Actually, while it is the same chipset, isn't the implementation slightly different? As in, you're going through more OPA1622's when you listen to the SE out (as with FiiO's diagram on their website). Please correct me if I'm wrong in any way, I'm no electrical engineer.![]()
I have to say that I'm in the camp that does hear a difference with the AM3. While the difference between the SE and balanced isn't nearly as big as I've heard with other amps, I still could hear one (although somewhat subtle) after volume-matching. Though I do acknowledge that it could be my brain just wanting to hear that.
With HD 650, theAM3 difference between SE and balanced is stunning. Double power and increased grab on the drivers might be the explanation.
I'm looking for a balanced cable for my HD-650, right now. I'm not sure if I want to go for the Moon Audio or something for a little less money.
