Here is the thing : Balanced is much more powerfull and much more silent... Well, at least, that is what Schiit says.I feel like there’s a slight difference from the SE compared to the balanced connection.
But, balanced connexion is also much more isolated (can I say it like this in english ??). For exemple, when I am connected throw jack output, I have some wierd noices coming randomly from time to time. I thought it was a problem with the MJ2, but I also have the problem with my Myryad preamp (much more audible with the MJ2 so). So I have a problem with my power... Don't know where it comes from, but I have it. Anyways, that problem occures only when using SE output. It never happen with the XLR output.
