I have an arcam a18 integrated amplifier purchased less than 6 months ago. The unit has worked fine until today: I was listening some hi-resolution flacs played from my pc trough a DAC connected to the arcam. I needed to restart windows and during the process suddenly the display on the arcam showed a "DC Error". Couldn't find on the web any information regarding this problem. Do you guys have any info regarding this? The guys on the music hardware department where I bought it says it needs some kind of reset. This sounds strange to me since cant see any way to do it except opening the unit. Any help would be very appreciated.
