Short answer: a tie on sound quality. Both are rated 3.7/5 (#39 and #40 of 67 powered bookshelf speakers) at nearly the same price ($349 vs $349.99), so choose on features and fit.
The case for the Onkyo GX-30ARC: HDMI ARC, USB-C, optical and analog inputs make it a convenient compact system for a desk or TV. The tradeoff: The response rises toward the treble by about 0.48dB per octave.
The case for the Kanto YU: RCA and Bluetooth inputs, remote control, tone adjustment and a subwoofer output make this compact pair simple to use. Watch for: Standalone preference is 3.46 and the -3dB point is about 85Hz, so it lacks low-bass weight.
Buy the Onkyo GX-30ARC or the Kanto YU on features: they are rated the same for sound quality at close to the same price.

The Two Speakers In Full
Onkyo GX-30ARC: $349 per pair Onkyo eBay
Pros: HDMI ARC, USB-C, optical and analog inputs make it a convenient compact system for a desk or TV. Erin’s Klippel data gives a 3.69 standalone preference score and 6.42 with an ideal subwoofer. The midrange response spans 3.8dB, offering usable but not reference-level tonal performance.
Cons: The response rises toward the treble by about 0.48dB per octave. Bass reaches -3dB around 74Hz, not the lower LFX value used inside the preference model. Vertical listening position affects crossover balance. Its extensive connectivity does not compensate for response irregularities, and the published tonal data alone does not establish maximum clean output.

Kanto YU: $349.99 per pair Kanto Audio eBay
Pros: RCA and Bluetooth inputs, remote control, tone adjustment and a subwoofer output make this compact pair simple to use. ASR’s measurements show a 2.9dB midrange span and a 6.38 preference score with an ideal subwoofer, supporting moderate desktop use with bass assistance.
Cons: Standalone preference is 3.46 and the -3dB point is about 85Hz, so it lacks low-bass weight. The response trends upward toward the treble and retains local irregularities across the listening window. A subwoofer adds bandwidth but does not make the speaker neutral. Connectivity is basic compared with models offering USB, optical or HDMI.
