The PSR-SX900 incorporates a newly-designed, bi-amped speaker system with a wide stereo audio field. To ensure silky-smooth, high-quality sound, the DAC (Digital Audio Converter) on this keyboard has been upgraded to 32-bit, the same as those found in Genos and in the top-of-the-line Yamaha MONTAGE synthesizer.

Just the above two improvements will guarantee that the sound quality will be better than the previous PSR's.

I can't wait to try it!
