The odd thing is that the other 2 sound modes are dead silent. But when I switch to the Tube mode, I get the buzzing sound.
I will order 2 pairs of the XLR cables and see that will get rid of the buzzing sound.
Another question I have is when you turn off the power of the Freya, I heard a loud thud or boom sound coming from the speakers. I hope my speakers are not damage. Are you suppose to turn off the amplifier first before you turn off the power from the Freya? I thought my speakers last night just blew up. ha ha ha
