Short answer: the Kali Audio IN-UNF, if you are buying new. The Kanto YU6 ranks higher than it (#41 vs #83 of 108 powered bookshelf speakers, 3.9/5 vs 3.3/5) but is discontinued, so only consider it used; the Kali Audio IN-UNF is still sold new at $699. The Kanto YU6’s replacement, the Kanto YU6 G2, is rated 3.9/5 at $549.99.
The Kanto YU6 is the better-sounding pick. A powered bookshelf pair with a phono input, optical, Bluetooth and a remote, a simple multi source system. The catch: Local response variation remains despite the mild overall tilt: the midrange span is 3.8dB and listening-window narrow-band deviation is 0.419.
The case for the Kali Audio IN-UNF: A desk system of small coaxial satellites and a bass module, with DSP placement controls and USB-C, optical and balanced inputs. It keeps a wired aux input, which the Kanto YU6 lacks. The catch: The intended desk geometry is part of the acoustic design.
Buy the Kali Audio IN-UNF if you want one new; the Kanto YU6 is discontinued, so only look for it used.
