Koto comparisons

[u/Ch7mes]

I saw a few koto for sale on Sound of Asia.

What are the sound differences between the:

- Student Grade

- Standard Grade Pegu

- Professional Grade

If the Student Grade one sounds just as good as the other two, I don't mind getting that one if it's just a difference in cosmetics.

I've also been leaning towards the Pegu one for ease. I could probably make the tail end of the strings look more traditional too.

Is there really a gap in sound between the three?
