Hum in the system
Hi, I just installed a MSB Link DAC III in my system and that promptly caused a low but audible hum. The hum goes away as soon as I turn off my power amp. (but that's not exactly a workable solution....) Now, both the power amp (Acurus A-100) and the MSB have 3-pronged plugs, so I wonder if there is a ground loop problem. My question is, how do I fix it? The Mondial M.A.G.I.C won't work, because it is a cable ground isolator - at any rate I don't have cable TV. Any suggestions/solutions will be much appreciated. Thanks!
