In the history of Head-fi.org, no other product design has held that distinction, further more, the Noble K10 has held its number one position on Head Fi, longer than any other product design in the history of Head-fi.org
There are shows held frequently in the USA, there is a show in Japan near the end of October, and there will probably be a show in Singapore, April of 2017.
