I have just bought the Edge A2-300 and my experience has been disappointing. I’m getting a constant hum sound from my ATC SCM11 speakers when connected to my Marantz AV Receiver for L & R channel. I thought at first it could be the Marantz, so I connected it to my Audiolab M-Dac and I’m still experiencing the same hum sound from the speakers. I also have the Cambridge Audio CXNv2 which I connected to the Edsge A2-300, this time I got a constant high frequency sound from the speakers. Perhaps the unit is faulty, who knows!!!
I don't have grounding issues as my Roksan Caspian M2 doesn't have any hum sounds or high frequency when theres no signal being passed through. I have good quality interconnects and the Edge is all plugged in the same power supply. I was just wondering if anyone experienced the same problem,
