Oppo 205 revelations, questions..
 @allanblissett  It seems to me the ifi addresses ac noise. I don’t understand your reference to the optical input?? 
Oppo 205 revelations, questions..
I@allanblissett. The ifi sounds interesting. I’d like to hear your experience. My experience is that no single isolation/conditioning unit does what I achieve using a combination of balanced power for common mode noise and other units for differen...
