As the title suggests, I have a question about a true balanced setup.
In order to have a fully balanced setup, at what point does everything in the signal path need to be balanced?
For example. If I buy an Oppo BPD-95 and use the stereo XLR outs, into a true balanced preamp, and then run that out (via the balanced XLR analog outputs) into a dual differential amplifier, then I know 100% that my signal is a true balanced signal through the entire signal path.
For example B, lets say I have the Sony PS3, and run an optical (toslink) cable to an Emotiva XDA-1 fully balanced DAC, and then from the balanced XLR outs into a balanced amp.
Would example B still be considered a true balanced signal path since when it gets converted to analog, it is done with a true balanced DAC?
Example C. Say I buy a Musical Fidelity V-Link, and run a USB cable to the V-Link, then I run the V-Link into the Emotiva XDA-1 (via either toslink or digital coax), and then the XDA-1 balanced out into a fully balanced amplifier.
Would example C (similar to example B, but with a different source of signal origination) be considered a true balanced signal path all the way through?
I guess my question comes down to this: In order to have a true differential balanced signal chain from bits (of information) to amplifier, does the source (if digital) need to be "designed from the ground up" to be considered fully balanced, or does that only matter after the conversion from digital to analog?
I hope what I am asking makes sense. I am really curious about how this works, and what constitutes a 100% true balanced signal for the ENTIRE length of the signal chain.
