Hello, I´m a long time reader but this is the first thread I start. I apologize beforehand for my writing/spelling, english isn´t my native language. My setup is: Macbook pro---Burson HA-160DS----Sennheiser HD650 or AKG Q701.
My HA-160DS arrived yesterday, bought it directly from burson, my previous amp/dac was a fiio e7/e9. The problem is I´m hearing a hum (low noise) with my 650s, the hum starts when I turn on the burson, it doesn´t matter if the source is connected or not, also the noise remains the same with the volume knob all the way down or up.
The hum is barely audible but it´s driving me insane, when I´m using the AKG´s I can hear it but it isn´t as bothersome (almost inaudible). Is there any Burson owner that has experienced this problem?
