Unique Melody Maven II ‘Crescent’ ($1,799, reviewed here). Comparing the Grand Oriveti Supremacy and the Unique Melody Maven II is like watching a play unfold from two very different seats. Supremacy is the cozy, front-row experience – intimate and weighty. Maven II? That’s the VIP balcony: grander, broader, but not quite as in your face. Let’s break down their differences, track by track.
Starting with Madi Diaz’s Same Risk, Supremacy adds warmth to the intro drums, bringing a snug, intimate feel with its slight mid-bass bloom. Vocals come through cleanly and forward, though a touch dry from upper treble air.
Supremacy’s stage is contained, adding just enough depth without spreading things out too wide. Maven II takes a different approach here, tightening up the bass and toning down the mid-bass bloom for a leaner, more precise punch. The Maven II also brings a much grander stage, with vocals sitting further back but still rich and refined, creating a spacious, more delicate feel.

On to Ilan Bluestone’s I Believe, Maven II really stretches its legs. Bass hits are quick, punchy, and decay fast enough to match the track’s energy. Its stage feels expansive with pinpoint imaging and lots of air between elements.
Supremacy, on the other hand, brings more impact, but it’s a softer, slower bass, favouring presence over speed. It’s also a bit more crowded on this track, as Supremacy’s intimate stage can’t quite keep up with Maven II’s nimble separation and cleaner background. Supremacy has more physicality, but Maven II feels sharper and more controlled.
Ethel Cain’s American Teenager reveals another layer to both IEMs. Supremacy leans into its warm, full-bodied bass, giving the track weight and contrast against brighter high notes. Vocals are forward, but Supremacy’s upper treble energy can add a dry edge, especially on this track’s already textured high frequencies.
Maven II steps back a little here, with less bass impact but faster texture and more space for each instrument to breathe. The stage extends both in width and depth, giving the vocals a smoothness that avoids the dryness of Supremacy. The result? A more cohesive, layered presentation, where every sound has room to flourish without feeling crowded.
In short, Supremacy leans towards intimacy, warmth, and weight, making vocals sound full and textured, if occasionally dry. Maven II, however, takes the scenic route, with a wide, clean, and layered sound that feels grander and better controlled, if slightly lighter on bass impact.

64 Audio U12t ($1,999). Comparing the Grand Oriveti Supremacy with 64 Audio’s U12t feels a bit like picking between an up-close acoustic set and a high-definition concert experience. Both have their charms, but they bring different flavours to the table.
Starting with Lana Del Rey’s Mariners Apartment Complex, Supremacy impresses with a surprisingly wide stage, presenting the intro guitar riffs distinctively to the right. Lana’s vocals sound rich and warmly emotive here, spotlighting Supremacy’s strengths in clear, forward midrange presentation.
U12t, however, offers a darker background and a deeper, more holographic stage. Lana’s voice is slightly more neutral and perhaps truer to the source, with a nuanced separation of the guitar and piano that Supremacy can’t quite replicate. U12t also works some magic in the low-end, giving satisfying texture to the bass rumble. Supremacy, with its dynamic driver bass, brings a more physical presence, yet it’s a bit less layered than U12t’s finely-tuned BA bass.

In Soft Dark Nothing by Lily Kershaw, U12t captures the room’s ambiance, feeling immersive and intimate, almost as if you’re in the audience. Its imaging and layering reveal a depth and atmosphere as the strings swell and Lily’s voice floats hauntingly through the soundscape.
Supremacy, on the other hand, brings Lily’s voice upfront with the piano set back, and while it’s lush, there’s also an occasional upper midrange brightness. Supremacy’s rawness adds a touch of grit that some listeners might love, but it’s less refined than U12t’s polished, cohesive flow.
On Slow Tide by Ocie Elliott, Supremacy gives Jon Middleton’s voice a hardness that betrays its usual fluidity but also lends a certain emotional rawness. Supremacy’s midrange focus highlights the depth in Jon’s vocal timbre, blending his vocals with Sierra Lundy’s sweet harmonies for an intense, almost tangible experience.

U12t, on the other hand, offers a subtler and more controlled approach. Jon’s voice loses that slight edge and takes on a smoother, more naturally resonant tone, expanding deeper into U12t’s spacious stage. It’s like comparing a cozy live bar performance with a polished studio session – both captivating, but with U12t presenting a cleaner, more separated scene that’s ultimately more resolving.
In short, Supremacy offers listeners a visceral, intimate presentation, while U12t takes a step back, presenting everything with a sense of effortless refinement and dimensionality. For those who crave clarity and nuance, U12t is a winning choice; for those who favour a fuller, warmer sound, Supremacy has the edge.
