Short answer: the Vanatoo Transparent Zero Plus. Both are rated 3.9/5 for sound quality (#46 and #44 of 108 powered bookshelf speakers), and the Vanatoo Transparent Zero Plus costs $499.99 against $899.99 for the Kanto Tuk G2, and with sound quality even, the cheaper one is the better buy.
The Kanto Tuk G2 is the more accurate, deeper-bass option. A desk or living room pair with solid bass for its size, optical, USB-C, aptX Adaptive Bluetooth and a subwoofer output. Its measured preference score, a predictor of how neutral it sounds, is 4.61 against 4.07 for the Vanatoo Transparent Zero Plus. Its bass reaches about 52Hz before falling 3dB, against 92Hz for the Vanatoo Transparent Zero Plus. The catch: On-axis response is uneven, with elevated upper bass around 80 to 100Hz, a forward midrange near 800Hz to 1.5kHz and further ripples through the treble.
Why pick the Vanatoo Transparent Zero Plus: A compact desktop pair with an even midrange, Bluetooth and USB inputs, and automatic subwoofer crossover. It supports aptX HD Bluetooth, which the Kanto Tuk G2 lacks. It keeps a wired aux input, which the Kanto Tuk G2 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.
Buy the Vanatoo Transparent Zero Plus. Both are rated the same for sound quality, and it costs $400 less than the Kanto Tuk G2.
