Great timbre good on classical. Detailed and analytical, but too Safe.
Youtube Video Summary

The 2024 Cadenza 12 makes a strong first impression with premium presentation, though the accessories aren’t flawless. The stock cable looks gorgeous and offers swappable terminations (4.4 / 3.5 / 2.5), but it’s stiff and tricky to coil into the compact case. The metal shell is well-contoured and comfortable with a sensible nozzle lip, yet certain tips can pop off too easily. Overall build feels upscale and weighty without being cumbersome—just expect some practical quirks.

Tonally it sits neutral with a gentle bass lift: clean sub-bass presence without thunder, crisp highs with smooth extension, and a relaxed upper-mid energy that keeps fatigue low. Resolution and imaging are technically adept, but the tuning plays things safe—polished and airy rather than punchy or electrifying. On graphs and by ear it evokes classic “reference” curves (think early Monarch-style balance), trading visceral slam for control and clarity; many audiophiles will find it classy and coherent, while thrill-seekers may wish for more bite.

Against peers, it recalls sets that graph beautifully yet feel a touch reserved in the bass and presence regions. Comparisons to options like Europa highlight how a bit more sub-bass and 4–6 kHz zest can add sparkle and engagement; a light EQ lift to bass and upper mids wakes the Cadenza 12 up nicely. As delivered, it’s a refined, wide, and airy listen that prioritizes neutrality and detail over spectacle—recommended for listeners chasing a mature, low-fatigue signature rather than a high-octane ride.
