perception.
