Short answer: the Topping MA4 is the proven choice, measured and ranked among powered bookshelf speakers, while the newer Kanto YU4 G2 has no independent measurements yet and can only be compared on specs.
What the Kanto YU4 G2 offers: 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.
What the Topping MA4 brings: The selected manufacturer-supplied Klippel data shows a 1.6dB span from 300Hz to 5kHz, bass reaching -3dB around 50Hz, and preference scores of 5.64 standalone and 7.83 with an ideal subwoofer.
On paper: The Topping MA4 is rated down to 49Hz against 60Hz, though makers quote these at different tolerances. The Kanto YU4 G2 has more amplifier power, 110W against 75W.
Buy the Topping MA4 if you want a speaker whose sound quality has been measured and ranked. It also has deeper rated bass and XLR inputs.
Buy the Kanto YU4 G2 if you want more power, an optical input, RCA inputs, an aux input and Bluetooth, and you can wait for measurements to confirm how it sounds.

The Two Speakers In Full
Kanto YU4 G2: $449.99 per pair Kanto eBay
Older models: the Kanto YU (rated 3.7/5) and the Kanto YU4 (rated 3.3/5).
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 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.

Topping MA4: $400 per pair Audiophonics eBay
Pros: The selected manufacturer-supplied Klippel data shows a 1.6dB span from 300Hz to 5kHz, bass reaching -3dB around 50Hz, and preference scores of 5.64 standalone and 7.83 with an ideal subwoofer. That is strong measured tonal performance for a compact monitor. Its analog crossover and balanced XLR connection suit an existing audio interface. Measured bass extension of 49.8Hz (-3dB).
Cons: The native listening-window response is not as smooth as the leading Genelec and Neumann measurements. No USB, Bluetooth or built-in room-correction DSP: source control and correction need external equipment. Bass extension alone does not establish clean output capability. On-axis narrow-band deviation measures 0.503dB and listening-window smoothness a moderate 0.44.
