Joost,
I took a look at your youtube site and listened to your music.
It was tremendous.
I hope lots more people will now listen to your talent for the keyboard and enjoy.

After listening to your sound, I am about to look at the financial possibility of improving my speaker system.
At the moment , as a home hobbyist, I am sure I would even enjoy my own playing with some real speakers like I can see in your videos.
Can you tell us what your setup is, please.?
