Hi Mejames, there is really no such thing as a "truly balanced" output from a digital player. There is only one signal per channel stored on the disc, so every player that has a balanced output has to create the inverted signal to achieve a balanced output.
Some players do this in the digital domain and then have separate dacs for the inverted and non inverted signals. Some do it in the analog domain using op-amps or some other analog inverter.
I also agree with Unsound and question the statement in the original post that balanced is the ultimate goal. The ultimate goal is good sound. I don't think balanced operation is a prerequisite to get it.
