ZL120 vs Concert Fidelity ZL-120V2SE
The ZL-120V2SE's input impedance is 47Ω against the ZL120's 20Ω. Both share power @ 8ω (120W), input sensitivity (2.0V RMS), and width (450 mm).
Both turn up in the same documented systems.

About the ZL120
The Silicon Arts Design ZL120 is a high-end solid-state monoblock power amplifier, later associated with the Concert Fidelity brand. Its bridged (BTL) circuit uses an input buffer, a phase-inverting gain stage, a Class-A driver stage, and a push-pull MOSFET output stage with two parallel MOSFET pairs. It employs local feedback only, with no global negative feedback. The original ZL-120 documentation specifies selectable 20 kOhm or 100 kOhm input impedance; later ZL-120V2SE information describes an updated model with 47 kOhm input impedance, higher-current transformers, and 50% greater power-supply capacitance. The data below primarily identifies the original Silicon Arts Design ZL120, while clearly noting later-version data where applicable.
