Youtube Video Summary
Premium build with a large, Monarch-like shell that sits extremely comfortably, accented by subtle blue flecks and a secure nozzle lip. The bundled 4.4mm cable feels upscale, while the case and tips are serviceable. There’s noted pricing controversy—an initial teaser around $1,000 for a handful of units before settling near $1,600—but the product itself presents as a polished, high-value package.
Sonically, this is a strong, impactful bass tuning with rich warmth that never smothers the mids. Female vocals pop, instrumentals sound lifelike, and earlier worries about a dark treble prove overstated; the tonal balance feels right and cohesive. Sub-bass digs deep, mid-bass hits with authority, and the overall presentation is sweet, engaging, and musical—the sort of set that invites long sessions without fatigue. It comes across as a top-tier collaboration with a crowd-pleasing signature for bass lovers who still care about clarity and timbre.
In comparisons, Dunu’s Mirai reads brighter and leaner with issues like hiss and channel imbalance on the sample heard, scoring around “three stars,” while Jupiter earns a decisive “five-star” nod. Against heavy hitters like Elysian Annihilator and Grand Maestro, those sets feel more resolute, but Jupiter is more fun, with a richer, sweeter tonality. Versus Fatfreq Scarlet Mini, Jupiter offers just-right bass (rolling off warmth around ~200 Hz) rather than excess. The conclusion is emphatic: a 9.04/10, described as a “love letter” to bassheads and one of the finest pure basshead tunings heard—highly recommended, especially if a second-hand deal brings the price closer to earth.
