Short answer: the Kanto YU. It ranks #39 of 65 powered bookshelf speakers by sound quality at $349.99; the Adam Audio A4V ranks #42 and costs $599.99, so there is not much of a tradeoff to weigh.
What the Adam Audio A4V offers: Compact monitor with onboard DSP, placement controls and room-correction integration. ASR’s Klippel data gives a -3dB point around 59Hz and preference scores of 3.02 standalone and 5.43 with an ideal subwoofer. Its adjustment facilities are useful when placement or tonal correction is needed. Watch for: 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 native response should therefore not be called smoothly neutral. Correction potential is not the same as stock performance, and analog audio inputs mean a separate interface is needed for USB sources.
What the Kanto YU offers: RCA and Bluetooth inputs, remote control, tone adjustment and a subwoofer output make this compact pair simple to use. ASR’s measurements show a 2.9dB midrange span and a 5.51 preference score with an ideal subwoofer, supporting moderate desktop use with bass assistance. Watch for: Standalone preference is 2.59 and the -3dB point is about 85Hz, so it lacks low-bass weight. The response trends upward toward the treble and retains local irregularities across the listening window. A subwoofer adds bandwidth but does not make the speaker neutral. Connectivity is basic compared with models offering USB, optical or HDMI.
Buy the Kanto YU. It ranks higher for sound quality than the Adam Audio A4V and costs less, which settles it without a real tradeoff to make.
