I've read a lot posts about the Yamaha S970 as being a insufficient workstation. What people don't know is this keyboard that i own, actually sounds like a CD when playing music. The sounds of any keyboard is dependent on the sound system its going thru. This keyboard has a function where you can tweak the sounds to your liking and save it. Everytime I play this keyboard at a function, people, after seeing me playing , remark that they thought it was a CD or soundtrack playing through the house speakers. What you hear online and in stores is NOT the only choice of sound you're left with. Whether or not you're a fan of Yamaha keyboards , the Yamaha S970 is an amazing instrument. The USB audio player by itself is worth the money.
