My Grados, when plugged into my RA-1, when the power is on and no music is playing, there is a slight hissing, like electronic or something. My HPA-1 does it too, but i wouldn´t expect this from something that uses batteries as the power source...??? BTW, it does not get worse as you turn the volume up at all... it´s the same no matter what, i´m just wondering if this is normal. Thanks!
