In this post we compare the Koshi Aria chime to the Zaphir Sunray.
When you hear these samples you can experience that the Koshis have a much more bell-like tone and the Zaphir chimes a very crystal clear sound
As you can see the Koshi Aria and the Sunray have similar tunings, some are pitched, some not.
Koshi Aria: A C E A B C E B
Zaphir Sunray: G# B C# E G# E A C# (Summer)
