At July 2004, I registered the brand audio-gd ,
September 2004, Kingwa published the first generation diamond difference design at the < Radio & TV> , the best popular audio technology magazine in China . There were a lot DIYer who call me and even wrote me letters to discuss the circuit.
2004 , the fist regular product of audio-gd , XA-100 power amp released. It got good honor from customers and the foundation of Audio-gd was set. Before designing and releasing this this amp, Kingwa had 6 years experience building Diamond Difference circuits .
At 2005, the first regular DAC product DAC-1 released, a TDA1541A with diamond difference output stages.
