Since that would require that you re-wire your headphones, I question how popular might such an amp be. I wonder how many people have built the Gilmore balanced, for example, compared to the standard Gilmore dynamic?
One benefit of a balanced 4-channel setup is double the maximum output voltage swing, which might be useful for very high impedance and inefficient headphones, but I think that's of limited interest to most people.
The other benefit of a balanced 4-ch design is that the output signal return is not dumped into signal ground, but our ground channel also gives the same benefit.
Four channels will also significantly add to the size and cost (not only for the extra amplifier channel, but also increased power supply demand as well as increased PCB real estate). This would be contrary to our goal, which is KISS yet strive for excellent sound quality and performance.
