Audio Alchemy repair

I have a DTI Pro and DDE v3.0 that are in need of repair/service. I contacted CIA Audio, and Dusty no longer services these units. Does anyone know where I can send these units? Thanks in advance
I also have a DDE v3.0 that is in need of repair. The analog output section does not work but everything else does. Any leads on parts or a repair person would be much appreciated. Thanks JD
