MOON 250i v2 – High-end analogue stereo integrated amplifier

The MOON 250i v2 by Simaudio is a stereo integrated amplifier designed to deliver MOON’s renowned musicality in a refined, essential and fully analogue configuration. Created for audiophiles seeking exceptional sound quality, operational simplicity and premium construction, the 250i v2 represents one of the most compelling entry points into the Canadian high-end audio world.

The amplifier employs a pure analogue Class A/B circuit design featuring proprietary matched MOON bipolar transistors and an oversized custom toroidal power supply. Its carefully engineered architecture delivers an exceptionally natural, dynamic and engaging musical presentation with extremely low background noise and impressive transparency.

The MOON 250i v2 delivers 50 watts per channel into 8 ohms and 100 watts per channel into 4 ohms, operating in pure Class A for the initial watts to provide excellent tonal fluidity, transient precision and loudspeaker control even at lower listening levels.

Connectivity includes five rear-panel RCA line inputs, an integrated MM phono stage and a front-mounted 3.5 mm mini-jack input for portable devices. A front-panel 6.3 mm headphone output and RCA pre-out are also included for connection to external power amplifiers or active subwoofers.

The rigid anti-resonance chassis has been developed to minimise vibration and external interference, while the optimised internal layout contributes to thermal stability and long-term reliability.

Sonically, the MOON 250i v2 stands out for its natural and highly engaging presentation. Bass response is fast and controlled, the midrange remains open and harmonically rich, while treble reproduction is detailed yet smooth and never aggressive. The soundstage is spacious, focused and realistic, with excellent micro-detail retrieval and musical dynamics.

Entirely designed and manufactured in Canada, the MOON 250i v2 is an ideal solution for listeners seeking a pure analogue integrated amplifier built according to genuine high-end standards.
