Are you using the same Power cord for both units? I recently had a Pre Amp that flickered and apparently died, and when I tried a back up Pre amp it had a loud hum. Changing the Power Cord fixed both units
DAC Repair
I have an Arcam rDac as well as a Cambridge DacMagic. Both experiencing basically the same issue, not powering on. Mostly concerned with a repair to the Arcam. Both are small and easy to ship so looking for a reliable tech in the US to send for repair. I am located in Scottsdale, AZ.
Thanks
