While I do think it would help, for a definite increase in output you'd need to effectively double your power. I'd say at least 200W, which means stepping up to the next tier of amp. When you say music, do you mean 2ch music mainly? Yes I think you'd benefit from more power, but if you aren't hearing audible strain now at the levels you listen at, you probably won't benefit as much as you'd like and that's why I say you'd need to move to something more powerful.
