Short answer: the Audio First Fidelia. It ranks #1 of 87 bookshelf speakers by sound quality; the Q Acoustics 5020 ranks #73.
What the Q Acoustics 5020 offers: Attractively finished compact standmount with a 5-inch Continuous Curved Cone woofer and carefully engineered cabinet details. Erin found distortion well controlled at normal levels: below 1% down to about 50Hz at 86dB/1m. Its 87dB measured sensitivity is unremarkable rather than hard to drive, and it maintains acceptable output for typical 80-85dB listening. The rear port can be plugged for placement flexibility. Watch for: Erin found the tonal balance distinctly too crisp, forward and treble-heavy: the top end is roughly 3-5dB elevated while the 1-3kHz region is recessed, so vocals change level unnaturally as they move through their range. The shallow woofer crossover and steeper tweeter slope contribute to the off-axis discontinuity, while the port has a strong 1kHz resonance. Bass is limited: Erin measured F3 103Hz and F10 48Hz; at 96dB distortion reaches about 3% by 100Hz, and he bottomed the woofer when pushed hard. He preferred the less-expensive 3020i’s linearity and did not recommend the 5020 for neutral listening without EQ.
What the Audio First Fidelia offers: Kit speaker offering exceptional value and tonal accuracy; chosen by reviewer as reference standard for future speaker tonality comparisons despite 1,250 USD price point. Achieves bass extension to 53 Hz (F3) and 38 Hz (F10) from compact cabinet. Direct-from-manufacturer availability eliminates retailer markup. Watch for: Kit assembly required; lower sensitivity (~83-85 dB vs. typical 85 dB average) demands adequate amplifier power. Only available direct from UK manufacturer with associated shipping costs and lead times. Trade-off between compact driver configuration and maximum dynamic output.
Buy the Q Acoustics 5020 if the price matters more than sound quality. Buy the Audio First Fidelia if sound quality matters more than the price.
