VLC uses less resources and can boost the volume up to 200%.
NB: You _NEED_ to have VLC 2.0 (or above) installed and to activate its http interface (read here http://goo.gl/7P0XQ on how to do it). You may need to restart VLC after enabling the web interface.
To test it you can go here http://goo.gl/caqNx after installing the extension.
