Parasound has amazing Customer Service.
After a google search I was unable to find a schematic for my Parasound DAC. Failing that, this past Saturday, I sent an email to their service department. Within minutes Richard replied that he would look when he got into the office on Monday. I was surprised at the quick response, and on a Saturday at that. Today, Sunday, I received an email from Tony with the schematic attached.
How's that for customer service?
