I've always dealt directly with Aodyo in France (from the U.S.), and it has been a good and smooth experience.
The Sylphyo works for most folks directly out of the box, but as you play more and more you'll find that there are a lot of things you can alter to suit your particular style of playing. People come to this instrument from all backgrounds, and the settings you can control on the instrument I believe cover a wide range of playing styles.
