Sound Analysis

There's a integrated and realistic feel to the sub-bass range. The bass is present and blended, delivering a grounded but moderate foundation. Bass feel is consistent and blends well without stealing the spotlight. Midrange fundamentals stay laidback and clean. The upper mids are smooth, offering a more forgiving presentation. Lower treble is glittery and crisp, enhancing presence and detail. Upper treble is airy and articulate, adding shimmer and air. The soundstage is broad, placing instruments far across the field. Details are defined and bring music to life. Layering is articulate and textured, creating excellent separation. The mix stays transparent even with overlapping elements. Weight feels consistent, neither too light nor too dense. There’s enough impact to keep the music lively. Sibilance is noticeable but kept tolerable. Most instruments sound pleasant and relatively true. The signature is natural and suits most music. There’s enough definition to highlight instrument character.
