Short answer: the Kanto Ren. It ranks #49 of 108 powered bookshelf speakers by sound quality, rated 3.9/5, at $474.99. The Kanto YU4 G2 ranks #64, rated 3.6/5, at $449.99, $25 cheaper, which does not close the gap in sound quality.
The case for the Kanto Ren: Audioholics measured a listening window within about 1.5dB to 20kHz with only minor directivity ripples, so it sounds accurate and balanced, with wide horizontal dispersion past 50 degrees. The catch: Bass begins rolling off around 90Hz in ground plane measurements, and the ports get noisy when pushed hard without a subwoofer, so maximum volume is modest on its own.
Why pick the Kanto YU4 G2: The second generation YU4 swaps the Kevlar woofers for 4” abaca paper cone woofers alongside 1” silk dome tweeters, and raises amplifier power to 110W RMS (160W peak) from the original’s 70W. The catch: Not on sale yet: Kanto lists it as coming soon.
Buy the Kanto Ren. It is rated higher for sound quality, and saving $25 with the Kanto YU4 G2 does not make up for the sound-quality gap.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Kanto Ren 3.7 to 4.1; Kanto YU4 G2 3.4 to 3.8). Treat this verdict as provisional.

The Two Speakers In Full
Kanto Ren: $474.99 per pair Estimated Amazon $474.99 eBay
Pros: Audioholics measured a listening window within about 1.5dB to 20kHz with only minor directivity ripples, so it sounds accurate and balanced, with wide horizontal dispersion past 50 degrees. HDMI ARC with TV remote control, USB-C, optical, RCA, aux and Bluetooth with AAC cover nearly every source, and the sub out automatically high passes the speakers at 80Hz.
Cons: Bass begins rolling off around 90Hz in ground plane measurements, and the ports get noisy when pushed hard without a subwoofer, so maximum volume is modest on its own. A deep vertical null just below the tweeter axis means it should be placed at or below ear height, and there is no app or phono input.

Kanto YU4 G2: $449.99 per pair Estimated Kanto $449.99 eBay
Older model: the Kanto YU4 (rated 3.3/5). See every Kanto YU and Tuk generation.
Same family: the Kanto YU6 G2 (larger bookshelf, estimated 3.9/5), the Kanto Tuk G2 (larger bookshelf, ranked higher, rated 3.9/5) and the Kanto TUK Grand G2 (larger bookshelf, estimated 3.9/5).
Pros: The second generation YU4 swaps the Kevlar woofers for 4” abaca paper cone woofers alongside 1” silk dome tweeters, and raises amplifier power to 110W RMS (160W peak) from the original’s 70W. Inputs cover RCA with a switchable phono preamp, optical and USB-C audio at 24 bit/96kHz, 3.5mm aux and Bluetooth 5.3 with AAC. A subwoofer output engages an automatic 80Hz crossover, and a USB-C port charges a phone. Includes a remote, speaker wire and swappable left and right channels.
Cons: Not on sale yet: Kanto lists it as coming soon. No independent measurements have been published, so it can’t be compared with the original Kanto YU4, which ASR measured, and its 60Hz to 22kHz rated response means a subwoofer is still needed for deep bass. Kanto doesn’t publish sensitivity or maximum output.
