Scott, I was not aware you replied to my post and I thank you. To answer, I am using the internal speakers but at my gig, using the exact same amp and speakers I used with my Casio 330. Hope you're still there to reply. Thanks again.
Just purchased Privia 560, previously used Privia 330. Why dies the middle register sound tinny compared to my Privia 330, very frustrating? Also, notes b through e, octave below middle C, sound resonates/vibrates the chassis. Again, this doesn’t occur on the 330.
