Short answer: the Audio First Fidelia. It ranks #1 of 101 bookshelf speakers by sound quality (rated 4.8/5) and is still sold new; the Q Acoustics 3020i ranks #80 (rated 2.4/5) and is discontinued, so it is only an option used.
The Audio First Fidelia is the more accurate, deeper-bass pick. 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. Its measured preference score, a predictor of how neutral it sounds, is 6.45 against 3.86 for the Q Acoustics 3020i. Its bass reaches about 53Hz before falling 3dB, against 82Hz for the Q Acoustics 3020i. The catch: Kit assembly required; lower sensitivity (~83-85 dB vs. typical 85 dB average) demands adequate amplifier power.
What the Q Acoustics 3020i does well: UK-designed (Finkteam) with attractive styling, including recessed binding posts and custom connectors. The catch: On-axis response shows a rising upper-frequency trend and a dip in the 2-4kHz crossover region alongside two resonance-related dips; a significant resonance appears at 366Hz in the waterfall plot.
Buy the Audio First Fidelia. It is rated higher for sound quality; the Q Acoustics 3020i is no longer sold new.

Q Acoustics 3020i: $314.99 per pair Discontinued eBay
Newer model: the Q Acoustics 3020c, ranked higher, estimated 2.6/5.
Pros: UK-designed (Finkteam) with attractive styling, including recessed binding posts and custom connectors. Vertical directivity is good enough that the tweeter doesn’t need to be exactly at ear level. With EQ correction, especially high-frequency shelving and a sub-40Hz high-pass filter, Amir found performance “improves substantially.”. Measured bass extension of 82.0Hz (-3dB).
Cons: On-axis response shows a rising upper-frequency trend and a dip in the 2-4kHz crossover region alongside two resonance-related dips; a significant resonance appears at 366Hz in the waterfall plot. Horizontal directivity is narrow and uneven due to a woofer/tweeter beamwidth mismatch. Amir cautions the speaker is “merely a distortion generator” if played too low, and its low impedance demands a quality amplifier. Without EQ, Amir “can’t recommend the Q Acoustics 3020i.”. Discontinued; Q Acoustics now sells the 3030i and 3010c in its place.
