This looks ambitious, not a fair ask: £3,199 sits well above the 75th percentile of your recent GBP comparables at £2,511, and far above the £1,823 median. For a used 404, that’s premium pricing unless the example is especially strong and nicely optioned.
The upside is that the 404 is a very well-regarded, musical integrated with proper drive, refinement, and a slightly tactile, “alive” presentation that many listeners love. If this one is boxed, mint, and includes useful extras like the phono stage or DAC module, it becomes more defensible—but at this level, buyers should expect standout condition and specification rather than just a clean used unit.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Moonriver Audio, a Swedish high-end audio brand based in Malmö, draws its name from the iconic song "Moon River" featured in the 1961 film Breakfast at Tiffany's. Founded in recent years by chief engineer George Polychronidis, the company embodies a fusion of vintage aesthetics and contemporary engineering, with products meticulously designed and hand-assembled in Sweden. This heritage reflects a passion for timeless audio reproduction, evoking the warmth of classic designs while leveraging modern precision.
The brand specializes in integrated amplifiers, exemplified by its flagship Model 404 and the refined 404 Reference. These transistor-based powerhouses deliver tube-like warmth, exceptional dynamics, and tonal accuracy, prioritizing through-hole components for reliability and purity. Moonriver focuses squarely on amplification, eschewing diversification into speakers, turntables, DACs, headphones, or cables to hone its expertise in this core category.
Positioned as an exciting newcomer in the high-end market, Moonriver garners acclaim for its balanced, detailed sound that rivals established names. Hand-built quality and a user-oriented philosophy appeal to discerning hi-fi enthusiasts seeking mid-to-high-end performers with a boutique Swedish flair, blending accessibility with audiophile refinement.
