As has been indicated in the prior posts, using an adaptor to connect your system through the balanced inputs has no advantage and may actually be disadvantageous. For one, using the balanced inputs does not mean that the signal would be balanced since an adaptor will not convert your standard signal to a balanced one. You seem to be thinking that the adaptor will provide you with a shortcut to having a balanced system. It will not. Secondly, the fewer connections, the better. Adding yet another interface between the signal and your amplifier or preamp will more than likely increase noise, to say nothing
