I'm wondering if anyone here has had this problem or can answer this. I know Koiloco and Modulor have attempted to answer or solve the solution, but who knows, maybe someone here knows the problem already.
I've plugged my HE-500 into my Denon AVR-2808CI receiver through speaker taps using a 1/4" to banana plug adapter and for some reason EVERY time I go to use it the right channel is out. The only way to make it come back is to turn up the volume to un-listenable levels and then the right channel begins to slowly fade back in (this seems to apply to when I use speakers as well). It has to do with volume because if I turn down the volume on my ipod (working as a preamp I guess) then the problem isn't solved until it reaches that same un-listenable level of volume. Anyone have any ideas? I've tried different variations of having 1 or 2 grounds plugged in instead and the problem still remains.
You should check your cables with some multimeter and take some measurements (resistance of each line, resistance between the lines - maybe there is some slight short between some of them, who knows)
