Turnip: 'Bad speakers' ? ..... no way! I played it on the same ones I allways use: Mackie SRM450's and Yamaha MSP5's as well.
It's funny you choose for headphones to get a best impression. Headphone amps in keyboards tell not much about the sound quality. (Many have poor quality IMHO)

Do you own a G70? If yes could you send me an own MP3 recording ?
