The Stereo 230 is an integrated amplifier with built-in DAC and phono from Leak, built with comprehensive dual-input connectivity. The Stereo 230 brings Leak's considered engineering to a complete integrated chassis.
Key specs that matter
Two single-ended inputs plus a dedicated phono input are provided. Input sensitivity is 480mV for line-level or 4.1mV for phono MM. Input impedance is 10k ohms single-ended. Phono MM/MC current-sensing input impedance is the standard 47,000 ohms. Output power is 75W into 8 ohms, rising to 115W into 4 ohms. Frequency response spans 20Hz to 20,000Hz within plus-or-minus 3dB. Signal-to-noise ratio exceeds 109dB, with total harmonic distortion plus noise at 0.003%. At 325 x 145 x 426mm and 12.7kg, the Stereo 230 represents an accessible integrated amplifier commitment.
Sound and use context
Expect clean amplification reflecting the strong over-109dB signal-to-noise figure, combined with convenient built-in DAC and phono functionality within one integrated chassis, consistent with Leak's broader revived British engineering heritage.
Pairing
The built-in DAC and phono input cover digital and vinyl sources directly without needing separate outboard components.
Alternatives
Leak's own broader loudspeaker catalogue, including the Sandwich series, offers natural companion speakers for a coherently voiced, entirely Leak-based system.
