This is a buyer’s market for this amp at £1,638: that’s comfortably below what 340i X units typically change hands for in the used market, so it reads as a solid buy rather than an ambitious ask. For a clean example, I’d call it strong value, especially if it includes the remote, box, and any fitted DAC/phono modules.
The appeal is straightforward: the 340i X is a seriously capable 100W integrated with real current delivery, a refined but punchy sound, and enough grip for tough speakers. It’s also nicely flexible, with good line-level connectivity and optional onboard DAC/phono paths that keep the setup tidy. At this price, I’d mainly want confirmation of condition, module spec, and that the remote and all original accessories are present.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Moon by Simaudio traces its roots to 1980, when Victor Sima, an Israeli émigré and qualified audio engineer, founded Sima Electronique in Canada with a deliberate mission to craft superior-sounding products at accessible prices. Initially targeting professionals, the brand—later renamed Simaudio—quickly captivated audiophiles for its sonic excellence and value. Sima retired in 1994, selling to Jean Poulin, whose leadership propelled the evolution into the premium MOON series, building on successes like the Celeste line and in-house innovations from their Quebec facilities.
The company specializes in high-performance electronics, excelling in amplifiers, integrated systems, preamplifiers, power amplifiers, and digital converters such as DACs. All products undergo meticulous hand-assembly, in-house chassis machining, and rigorous burn-in testing in Montreal-area factories, emphasizing precision engineering over mass production. While not venturing into speakers, turntables, headphones, or cables, MOON's lineup—from reference-grade flagships to the more approachable "1" series—delivers trickle-down technology for broad appeal.
Positioned firmly in the high-end market, Moon by Simaudio commands respect as a boutique Canadian powerhouse, blending audiophile purity with user-friendly design. Privately held and exported to 45 countries, it rejects esoteric tweaks in favor of natural, detailed sound that invites music lovers to truly immerse themselves, sustaining vibrant success without compromising its heritage of engineering excellence.
