Short answer: the Audioengine A5+ Classic. It ranks #37 of 108 powered bookshelf speakers by sound quality (rated 4.0/5) at $399 and is still sold new; the Kanto YU6 ranks #41 (rated 3.9/5) and is discontinued, so it is only an option used. The Kanto YU6’s replacement, the Kanto YU6 G2, is rated 3.9/5 at $549.99.
What the Audioengine A5+ Classic does well: A simple powered bookshelf pair with fairly balanced sound and no separate amplifier needed. It keeps a wired aux input, which the Kanto YU6 lacks. The tradeoff: The measured -3dB point is around 69Hz, and the upper-bass recession can reduce body in voices and instruments.
What the Kanto YU6 does well: A powered bookshelf pair with a phono input, optical, Bluetooth and a remote, a simple multi source system. 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.
Buy the Audioengine A5+ Classic. It is rated higher for sound quality, and the Kanto YU6 is discontinued, so it is only available used.
