I am actually an advocate for keeping things simple, as I suspect you are.
Where a transformer really works well is if you have a single-ended preamp, but have to run the cable a good long distance, something you can't do single-ended. Then a set of transformers at either end of the cable will be less colored than a single-ended cable of the same length with no transformers.
However, we don't use transformers in our gear and so can have a benefit even with very short runs. We've all heard differences between RCA-based cables and have often favored one over the other; often paid more for it. What if you could have the best cable made cost-no-object, but didn't have to pay the cost? That is what balanced line really offers.
Follow Ups:
DH Labs make shielded, directional, 'balanced' cables with RCA connectors, where (if I understand it right) the shielding is only attached to one end of the cable, and not the other, so that theoretically, you avoid ground loops because the shield is not in the circuit with the 'return' leg.
Is there a real benefit to this approach?
The advantage is that there is no signal current through the shield- the signal and ground get treated the same way, and the shield is merely shield.
Its not a perfect arrangement, but I would expect it to work a little better. We used to make interconnects in this manner many years ago back in the 1980s.
