Short answer: the HiVi Swan X3. It ranks #7 of 23 powered bookshelf speakers by sound quality at $249; the Fiio SP3 ranks #19 and costs $299.99, so there is not much of a tradeoff to weigh.
What the HiVi Swan X3 offers: ASR’s Spinorama data predicts 3.13 standalone and 6.12 with an ideal subwoofer, placing its bass-normalized tonal performance ahead of several similarly small budget monitors. Listening-window narrow-band deviation is 0.420, lower than the MR3’s 0.538, indicating fewer local response irregularities by that measure. The compact coaxial layout is convenient for a small desktop system. Watch for: Not a flat reference monitor: the response spans 5.0dB from 300Hz to 5kHz and trends upward toward the treble. Bass reaches -3dB at about 79Hz, so a subwoofer remains important. Coaxial construction alone does not guarantee uniform dispersion, and the preference score does not establish distortion or maximum clean output.
What the Fiio SP3 offers: Compact cabinets and angled bases fit a small desk. The existing review found useful dynamic capability at higher frequencies, so lack of output is not the only issue. Erin’s Klippel data shows a measured -3dB bass point around 60Hz, deeper than several similarly sized alternatives. Watch for: The response rises strongly toward the treble, about 1.13dB per octave, with a recessed midrange and problematic crossover behavior. Its 2.71 standalone and 5.32 ideal-subwoofer scores do not capture the full practical impact of the review’s boomy bass and off-axis tonal problems. Changing angle trades one coloration for another. Those audible limitations weigh against it more heavily than its numerical score or build quality.
Buy the HiVi Swan X3. It ranks higher for sound quality than the Fiio SP3 and costs less, so the other one has nothing left to offer.
Skip the Fiio SP3 if sound quality matters to you. It ranks near the bottom of the 23 powered bookshelf speakers.
