Short answer: the ELAC Debut 2.0 B5.2. It ranks #86 of 160 bookshelf speakers by sound quality, rated 3.2/5, at $269; the Q Acoustics 5020 ranks #140, rated 2.2/5, and costs $1,199, which makes this an easy call rather than a real tradeoff.
The ELAC Debut 2.0 B5.2 is the more accurate, deeper-bass option. Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. Its measured preference score, a predictor of how neutral it sounds, is 5.02 against 3.63 for the Q Acoustics 5020. Its bass reaches about 60Hz before falling 3dB, against 103Hz for the Q Acoustics 5020. Watch for: Erin measured a broad +3dB step beginning around 1.5kHz; the resulting elevated upper range sounds tonally uneven even though it is not a narrow, sharp resonance.
Why pick the Q Acoustics 5020: Attractively finished compact standmount with a 5-inch Continuous Curved Cone woofer and carefully engineered cabinet details. The tradeoff: 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.
Buy the ELAC Debut 2.0 B5.2. It is rated higher for sound quality than the Q Acoustics 5020 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
ELAC Debut 2.0 B5.2: $269.00 per pair Amazon eBay
Newer model: the ELAC Debut 3.0 DB53, ranked higher, estimated 3.9/5.
Same family: the ELAC Debut 2.0 B6.2 (larger bookshelf, rated 3.5/5).
Pros: Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. Erin demonstrated that a single high-shelf filter centered near 1.6kHz, about -2dB with Q near 2, substantially improves linearity. Moderate roughly +/-50-60 degree horizontal coverage balances room interaction and image focus. The front port makes close-to-wall placement practical. Erin measured F3 near 60Hz and F10 near 40Hz, useful extension for a compact 5.25-inch two-way. Harmonic distortion is mostly below 1% at 86dB/1m, and low-frequency distortion is better than its size might suggest. Compact cabinet and inexpensive pair pricing make it a workable EQ-assisted desktop or small-room system. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 83dB.
Cons: Erin measured a broad +3dB step beginning around 1.5kHz; the resulting elevated upper range sounds tonally uneven even though it is not a narrow, sharp resonance. Native response spans roughly -2.6 to +4dB around the mean, so this is not a neutral speaker without correction. Sensitivity is only about 83dB after correcting the shelf, demanding materially more amplifier voltage than ELAC’s 86dB specification implies. Vertical response changes substantially outside roughly +/-10 degrees of tweeter height. Dynamic compression is the larger limitation: at the highest sweep level it loses roughly 1-1.5dB through the midrange, and even the 86dB trace shows unusual nonlinearity that may involve crossover heating. At about 96dB, multitone distortion rises audibly around 600Hz; an 80-120Hz subwoofer crossover helps but does not turn it into a high-output design. Erin recommends the larger B6.2 instead when EQ is unavailable.

Q Acoustics 5020: $1,199.00 per pair Amazon eBay
Same family: the Q Acoustics 5010 (smaller bookshelf, ranked higher, estimated 3.5/5), the Q Acoustics 5040 (smaller floorstanding, rated 4.1/5), the Q Acoustics 5050 (larger floorstanding, estimated 4.3/5) and the Q Acoustics 5090 (center, estimated 3.7/5).
Pros: 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. Measured bass extension of 103Hz (-3dB), with a measured sensitivity of 87.1dB.
Cons: 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.
