M³ can use a simple TLE2426 rail splitter, because the varying return current from the headphones is sourced from or sunk to the power rails through a third amplifier stage. A precise, well-decoupled reference is still needed because the input signal is referenced to ground. In M4, the input signal return current passes through the feedback loop to the complementary input line, and so there is no ground current at all. In fact, M4 essentially has no ground reference. A network of 1M ohm resistors ensure that the floating power supply remains centered relative to the common mode voltage of the input, but that's all. |
