Is there anyone that can give a full description of the Airbow SC21? It would be helpful if there could be a comparison to the Stax SR507. I've read that the SC21 rivals the Stax 009 but I'm very skeptical of this claim. Its very rare to get even a small amount of information about the Airbow except some blurb in Japanese from the manufacturer. If this post belongs in the Stax forums, let me know.
