First off, sorry for such a noob question! The story goes as follows: a friend of mine, who is a very good electronic technician, worked on a balanced amplifier for his HiFiMAN RE-ZERO, and I asked him if he could make one for me too for my HiFiMAN RE-272. The question is: is it strictly necessary that the source has a balanced out too in order to all the "balanced-magic" to happen? My source would be a Cowon J3.
Thanks in advance for your replies guys!
