Short answer: the ADAM Audio A4V, if you are buying new. The Kanto YU6 ranks higher than it (#41 vs #67 of 108 powered bookshelf speakers, 3.9/5 vs 3.6/5) but is discontinued, so only consider it used; the ADAM Audio A4V is still sold new at $1,079.98. The Kanto YU6’s replacement, the Kanto YU6 G2, is rated 3.9/5 at $549.99.
What the ADAM Audio A4V does well: A compact studio monitor with onboard DSP, placement controls and room correction support for tricky rooms. The tradeoff: A small average-deviation figure hides a major localized response irregularity: the selected measurement spans 10.8dB from 300Hz to 5kHz, and listening-window narrow-band deviation is 0.547.
The case for the Kanto YU6: A powered bookshelf pair with a phono input, optical, Bluetooth and a remote, a simple multi source system. The tradeoff: 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 ADAM Audio A4V, since the Kanto YU6 is discontinued and only worth hunting down used.
