Short answer: the Adam Audio D3v for better sound quality, the Fiio SP3 for the lower price. The Adam Audio D3v ranks #3 of 23 powered bookshelf speakers at $339.99. The Fiio SP3 ranks #19 at $299.99, $40 cheaper.
What the Adam Audio D3v offers: Excellent midrange linearity for a tiny desktop speaker: Erin’s Klippel data spans just 1.7dB from 300Hz to 5kHz. Side passive radiators help bass reach -3dB at about 51Hz, substantially deeper than the Genelec 8010A or Audio Smile LBM. Predicted preference scores of 4.47 standalone and 6.70 with an ideal subwoofer support it as a particularly useful compact system without a sub. USB-C, analog inputs and placement filters simplify desk setup. Watch for: A rising upper-frequency balance and vertical crossover interference keep it from being uniformly neutral at every angle; aim the tweeters toward ear height. The limiter reduces bass and midrange output as volume rises, with the existing review’s compression tests putting usable maximum output around 89-90dB at 1m. Deep bass at moderate volume should not be confused with high output capability.
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 Adam Audio D3v when sound quality outweighs the price for you, and the Fiio SP3 when the price outweighs sound quality instead.
If sound quality matters at all to you, skip the Fiio SP3. It ranks near the bottom of the 23 powered bookshelf speakers, so look higher up the list instead.
