Short answer: the Kanto YU6. It ranks #29 of 67 powered bookshelf speakers by sound quality, rated 3.9/5, at $579.99. The Onkyo GX-30ARC ranks #39, rated 3.7/5, at $349, $230.99 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Kanto YU6: ASR’s measurements give preference scores of 4.28 standalone and 6.89 with an ideal subwoofer, stronger than several smaller lifestyle pairs. Watch for: Local response variation remains despite the mild overall tilt: the midrange span is 3.8dB and listening-window narrow-band deviation is 0.419.
What the Onkyo GX-30ARC does well: 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.
Buy the Kanto YU6. It is rated higher for sound quality, and saving $230.99 with the Onkyo GX-30ARC does not make up for the sound-quality gap.

Kanto YU6: $579.99 per pair Amazon eBay
Pros: ASR’s measurements give preference scores of 4.28 standalone and 6.89 with an ideal subwoofer, stronger than several smaller lifestyle pairs. Phono input, optical connections and remote control make it useful for a simple multi-source system. The overall response trend is close to level rather than strongly tilted.
Cons: Local response variation remains despite the mild overall tilt: the midrange span is 3.8dB and listening-window narrow-band deviation is 0.419. Bass reaches -3dB around 75Hz, so the preference model’s 58Hz LFX value should not be quoted as full-level bass extension. A subwoofer improves bandwidth but does not remove tonal irregularities.

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.
