Sure it sounds compressed! It's freaking U-tube! I never hear anything all that good there, maybe it's my settings? And in this case the recording was not PRO quality...I think it might have been from the video camera. I hear lots of distortion too.

I will make my mind up on the sound quality when I hear one hooked to a quality sound system (like nearfield Mackie monitors)

I know when I auditioned the Kurzweil PC3 at Sweetwater Sound, they had a poor speaker (not even stereo) hooked up, then I tried headphones...not much better.
I brought it home, hooked up my Mackies and POW! Outstanding sound. Knocked my socks off.
