Moving beyond the power supply, the schematic reveals the heart of the amplifier’s sonic character: the input and driver stages. The N7000 utilizes a differential input stage, a common but effective topology for reducing noise and distortion. In the schematic, this appears as a pair of matched transistors. This configuration is vital for "Common Mode Rejection," which essentially means that any noise picked up by the cables or internal wiring is canceled out before the signal is amplified. jbl n7000 schematic
