A balanced amplifier will still be referenced to ground.
How does the balanced DAC reject noise?
The DAC has a balanced output, goes thru a balanced cable and is accepted by a balanced input in the amplifier.
So the noise is rejected in the amplifiers input stage, assuming the noise is COMMON to both the Non-inverting and Inverting signals.
By the way, you need to REjECT noise to get rid of it.
some of these so called "balanced" topologies seem to do nothing to reject noise, they just continue to amplify it in a "balanced" configuration.
If an amplifier has a balanced input, then Common Mode noise is rejected and we are left with the noise the amplifier circuit itself generates.
Whether the amplifier is Single ended or Balanced amplification, there will still be noise generated within the amplifier circuit.
