I did not hear a nearly £1000 price difference in terms of sound quality 🤓. The Yamaha sounded brighter in almost every sound category from the piano to the brass . that the use

I don’t know if it’s deliberate by Yamaha but I prefer the softer warmer sounds of the Korg .

In alive setting I would bet it would be very difficult to tell the difference between sound quality of these instruments .

I am biased however as I use all the Creative and sonic features of my instrument and therefore I would feel restricted on the Yamaha.
