I have had my PXS1000 about 1 1/2 years. I am an older guy that played guitar mostly and decided to take up piano in my old age. Admittedly I am just going on to book 2 so I’m by no means even close to an expert. One thing I DO know, is that I agree 100% with Sslyusov! I live in an apartment and mostly use a Sony headset. When not wearing the headset the mechanical noise is terrible! As a matter of fact, my keyboard volume is pathetic! It would have to have an amp attached if played out somewhere.
