Short answer: the Neumann KH80 DSP for sound, the KEF LSX II LT if output demands are modest. The KH80 DSP sounds near identical to the 8020D, though it carries a high price. The LSX II LT’s coaxial driver keeps the tweeter centered in the midrange, but its small drivers make it SPL-limited, with bass compression kicking in around 88-92dB/1m per speaker.
What the KEF LSX II LT gets right: Coaxial (Uni-Q-style) driver keeps the tweeter centered in the midrange. The tradeoff: Small drivers mean it’s SPL-limited: bass compression kicks in around 88-92dB/1m per speaker.
On the Neumann KH80 DSP side: Near identical sound to the 8020D. Set against that: High price.
Buy the Neumann KH80 DSP. It is rated higher for sound quality, and the $49.01 saving on the KEF LSX II LT is not enough to make up the difference.

KEF LSX II LT: $549.99 per pair Amazon eBay
Pros: The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. Erin’s measurements give preference scores of 3.93 standalone and 6.16 with an ideal subwoofer, with -3dB bass around 56Hz. HDMI and USB connectivity make it convenient for a small TV or desktop system. Measured bass extension of 55Hz (-3dB), with a measured sensitivity of 84dB.
Cons: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors. The existing review finds bass compression around 88-92dB/1m and rising distortion at higher levels, so the small drivers suit close listening rather than a large room. This LT version has no analog input; a turntable cannot plug straight into it.

Pros: ASR’s selected Klippel measurement has a 1.4dB midrange response span and virtually no overall on-axis tilt. Scores of 5.03 standalone and 7.39 with an ideal subwoofer indicate excellent tonal accuracy in a compact monitor. The waveguide and steep crossover provide useful control of reflected sound, while placement filters help compensate for a desk or nearby boundaries. Existing multitone testing supports good moderate-level clarity. Measured bass extension of 57Hz (-3dB), with a measured sensitivity of 91.9dB.
Cons: Bass reaches -3dB around 59Hz in this measurement, less deep than the KH120 II. Output protection and increasing multitone distortion limit loud listening, especially in the bass. Room reflections and listening distance can alter perceived treble balance despite its flat direct response. Calibration equipment adds to the cost; the preference score is not a measurement of maximum clean output.
