Short answer: the Kanto ORA4. It ranks #12 of 48 powered bookshelf speakers by sound quality (rated 3.8/5) at $449.99 and is still sold new; the Kanto YU4 ranks #23 (rated 3.3/5) and is discontinued, so it is only an option used. The Kanto YU4’s replacement, the Kanto YU4 G2, is rated 3.6/5 at $449.99.
The Kanto ORA4 is the better-sounding option. Compact desktop speakers with good sound for the size, deeper bass than most desk speakers, and USB-C and Bluetooth inputs. The catch: Its score here is our estimate: spinorama.org hasn’t published numeric data for it yet, so we traced Erin’s Audio Corner’s published charts, which put its preference score with an ideal subwoofer at roughly 6.9, level with the better small powered speakers but short of the best.
What the Kanto YU4 does well: A compact powered pair with phono, optical and Bluetooth inputs, a remote and a subwoofer output. It supports aptX Bluetooth, which the Kanto ORA4 lacks. It keeps a wired aux input, which the Kanto ORA4 lacks. The tradeoff: Standalone preference is only 2.89, with a -3dB point around 86Hz and a 4.2dB midrange response span.
Buy the Kanto ORA4. It is rated higher for sound quality and still sold new, while the Kanto YU4 is discontinued.
