Short answer: the Kali Audio IN-5. It ranks #27 of 108 powered bookshelf speakers by sound quality, rated 4.2/5, at $898. The Vanatoo Transparent Zero Plus ranks #46, rated 3.9/5, at $499.99, $398.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the Vanatoo Transparent Zero Plus: A compact desktop pair with an even midrange, Bluetooth and USB inputs, and automatic subwoofer crossover. It keeps a wired aux input, which the Kali Audio IN-5 lacks. The catch: The measured -3dB point is around 95Hz, with a much lower F10 in the original review; this is not flat bass to the low-50Hz region.
The Kali Audio IN-5 is the more accurate, deeper-bass pick. An affordable three way coaxial studio monitor with an even midrange, good bass depth and placement switches. Its measured preference score, a predictor of how neutral it sounds, is 5.12 against 4.07 for the Vanatoo Transparent Zero Plus. Its bass reaches about 45Hz before falling 3dB, against 92Hz for the Vanatoo Transparent Zero Plus. The catch: Local listening-window irregularities remain despite the small overall midrange span.
Buy the Kali Audio IN-5. It is rated higher for sound quality, and the $398.01 you would save on the Vanatoo Transparent Zero Plus does not close the gap.
