Droplet CD Player: Contacting Consonance

I purchased a dealer demo Droplet CDP5.0 one year ago that recently broke down. Changing the fuses did not help and I suspect a problem either in the power supply or the power module. According to a friend, the unit is getting enough power to energize the relay but not keep it latched. Since there is no US distributor, I have been writing to Opera-Consonance in Beijing. The company has not responded once. I am using the website email address: operaamp AT vip.163.com. Is this the right address? Has anyone successfully contacted this company recently? Thanks for any advice.
