MOON 340i X – High-end audiophile integrated amplifier

The MOON 340i X by Simaudio is a high-end integrated amplifier engineered to deliver refined musicality, substantial power output and exceptional loudspeaker control within an elegant and compact audiophile component.

Built upon more than three decades of Simaudio high-end engineering expertise, the MOON 340i X combines a sophisticated dual-mono architecture, oversized custom toroidal transformer power supply and proprietary matched MOON bipolar output transistors designed for exceptional speed, linearity and authority.

The 340i X delivers 100 watts per channel into 8 ohms and 200 watts per channel into 4 ohms, operating in pure Class A for the first 5 watts to maximise fluidity, natural tonal balance and exceptional microdynamic performance even at lower listening levels.

Its fully analogue signal path ensures an extremely short and clean audio circuit, while MOON’s proprietary volume control system guarantees precise adjustment and perfect channel balance. Anti-resonance mechanical construction and carefully optimised internal layout help maintain ultra-low background noise and exceptional sonic transparency.

The MOON 340i X also offers impressive modular flexibility thanks to optional D3 high-resolution DAC and PX MM/MC phono modules, transforming the amplifier into a complete solution for modern high-end audio systems.

Connectivity includes line-level RCA inputs, balanced XLR input, front-panel headphone output, variable pre-out and fixed line-out, making the 340i X extremely versatile both in traditional stereo systems and more advanced setups with external power amplifiers or active subwoofers.

During listening sessions, the MOON 340i X stands out for its deep controlled bass, rich natural midrange and refined yet highly detailed treble response. The soundstage is expansive, stable and holographic, delivering excellent micro-detail retrieval and musical involvement even with demanding loudspeakers.

Entirely manufactured in Canada to extremely high standards, the MOON 340i X represents one of the most balanced and musically engaging integrated amplifiers available in today’s hi-fi and high-end audio market.
